Thanks for the file. Great Sound!!! I’m using Tidal streaming on a dedicated server and ASIO4ALL and Virtual Cable as per your suggestion in manual.
I have no idea how effective competing software offerings are, but your Fidelizer Pro software program is seriously effective and whose improvements are patently real. I mean, enjoyably real improvements that are not subtle at all. Wit…
Great job! I also had my brother & friend buy your product system never sounded better fast service. Dean from Canada! They are also very very happy with Fidelizer Pro worth every penny!!!!!!!!!!!!!
Sound quality is a little subjective but I have a dedicated PC for storing my music and passing it to my audio system so I love your concept of minimizing Non audio processes and giving Windows a chance to provide the least affected bit per…
Love the software, it makes such a difference to my listening.
I have tried the Fidelizer for a week and i’m impressed for the improvement on all fronts. Great job.

Just want to let you know, the effect is AMAZING. Thank you and I think that’s money well spent on my side
The program is actually awesome!!! I did not think, that it still brings out so much from our music.
works perfect now 🙂 ; should have bought Fidelizer way earlier!
Sounds Amazing on my htpc output spdif to my Marantz pre-pro from my Sound blaster x-Fi fatality pro, made a big diffence is the details. Thanks you so much for the product and thank you ahead of time for listening to my questions.
Thank you much! Congratulations. Immediate and extraordinary improvement, even over the free version. Keep it up, Thomas
Ok, so far the usual :
Quieter backgrounds, a more ‘dramatic’ presentation. Dynamics.

I managed to get the program installed before I left for work. It sounds really good…smooth and musical.
My congratulation for your program.
It works fine and the improvements are easily audible: mostly I have found a better bass articulation, more overall transparency, and a better depth of image.
Hi, it works fantastically! Running it at purist level – usb into Geek Pulse Fi DAC . The difference is amazing as I’m sure you know. The background is so much blacker and the sound image more 3 dimensional. Many thanks for a great and easy to use pr…
It works very well. Maybe better than expected 🙂
Sound quality is improved, silence where to be, better definition of soundstage as far as I can judge.

Bravo, Windows X! After installing FP on the second PC (control PC), I had a listen. It sounds as if my DAC had been upgraded to a much more expensive one. Now the setup is very much to my liking: sibilance (high noise) is mostly gone to the extent t…
Thank you. I have tried your free version few times in the past, right from the first versions when you released the program. I’ve never been able to hear clear difference made by it but yesterday evening when I auditioned once again, …
Yes I tried it and it sounds great. Made the sound very clear and detailed. Also took out some of the bass so I had to add more bass on the amplifier. It was strange. But I like it that way.
Hello! All works well! My system with JRiver began to sound bladeturn and clean. Thank you! All the best!
thanks for the Download Link!
I installed Fidelizer Pro 7.2 on my AudioPC. I do not exactly how and what you are doing in detail by your software, but the result at least in my system sounds phantastic!
I’m seriously thinking about insta…
Thank you for sending me the download link for my copy of Fidelizer Pro.
I downloaded the software and installed it into my AUDIO PC this morning without any problems and the product is running fine.
The result is pretty spectacular.
Dear Keetakawee Punpeng,
Thank you for your very quick response. I have installed Fidelizer Pro easily and use it together with Jplay and Tidal followed by two vst-hosts with an ambiophonic vst-plugin and an acourate-convolver-plugin respectively.
Well having a $50.000 system and expecting a $70 program to enhance the sound quality is completely ridiculous! I was wrong! This is simply awesome , I’m so happy I stumbled upon fidelizer!
First impression is the voices, so clear and stand…
Just thought I’d let you know that everything is working and I do think the audio has improved.
Running through a Chord 2qute dac it sounds fantastic but im still to make up my find on wasapi or asio ???
Dear Mr. Punpeng,
I just had to write and tell you how thrilled I am with your new Fidelizer Pro.
Not only does it provide some of the best sound I’ve ever gotten out of my system, but it does it in such a trouble free manner.
I’ve used many types …

Hello Keetakawee, I understand, you are passionately committed!
I imagined I was doing or understanding something wrong.
First impressions of the Fidelizer optimizations are great! So much that I became suspicious! I witnessed big changes when instal…
I am really really impressed by the fluidity and analog like sound of my computer by using Fidelizer. Last night whole family sit and listen music and I feel absolutely no fatigue after 3 hours of continuous long listening.
I am totally pleased with the Fidelizer Plus 7.1!
I can work at my PC hearing music without any interrupts with working Bluetooth an WLAN. I use it in consumer audio configuration. The improvment from the free version to the plus version is clear…
Great Job! Wider stage, airier sound, more palpability: phantastic. Thank you very much
best for you

Well… you nailed it! 🙂
As the Fidelizer free/pro – A/B test is very difficult to accomplish (just with two exactly equal computers), what I did was:

I’m enjoying the software very much. Previously I had used Free Fidelizer in addition to running my PC with Win8 in safe mode and doing much of the service closures myself. I tried this same path with Fidelizer Pro but found that starting windows i…
Fidelizer opened Tidal right away
Sonic impressions – 4 BASICS
– instrument separation
– imagining – instrument location in stage
– more 3 dimentional Staging – especially depth layers
– on massed strings – less digital shrill – less DIGITITIS
My initial reaction is Wow! I would compare the difference to same level as that the uptone regen made…but in different areas. I will have to wrap my ears/brain around that. But basically the staging and layering is imediately noticeable …

It’s running on my Audio PC. The sound is very good! 👍
As you know I just purchased Fidelizer Pro. I use it with JPlay and AO 2.0 with ROON on a dedicated audio PC I built myself and continue to improve. The PC is connected to Berkeley Alpha USB and DAC 2 to my beautiful CJ ART amps then to Amphion 7L sp…
Just wanted to say the pro version takes everything to the next level, really worth the upgrade! 👍
I run my tested and I can approve that it all sounds great and the upgrade from the free version is much noted. I found the purist / player with no network worked best for me.
Hi Windows X
Thanks for the update.
I have recently installed Win Server 2012 R2 with AO which I run in core mode with a foobar shell. The sound is fantastic.
It works excellent and a very good sound.
Thank you Keetakawee. It sounds great! Been listening for a few hours now. Thanks for also putting up with me doing things backwards.
Thanks so much for developing this amazing product! Very much appreciated 😊 I really like and trust your software concept. It makes a whole lot of sense.
I successfully installed it on my HTPC and I’m running it as Audiophile / Media Center. First …
Thank you very much! Now my CyberLink Power 14 -player plays like never before.
I downloaded and installed Fidelizer Pro. Since I use a PS Audio Perfect Wave II, I set it up in Network Transport mode. The sound improvement is greater than that of standard Fidelizer, a broad and high soundstage when I have set the absolute pha…
Thanks, i installed, and works.
I not heared too big diference compared to before installing status. It is more analogue, better detail, but this diference is tot as big as i readed from forum and webpage.

Thank you brother the sound was very good.

Hi There Keetakawee,
Well I installed your software and it really improves the sound! The magnitude of the improvement was surprising and welcome. You’ve done a great job with your software.
Hi Windows X,
Thanks for the build, it has made a great improvement, especially picture and sound as I run video and audio through JRiver.
In reference to my previous e mail all is working great with jplay. A definate improvement in sound quality. Thanks.

Thank you for your product, which is working wonders indeed. Will have some questiones soon. Thank you very much again for now.

I gotta tell you X. This program is by far the most significant upgrade in my headphone journey. It’s quite a revelation! I can’t believe what I’ve been missing since joining this hobby.
Best $70 ever spent!
Hi, I have an old, entry entry audio setup, but (with Fidelizer) improvement is tangible.
Thanks for Your work.
My name is Tom Shields I just purchased Fidelizer pro without even trying Fidelizer first. After I allowed it to do its thing I was blown away.
The sound quality is very good indeed in 6.9, and has been so even from version 6.5. That’s why I find it unnecessary most of the time to install new versions.
Fidelizer has taken the clean and accurate but a bit clinical sound of my Windo…
Thank you very much for fast sending. Sound is perfect !. Sound is really 3D right now, sound stage just full blending my room which is quite large (photo attached).
I have to say that Pro version is worth every cent
Thank you, Keetakawee,
The first results are very good altough I need to do some finetuning (no easy access to the NAS at the moment). I will let you know. I already hear increased focus and better placement compared to the free version which was an …
thanks for the update. Look forward installing the new version. I was really surprised about the results using the former one. It sounds better in contradiction to some comparisons to be found in the internet.
I listened to a few songs with just the free Fidelizer, and installed the PRO version. After a minute of listening the first song, I knew I was in for a treat.
The music just flowed better and I felt it had more warmth to it. The…
with your app, the sound of the digital part of my system have reached the quality of the analog part

Fidelizer is great. The dynamics and musicality have improved significantly. Especially combined with Process Lasso.
Thanks for the good work.
Yes, I do believe that when Fidelizer is engaged there is a greater sense of spaciousness, more dimension and air. Very similar to what I hear as jitter levels decrease.
I have gone to great effort to minimize the transfer of noise down th…
Thank you for sending a new version of Fidelizer Pro to me.
Today I made it sure that this new version software runs correctly in my music PC.
Fidelizer brings me a lot of enjoyment in listening to music with its high quality PC optimizations.

I’m using an Apple Mac mini running Bootcamp, Windows 8 and JRiver Media Center in a headless configuration using JRemote.
I use Fidelizer since 2 years and it’s a great work ! For me, the sound improvement it’s better than Jplay alone. I try some linux solutions, Volumio with Cubox, Daphile on my PC. Volumio sound great but it’s complex for me and i prefer F…
I am enjoying listening with Fidelizer Pro operating. I don’t find I can definitely identify specific improvements but feel over all the sound is clearer and allows bigger stage with more precise instrument location. Perhaps the bass is a bit t…

2 thumbs up for this great sw,worth of money spent.
Thanks, it’s working fine on my new laptop. It makes a big improvement to the sound quality.
I’ve installed the program and everything appears to work as it should. I listened attentively to my standard comparison recordings for several hours with another Fidelizer owner and we both saw improvements.
Thank you for offering a product like Fidelizer. I began my venture into Hi Res computer audio a little over four years ago (which I guess makes me a veteran of sorts LOL). I have along the tried many different types of computer builds and var…

Hello, I’m sorry, I do not speak English so I can describe how wonderful your program is.
Congratulations on your work.
This seems to be working better, and it sounds better than ever. I think that if you don’t select the device you are using for sound as the default, it will be shut off. Only got to listen to it for an hour. Another step closer to analog with the b…

Dear Khun Keetakawee,

laptop with an i3 processor and a portable DAC could produce audiophile qua…
Fidelizer 7.0 is already running. No problems with installation, all functions still working.
And it is a step to more music again. Music comes more relaxed, more “analog”. Most improvement I can hear at soundstage. T…
I am really enjoying especially in combo with a Jitterbug.
I am very happy to get the Pro version without any regret, and 100% money worth. Thumb up. There is improvement with subsonic low and high frequency with much purity sound.
Your software is fantastic! I had been having trouble [I thought] with my Yulong DA8 DAC: on certain tracks and especially on Sarah MacLachlan’s “Angel”; there was a terrible distortion on vocal peaks. I discovered through research that this might be…
Egregious Windows X,
I’m testing my new Fidelizer Pro. The improvment is evident: more presence, more detail and (for me very important) increased softness of Highs. So my digital collection is even more appreciable.
Thanks 😊 after hours of experiments I can confirm that statement, about the sound, well is like a I having a new audio system in my house it’s amazing what’s Fidelizer can do , good recordings gain a holografic signature we get involved by the music …
I cried when I first heard it. This is so close to LP fidelity. I’m using your software on my own custom build paired with a benchmark dac2 and the focal elear headphones. Just amazing!
Great, thank you. I’ve purchased the Plus version and it sounds great so far!
thanks so much for generating the program so quickly this (my) morning. I downloaded in the meanwhile and did a bit of listening – so far: absolutely great! Even more transparency/veil off/details compared to the trial version and it feels like hav…

Listening and enjoying so far. Soundstage seems tighter and an occasional stutter with dsd I’ve been trying to diagnose seems fixed.
After using Fidelizer Pro,the sound is more living,more expression and more dynamic.

I don’t know how you can make this…. but you are a genius!! Great sound….!!
HI , I just tried HQplayer with purist level and audioplayer option , it sounds very detailed and much better than jplay+foobar.
With HQP , Fidelizer really improve the SQ without side effect.
I do appreciate your efforts to improve Fidelizer and send out the upgrades. Just yesterday I installed the Melodious MX-U8 on my streaming PC (and of course Fidelizer 6.9). I am really enjoying the music with each improvement.
I’ve been very happy with the improvement in sound quality that Fidelizer has made to my Logitech Media Server based system since buying it last week. It’s improved clarity and detail through my Logitech Touch player which sounds more “relaxed” playi…

I also found Keetakawee very helpful when I was setting it up.
All questions were answered very promptly.
My first brief listening impressions are that Fidelizer Pro has smoothed out the digital “edge” and enhanced the detail and sound stage width on the few tracks I had time to listen to. The difference is not huge (to my ears, with my system, in my roo…
Awesome. Everything works.)))
Included Nelly Furtado-2017-The Ride Tap Dancing and not learned a thing appeared pensive beautiful floating bass in chorus.
Cool. The sound became much better.
Further to my earlier email below, in which I said that, having got everything working again, I would do listening comparisons between 6.11 and 6.12, I thought that you might like to hear of my impressions and so, here are my comment…
this is just to let you know that it is working perfectly. My feeling is a clearer sound and a more precise scene construction.
Thank you very much, it works really well and it seems to consume less resources than the normal version.
Not having to start it up each time is the main reason why I bought it, was not actually expecting better sound 🙂
But somehow the sound is also …
So happy with Fidelizer Pro now!!! Sound is just amazing! Compared to friend’s notebook with Fidelizer free version and my notebook won!!! 🙂 A time ago with both Fidelizer free on our notebooks – they were almost the same sounding!!! Thank you very m…
I’m sitting right now listening. It is unbelieveable how moch better Server 2016 sounds. Especially orchestral music.
Firstly I would like to say I have been using Fidelizer for some time now and moving into the pro version a short while back. It does everything you say to major sonic advantage. I run many audio systems both Windows and OS X based in my listenin…
I would like to give a little feedback. It works!
The sound becomes more dynamic, you can better hear small details and all in all it is a more musically involving experience.
The effect is less pronounced with Workstation optimization more with Extr…
Many thanks for your quick and efficient service.
Listening is as happy as possible. 🙂
I have compared my system with and without fidelizer. I note that there seems to be a more three dimensional image, cleaner, and correct me if I am wrong: Almost seems like I can turn the vomume down and still hear the details. Maybe it is a lack…
I just wanted to touch base to let you know that my Pro install went perfectly and music is sounding better than ever (Devialet + AIR 3 beta + RoonServer). I set it up with the Network Render profile.
I had to email you to say a big thanks after spending a few hours listening with only Fidelizer pro on the Audio PC it is without doubt he best my music setup has sounded.
The sound heard now is more and very realistic, I could sett…
Hallo and thank you,
after some years with free Version (up 1.x) i decide to update together with win 10 Pro.
Easy installation, great sound Improvement. The Pro Version is even better sounding !
I am really happy with.
“My Setup : Extremist
Very nice indeed! I admit I was skeptical, but a friend convinced me to try out the Pro version. I’m an audiophile and chose to go with the “Extremist” level with use on my J.River MC20 and my Windows 10 desktop. I use a USB DAC with CDs ripped to fl…
Thanks, Keetakawee – I was able to successfully update to the Fidelizer Pro. The music is really sounding amazing, thanks very much.
Thanks for a great product.
I’m impressed, just could not believe the effect of the software will be so great. Since the first moment they were immediately noticeable improvements, the scene is darker, more air between instruments, three-dimensional sound image, unb…
Nice software with a good improvement on my audio system
All I can say is wow, I am in audio heaven. I cannot believe the difference between the free version and the Pro version, it is simply amazing, thank you so much for making Fidelizer Pro work so well. You are a genius.I wish you a long…
Tanks for your Fidelizer update 7.3
This is a big upgrade. The imaging is more precise. Complex orchestra are more more clean less comfuse. The bass are better, the medium are better.
The sound is more dynamic and i understand more lyrics.
The only l…
Many thanks. This is my second purchase from you. I know it works extremely well :). I have one installed on my audiopc at home. This one is for my laptop when away from home. Keep doing what you are doing 🙂
Thanks, works perfectly!
There’s been some debate as to the effectiveness and even need to improve the computer streaming into the microRendu. Many believe what happens to the stream before the microRendu is purified by going through the microRendu itself. Thus the theor…
Dear Keetakawee Punpeng!
Thanks a lot!
Big improvement!!!! Finally where I wanted to arrive!
and best wishes,
Hi mr. Windows X,
I installed your software on my dedicated audio player. The system was already tuned by the Highend Audio Pc app from Audiophil together with Jplay 6 beta running on windows server 2012. Even on this fully tweaked system there was a…
Well it is early days listening, but all I can say the Pro version, is just WOW! And by a considerable margin over the other versions, by some margin I might add… The pro version is worth every penny….
Immediate observations include, im…
It seems to make good work!
More air and sweetness. The sound level seems to be lower than before, but i think this is in my mind, because of the softer sound.
I think my setup can be optimized deeper, but this is a good step
Thanks a lot
Thank you very much, the music took on detail and cleanliness. Played by Win 8.1> JRiver 22> ifi IDSD Nano> Ultrasone HFI-780. Files 24/96 and more. I regard good job.
I am really loving your software. I really made my system sound alive.
I received your product, installed it and everything worked fine. I use it on a small Zotac nano – actually the first one they put out about five years ago. I use Win 10 Pro and HQPlayer’s NAA.
The listening experience is phantastic, especially DSD r…
I am very impressed with yours software.the sound is now much more analog, if i can put it this way,less distortion.
Fidelizer is already a must have software in my list for hi end SQ.
I’ve tried out Fidelizer Pro for only a couple of days and I’m stunned. What an improvement! It’s just like magic. The sound is more natural, detailed, bigger, firmer, airier. The list just goes on and on.
You really are in service for a…
I’ve sucessfully installed your fidelizer pro and have been using them for quite a while. All i can say is that your product made the most significant improvement aside upgrading main hardware such like amplifier, dac, or speakers/he…
Sounds good…very very good!
Thank you for your message. The software upgrade is fantastic! So I have never been able to enjoy music before! Thanks for the support!
Kind regards and a good week wishes
This is a report of our first experience with Fidelizer.
I had heard of a few optimizer programs designed to improve computer audio sound, but I was sceptical. After looking around on the web I found an interesting product called Fidelizer. I decided…
Thanks for the explanation Keetakawee!
My wife and I listened well into the night… Your software does make an amazing difference. It’s like almost every last ounce of distortion has been removed! Colour me impressed indeed!
Fidelizer software is simply awesome for me – I nearly gave up on PC as a source, but now I am getting really close to my CD player – the sound is certainly more spaced out and softer, much less of that digital glare, with a bit of tweaking though…
I shouldn’t say this but it was the most well spemded 40 bucks I ever did in my system…
Well, the 100$ in the ODAC to, but 40 bucks is less.
But I’m worried about the purchase I’ve made because this seems work of the devil and I don’t want nothin…
Everything worked smoothly. I used Purist, and can definitely tell a difference (good) over Extremist Free.
Thanks so much,
Well I tried your FPro 7.0 last night, and it is all that people have said it is.
More low level detail, more depth, more space around people and sounds in the recording. You hear new details and the decay of notes in the recording space..
Got the Fidelizer Plus 7.3 software.Looking forward to hearing from you about future developments.I am very pleased with the results so far.It’s been a revelation.Thank you.
I have used Fidelizer before (F4 & 5) with good results, see copy of a post from JPLAY below. After more listening today F6 is clearly a further improvement. F5 Extremist did not really work for my system, but with F6 the Extremist option provides a …
Thanks Keetakawee. I installed it a few days ago on my JPLAY Control PC, and the background got blacker, the soundstage became deeper, and everything became more focused. Overall a significant improvement, I think.
So, I recently ordered another copy…
Thank you for a great software. I have installed Fidelizer to my Audio PC for JPLAY, and working great, the effect is more significant than changing Windows 2012 R2 OS to Core mode.
This time I am going to install Fidelizer to my Contr…
Thanks for the latest update and for Fidelizer in general, as it has made some amazing improvements in the sound quality I get from computer audio! 🙂
Here are some comments after using Fidelizer Pro this week.
Am using an Acer i3 laptop – 8 gig ram – win 8.1 with an IFi Power USB. I found that after a clean install the Fidelizer Freeware program sounded even better. Now with Fidelizer Pro the soun…
Hi, just to let you know I’m very happy with the program. It’s made and amazing difference.
Fidelizer 7 is fantastic. I have a very good analog system and have always tried to get my digital front-end to sound as good as my best lp’s. I am there now, 7 was the last missing piece.
I upgraded to the latest version of Fidelizer Pro last night. I noticed a definite improvement over the previous version. I read that the latest version fixes an issue where some core optimizations were not able to be applied. There is a definite imp…
Very satisfied with the result of Fidelizer/Win7/Asus i7 into Auralic Vega/Exact. It helped with the dropouts (non-existent now) and the sound is marginally cleaner in Flac and visibly more “solid” in DSD (in my system and for my e…
I think it is the best sound I ever heard with my Audio setting. Very clear background and close to perfect image (I assume there is no perfect with Audio since every new technique comes). Especially, when I listen big scale symphony like Mahler Symp…
Thanks for the update. Sounds terrific on Windows 10 with HQ Player.
Dear Keetakawee Punpeng,
I did some listening yesterday after installing FPro. My aim has been to find a better alternative to Mac/audirvana which I have used for several years. The two things I like about Audirvana are playback from RAM and shutting…
hi Windows X
it’s all right here
Fidelizer pro runs in my notebook and the music sounds almost perfectly
Greetings fron Buenos Aires
Hi Windows X
I am listening now to my music with Fidelizer 7 and I am in love with it!
Darker background and more natural vocals. I also noticed more air in the music and more focused sound stage. I can’t imagine myself listening to music from my PC …
Thanks Keetakawee, fidelizer works again, great as always-i missed it a lot these few days! Didn`t know i was addicted so far, now i know!
Fantastic your software! I use it precisely with a Copland Dac-215.
Thank you very much
hi window X
i am very happy with fidelizer pro.
thank-you for this great app.
Everything done well and sounding great!
Haven’t got time to listen and compare but I think it sounds more solid and detailed, with less grain , more dynamic, especially on the drums.
Thanks for the upgrade and I wish you a good New Year 2016.
Hi Keetakawee, thought I’d drop a few words on my Fidelizer Pro experience, for what it’s worth. I just replaced a 2002 HTPC with a laptop for the internet and a Hollis Audio Labs MS-3 fanless mini-pc music server with Windows 10. I’m using JRiver fo…
Yes very nice/you have done good work,I have been making some optimizations manually before I found Fidelizer. This is much more effective and easier (Thank you).
Anyway I like it so I will buy one for my HTPC,I will do this tomorrow from that PC…
Indeed working well and I pleasantly surprised at how much noise has gone away from the music…
Well done Sir.
Thank You, Keetakawee, installation was easy – the sound is absolutely great!
I use a simple Lenovo laptop/Windows10 connected via USB to my dac (modified Bow ZZ8 CD-player); internet-connection via WLAN (LAN would be possible too); I use Qobuz-Deskt…
Very pleased with the pro software, I’ve been listening to music all day here in the UK and I’m hearing improvements all round with sound. I’ve had it set to Audiophile with Network Render.
Easy installation. (I was a little worried).
Perfect, clean, clear sound!
Best Regards from Spain.
It works really well and I’m happy with it. Keep up the good work.
Thank you, great job for my “Control PC”
I noticed a big difference in outcome between the free version and the Pro, I love …
so I’ll spend a second order for my other computer “Audio PC” !!!
hi frd !
same causes, same effect… black background better lisibility especially in the highs, deeper image.
i rediscover the full potential of my rig…
thk so much for this huge job !
Just thought I would drop a email and say a big thank you for Fidelizer Pro.
I use it with Foobar2000, Process Lasso and Jplay on a stand alone Windows 10 PC. My DAC being a J Kenny Ciunas.
I had used the Free Version of Fidelizer, and l can happi…
Today, I reinstall the windows server 2012 and set SATA in AHCI. Bingo. The esata storage can start every reboot. Now I disable all the services in AO except WMI and I choose Extremist in Fidelizer Pro and JPlay in single pc mode. Now the sound i…
Hi all, 1st, Im new to this forum, 2nd Happy Birthday Keetakawee.
I came across this program via the trade in the UK with one of my friends asking if I’d tried it.
I hadn’t and as I’m one of those who has to mess, I decided to try the free version.
Still early days but my impressions so far has been very positive. The software works seamlessly and Windows has been stable so far. There is less digital glare in the sound, enhanced dynamics and micro detail but without affecting ‘mu…
Hi, finally is worth the effort, Fidelizer is rewarding, easy to use and also easy to notice the upgrade, when purist is awesome!.
Also I am done with Foobar, I have nothing against their app as a remote!
Only is need now, to install Asio drivers for…
Thanks for activating the software so quickly! I’ve been testing it out a little today and so far I like it! Thanks! 🙂
Thanks, I was already impressed with the Free version, this on to me sounds maybe less “romantic” but definitely more “fi” as in hi-fi – both run in “extreme” mode.
I use Foobar for music and VLC for movies or TV shows, a side benefit being that VLC …
Improvement on the audio pc is great, i have done a great jump forward. Thanks a lot ! When my new control pc will be ended, will sent you a new order. Good job!
I figured out how to get the best sound possible on Windows if you use Fidelizer and sound pimp both it makes the sound sound amazing. I broadcast on vaughnlive.tv/thedogpound and have been told I have the best sound on vaughnlive is so crisp and …
Thanks for the quick reply, I listened last night to the plus version, wow what a nice improvement over the free version, space and better defined leading edges on bass, the performers were more there, that “noise” that is there, alth…
Thanks a lot. It´s running and sounding really fine in combination with Jplay and Qobuz.
You do so much work in 7.4. 7.3 sounds on low level vs 7.4 I am can’t tell how I thanking to you. You are on right high-way.
Thanks, I don’t know what I do without you and Fidelizer 🙂
The Pro version works just great, big improvement on sound quality, and I am very very pleased 🙂
So glad I finaly got it, and it works so good..
Tried the network render setting so far,but will try MD with network support too.
Many thanks for the prompt response.
Fidelizer makes a very obvious improvement and I am so pleased with it that I will shortly be purchasing another licence for the second computer in our household.
Keep up the good work.
After installing Fidelizer Pro on my system, I was pleasantly surprised. SQ has improved and most important, I could play now ultra/700Hz/0.01sec with no interruption. Before installing it, there was no way to achieve that without interruption. 10/11…
I can’t play without him!! He is the missing link, to play music with the laptop.

Hello, fidelizer sounds great on my computer. Definitely takes the digital glare off and adds dimension to the wav files. Job well done, would like to stay in the loop for future versions, thankyou, regards, stacy.
Hi! Well, it works perfectly well. Instantly more transparent sound, clearer vocals. Good stuff) Keep it up!
It’s all installed and sounding fabulous
It works really well. Bravo!
WoW! I am floored by the Pro version! Digging in to the settings now. How can I thank you? Ferrari? Lamborghini? Maserati??
The enhancement of depth and the resolution of the complex layering of large-scale orchestral music came off stunning with Fidelizer.
We are flying higher than Baumgartner. In rare thin air of digital computer playback. Using Lampizator Komputer machine with Audiophile optimizer, fidelizer, 2012 core mode and the Bughead Emperor soft. This is as far as I dare to push digital playba…
Dear Windows X,
I have downloaded the application and installed successfully and find significant improved sound quality.
Thanks a lot.
I’ve installed Fidelizer pro 6.1 on my HTPC and everything is OK.
Audio is very good, as I’m using JRMC 20 as VDM driver and DVDFab plyer for playing DVD or Bluray.
This little media player has a very good video quality equal to JRMC with Red October…
Hi Win X:
A nice, very easily heard improvement. I would best describe it as a much more relaxed presentation, a layer of glare removed.
After two days of listening I can honestly say this is a fabulous upgrade…the detail is amazing…far more clarity in all registers…more snap and a lot more toe tapping from me…how much better can it get?
Thanks for the update, the program works fantastically with my hi fi headphone setup.
Dear sir good day
After a few days of listening to my new configuration, I am happy to inform you that Fidelizer Pro is doing a very good job at optimizing stuff. The sound quality improvement is more than subtle.
Mr. Phellipe Wattel, the CEO and cre…
After the trial, the better it sounds Deezer is essentially similar to rip the CD, then listen with jriver + Fidelizer yet. (But do not always listen to music with hi-res File I) autonomous Fidelizer Pro worth it. Works like to change my wiring, cabl…
Sound quality with Pro version is night and day comparing to free version. Pro version gives better focus and darker background. Great value.
I installed Fidelizer Pro and run the set up without any problem. Quite the opposite… I’ve never heard my audio system so clean and so musical ! Fidelizer Pro is a great upgrade and you’re a genius !!!
My PC is dedicated to audio, I’…
Thank you Keetakawee its great product and i’m really enjoying while hearing huge improvement in my system.
thank you for delivering so quick.
here I want to give you positive feedback.
I installed Fidelizer Pro without problems. I am very satisfied with the sound.
(Before I experimented with the FREE version)
My sytem is:
Dual core penti…
Now it works 🙂
Thanks for your excellent support and help.
Fidelizer makes the sound more clear. It was well worth a little trouble.
Person in charge
I purchased Fidelizer two the other day. I use it in ControlPC+AudioPC+JPLAY. I like it with high-quality sound very much.
Many thanks Windows X for the tips.
I have listened to many ‘so called’ audio upgrades over 25 years, including sometime spent myself in the high end audio business, and I cannot recall one as impressive as yours! I had a Japanese partner, who abando…
Thanks for sending, sounds fantastic, I love it!
tried out Fidelizer Pro the last hours in Purist mode. Realy fine music reproduction. The best I heard ever on my system. Read in the last 2 years many positiv Reviews and they described all changes in audiophile way very well. I ca…
Expected to get a more stable signal chain, what it does. Didn’t expect that it would make a noticeable difference in sound quality in my case, but it does as well.
Impressive, good job, well done!
Everything is working thank you. Is it my imagination or does the digital now sounds more analog like!
Just purchased your pro as I dud like your free software. It did seem like it added a lot more soundstage and high end detail but tended to make the midrange vocals a bit grainy or harsh especially on extreme. I found audiophile setting to be the mos…
Thank you Keetakawee!
There seems to be a difference. The big picture doesn’t change at first listening, but there are changes in the details.
There is more air (or room information), and the instruments are focused better, having more contour, or mo…
Initial results are very positive. The level of detail from recordings is noticeably improved but more importantly to me is the more relaxed presentation. Still plenty of attack but less fatiguing than before. I listen to my music on Denon D7000 h…
Lucifar I’ve had a conversion — Fidelizer free definitely makes my music sound better. It’s the audiophile thing, the sound of the music.
But the PLUS! It makes me enjoy the music for itself, never mind the audiophile thing.
Thank you!. My first impression while listening is of greater fluidity of the music. I’m using in my office system a Vaio PC/JRiver21. I’ll come back for further advice from you
I am actually quite happy with the performance so far.
Have been testing Fidelizer pro now for two days and I can only say that I am impressed. I am mainly listening through a highly revealing headphone (audeze lcd) system, which was already sounding pretty good, but your software gave a v…
Dear Keetakawee Punpeng,
Thanks for the full copy of Fidelizer Pro 6.8, the program works perfectly on my machine. This Fidelizer Pro, just as you said, it improves imaging and clarity of the sound also reduce glare in digital audio. I combined JPlay…
Brilliant, thanks. Really enjoying the program by the way, I’m using it with process lasso now to kill off all other processes. Great stuff.
Thank you for the software! It changed my system from ordinary to high end! Truely amazing!
Edo van den Broek
Upgrading Fidelizer to Fidelizer Pro on Control PC of Jplay has apparent impact on sound, more depth, more air, and more contrast. I think it is an essential software for PC audio, and one of the most cost-effective investment. It is w…
I have been using Fidelizer with Jplay for some time but Fidelizer Pro really makes the difference, i’m quiet happy with the result, the sound of my system really changed for the better.
Thank you so much. Your software is very wonderful. I’m using it with Karaoke Extreme and it sounds very great in my system. Thanks so much again.
Super super Thank you. It all comes down. Thank you for helping me. Finally I can enjoy the music.
Focus and definition improved with an added bonus; a slight midrange hardness I have heard in JRiver was now gone.
Dear Keetakawee Punpeng
Thank you very much for your excellent product “Fidelizer Pro” you sent to me. After downloading the file, I immediately installed it on my audio PC, part of my dual PC audio system. It has worked miraculously and I have f…
Great program! I love what it does to the sound.
Thanks for a great product! It works really well in audiophile/renderer mode, together with Roon-Jplay-Ifi-Lyngdorf2170 🙂
Fidelizer Pro sounds incredible on Windows Server 2016 with AO! More of everything: silence, vibrant sounds and very nice sounds of instruments. Great. Thank you!
All the people interested in highend digital reproduct…
All’s in perfect order.
Similarly as before, the SQ has gained in the volume and quality of bass, better separation of instruments, clarity and depth.
Thanks a lot.
Dear Windows X,
Thanks for the update 6.8. Installed and running. UAC disabled. Very good sound, low-level detailing is clear and soundstage is wide and deep.
I listen to TIDAL via Chrome browser. Sound is output to ASIO BRIDGE ==> to JPLAY ASIO driv…
Hello there! Thanks for your work. This small software is really great! )) The most I like in pro version is autorun on Windows startup. Everything works fine: no lags or hardware conflicts or any other issues. I use netbook with 1,33GHz Intel Atom o…
Many thanks, everything works much better, now I can enjoy the music without worrying, everything is in place and the H.D. Sound analog. You are a genius, thank you very much again.
I’m playing well since using fidelizer, the scene is wider, more space between instruments and high / medium frequencies more refined, but my little English not allow me to write better.
I’m using a fanless PC reserved for the digital music, cu…
ITS sounds better then before I really don’t know what you guys doing this.
Fidelizer PRO makes it sound more real and clear. The bass better now, it’s more powerful and accurate. But most importantly the overall sound is a little less “digital” which enhances my musical experience.
I’m listening now to the 7 it sounds so much better, You make my day thanks and a fantastic weekend.
( : Henri Jimmink : )
I installed Fidelizer Pro last night and i could say that if brings a significant improvement on the sound of my system. Coming from the free version i did’nt expect the improvement to be compelling. It open up the sounds with bags of det…
Thanks for the great product; I’m very impressed with the improvement it’s made (and even more surprised!) at the impact it’s had on the SQ of my system (especially Purist mode).
Very great Fidelizer Plus..regards from Firenze Italy 🙂
Wow.! Very nice upgrade from earlier version. Sounds better than my LP playback now
Thanks for the update. I love your program. It has been perfect for my server. What a great idea to maximize the value of what one wants to do with Windows.
Sounds really good streaming over Tidal HiFi. I was skeptical, but it is definitely an improvement; smoother, more transparent and analog sounding. Listening through these, and they’ve never sounded better. Don’t know how you did it, but great pro…
The sound is amazing, I have to say I couldn’t be happier with fidelizer.
I’m using a Windows 7 PC with a SOtM tX-USBexp USB PCIe Card sending audio via USB to a IFI IUSB 3.0 which then sends audio to my Emotiva DAC. I was previously using asio4all a…
Thank you. Installed and did the recommended foobar2000 settings. It sounds incredible !!! Such a big sound with SQ enhancements everywhere. Closest thing to “being there” that I’ve ever heard on headphones. I run Beyerdynamic T1 headphones with a Wo…
Tx Man, Difference is night and day
I been enjoying the Plus and the difference between free and Plus is day and night!
I tried the latest 7.3 software in audiophile mode. Install was flawless. I had previously run the fidelizer in purist mode with the multi core selection off as suggest since I some problems with purist initially. I was concerned since I use the my m…
Finally got the Pro version… Amazing improvements all round, but in my system specifically, bass slam, note distinction and the initial note attack all improved quite remarkably (sorry, I am a musician and I relate everything to notes). I also have b…
I run Fidelizer Pro + Asset UPnP Server + Linn Kazoo on Windows 10, It sounds greater than J.River Media Center 21, the background is very dark, instruments sound separately and clearly, I like it.
Oh my gosh I just installed and restarted my system. It is now so much faster and JRiver comes up much faster and cleaner. Thanks so much!!
Thank you for sending me my new fidelizer pro installer. Fidelizer creates stunning sound, its like adding another device to my stereo system. I will not want go back to listening again without the works of fidelizer. Excellent work!
Sounds good, obviously so much improvements. Listening to music LCD3 is awesome. Music is much more matured up. I will follow up for future updates. 2500 Baht is worth it for the music, really good.
Great product! Really makes more different to the sound with my setup than ‘replacing all the cables’ Very pleased!
This is simply amazing. I never expected such improvements at this level. The performance is much more quiet and relaxed now. No more harshness to my ears, even with more clarity. It improved my system more than changing cables.
Hi Windows X,
This is some brilliant stuff! Music seems to come from a darker background, with a more realistic tonality. Bass lines have improved significantly, each drum beat is tight and precise, overall bass is much more punchy and energetic. To …
After running Fidelizer Pro*(non-free version) optimisation, I was able to lower my Mutec MC3+USB’s Asio buffer down to 64 Samples and USB streaming mode set to Minimum Latency. No audio dropouts experienced(which wasn’t possible without fidelizer).
Thanks Windows X,
Yes fidelizer Pro is doing what I want and I’m able to just sit back and enjoy the music.
Before I upgraded my PC from w8 to w10 I had manually disabled many services myself to optimise for audio but this was always a bit of a lotte…
I love the sound of it so much I do not want to be without it. I was using it with JPLAY the sound was wonderful.
Dear Khun Keetakawee,
I am just listening to my fully Fidelized 2PC setup and the sound really took a leap forward. It sounds incredibly detailed and clear, specially brass instruments. What a great piece of software.
I can hardly wait installing it …
I am running fidelizer plus in win server 2016 along with AO optimizer and the final result exceeded my expectations! Fidelizer plus gave to my system a vivid and truthful character, more volume and weight in the lower end, highs witho…
a big “Thank You“ to you.
To listen the music without Fidelizer is not good, because I know it from the old PC until he get broken.
hello again, I just wanted to say your pro version is awsome!! I just about gave up on computer audio(trying for 2yrs to get it right) music from my system has just come to life compared to before.As I enjoy album after album!
