    Nimitra – Computer Audio Server


    Fidelizer Nimitra B&W 2


    Fidelizer has been improving computer audio solutions for audiophiles since 2012. After successfully solving digital audio problems in audiophile and pro market worldwide, it’s time to launch our first physical product “Nimitra”, the cherished dream for audiophiles.

    Coming from an audiophile who searched for highend computer audio sources before, Nimitra is a computer audio server that you can truly enjoy the music as highend sources and easy to use as plug and play product.


    “I need to build ones they can enjoy without learning about computers”


    It’s a lesson from interacting with Fidelizer customers who has no computer background before. With data from researching and developing a few local products in Thailand, Nimitra is the result of trials and errors as ultimate turnkey streaming audio solutions.


    The results were unusually planted and rhythmically coherent for a file source, with greater body, weight, musical coherence and structural organization than I’m used to from file sources.

    Roy Gregory, The Audio Beat

    A friend from Asia, with an impressive high-end audio setup, didn’t miss his Aurender W20 anymore since acquiring Fidelizer’s Nimitra; he actually sold it. At ten times the price difference, it surely opens up a Pandora’s Box.

    Matej Isak, Mono and Stereo

    The sound quality is crisp, very dynamic, very detailed, and the sound is natural, big and open. Especially impressive is the separation of instruments and voices and the believability of the soundstage image.

    Richard Varey, TNT-Audio

    Extended listening to the Nimitra via the Oppo consistently brought me the best sound, though I can’t fathom why that should be.

    Kalman Rubinson, Stereophile

    The Nimitra is transparent in the ways that are good—letting the signal through seemingly unmolested, without being transparent in ways that are not good—lean, bleached or neutered. I think Punpeng has largely achieved his goal of a turnkey operation.

    Larry Cox, Positive Feedback

    Overall detail and focus were first-rate with the Nimitra. In some ways, the Nimitra reminded me of the Playback Designs Syrah Server in terms of its excellent playback qualities.

    Steven Plaskin, AudioStream

    I’d take the Nimitra over the SOtM 1000D I reviewed a couple years ago in a heartbeat. It’s cheaper, more user friendly, more flexible and if aural memory serves, sounds just as good if not better.

    Windows 10 Nimitra Edition Platform


    Windows 10 comes with many features unrelated to audio solutions. Some may tweak OS to disable unused features. Nimitra handles this matter at roots by removing all non-audio features from installation itself, greatly improve audio performance by cutting almost everything in half.


    Fidelized Windows 10 Pro debloating performance


    There’s also special version of Fidelizer as dedicated CAS platform, applying more optimizations that be to put in Pro version and greatly reduce process time that can ready your system in about 30 seconds from power on. It’s the most solid audio platform in commercial products today.



    Affordable yet uncompromised


    Fidelizer already does fantastic job as software solution so building Nimitra music server will be something that can be used as a reference for future models in computer audio industry. It all started with the design for the best product and see how to make affordable ones without breaking its principles.


    With over 10 years experimenting about computer audio, the best designed for computer audio machine should follow these principles below:

    1. No moving part – Moving part causes vibration affecting the accuracy of electricity’s transmission.
    2. Low power consumption – The best way to reduce pollution is to consume less power not adding more filters/isolators.
    3. Resonance control for chassis – It’s often overlooked in digital audio but resonance of chassis affect digital audio a lot too.


    Fidelizer Nimitra Case Inside


    As a result, the finished hardware design has the following specifications:

    1. Fanless machine – No fan, no vibration from fan and no noise pollution in listening room.
    2. mPCIe SSD for OS storage – No moving part, no vibration and no data/power cable for signal degrading.
    3. Intel Celeron J1900 2.0GHz CPU – Quad core, low power consumption but powerful enough with 2MB L2 Cache.
    4. Kingston DDR3L 4GB Memory – It’s a hard decision between lower CL with DDR3 or lower voltage with DDR3L but lower voltage is better.
    5. Direct 12VDC input power supply – Feeding power directly to the board reduces noise and pollution inside.
    6. 3.5mm aluminium alloy frame – It also comes with only 3 pieces having less frequency shift with audio-grade isolating feet.
    7. Built-in WiFi/Bluetooth – You can setup WiFi and Bluetooth speakers to use with music server platform.


    From long research, this is the best hardware design that can compete all computer sources in market today regardless of the price. People believe getting powerful processor will improve sound quality but that’s not necessarily true since it also increases pollution and interference.

    For audiophiles without computer knowledge, it’s very important to have remote access for cases like installing drivers for new devices after purchasing Nimitra.

    I have been using my Nimitra server and Nikola PSU for about a week now. Initial impression is that I do not appear to be missing anything with the sound.

    The sound is similar to that which I get with my Linn Sondek turntable with good mu…


    Hi Keetakawee, I received the Nimitra yesterday and I want to congratulate you on a wonderful streamer.  The set up was a breeze and the sound is fantastic! I spent 3 hours last night listening to music, what a treat!

    Murat Ucer

    Hi Keetakawee,

    Thanks so much for all your trouble! Everything seems to be working well now. I did unplug the USB lead to the DAC, so I could compare the Aurender and the Nimitra, as you had it playing stably..

    I can’t get JRemote to register, but th…

    First I have to thank Mr Keetakawee Punpeng for all of his brilliant support he really takes care of his costumers!

    Hi guys.
    I wanted to jump in here as a customer of Nimitra.

    Firstly I have to say the product is top shelf. I have never heard my system sound so good and am thoroughly enjoying the benefits of this device. In fact I have sold a Sony HAPZ1ES player t…

    Steve Andrews

    Hi Keetakawee

    The Nimitra is sounding very good indeed. With the usb drive plugged into the USB 2.0 input, the sound is much more cohesive and musical. It also works well with Roon – very smooth interface.



    The Nimitra sounds incredible, even on my humble setup. I know it’s a cliche, but I’m hearing things I never heard before. Instrument separation is orders of magnitude better than with my laptop. Vocals that were muddy are now crystal clear. List…

    Seth Shapiro

    We LOVE the custom Fidelizer Nimitra. We run Roon to HQ Player on the MacBook Pro, then ethernet to Nimitra HQ Player NAA. We upsample PCM to 88khz, unless it is higher res, and upsample all DSD to DSD 128. With the PS Audio DirecStream DAC 24-88 khz…

    David Levinson

    Hoi Keetakawee,

    I thought I will give you an update of my adventures with Nimira and Nikola. It runs very stable. Some times after a driver switch a DAC clock locking problem occurs but that is fixed by a restart or some more switching.
    Roon runs ver…



    My Nimitra has now been on playing a mix of music for 200 hours and its sounding brilliant, quiet background, bags of detail, wonderful bottom end. This is extreme value for money.

    Kind Regards

    Beautiful couple in both sound and body. Sound improve in all three range. For update, the improvement of Nimitra upgrade version from Nimitra original version now is more than 50%!

    Nattachai Srisawat


    I’m using the Nimitra now as Roon endpoint. Setup was very simple. Out of the box I must tell you it sounds magnificent. Roon is running on my custom PC.

    Thank you. You have created something very special my friend.


    James Daras

    Many, many thanks!

    I am listening to the Kazoo JPLAYSTREAMING on HUGO through HIFIMANN 1000v2 headphones and the sound is truly magical!

    I am sure I will still need some handholding later on but for now everything is quite wonderful.

    You are obviousl…

    Colin Campbell

    Thank you so much. The display is now working fine and the music has never sounded better. Great support.

    Song Soon Onn

    After playing my special order Nimitra, It is clear that it is the best of the best music players out there, regardless of price and I am confident of that as I heard streamers from big names that cost more than 4 times Nimitra and don’t sound as goo…

    Moussa Obeid

    Hi Keetakawee,

    It’s about a week ago that I have the Bifrost dac back and I can tell you that the Nimitra is playing fine with the upgraded dac.
    I can play music from the hdd storage and from JPLAYERstreamer. The only weakest feature is the Linn Kazo…


    As NAA with HQPlayer and a second pc, the Nimitra sounds really exceptional. Congratulations.

    Maurizio Lombardi

    Nimitra/Nikola is a clear winner in my system; this innovative system represents a step change in performance. Compared with my ‘tuned’ laptop audio-PC, Nimitra/Nikola is clearly the better music machine. Higher level of detail, transparency and tona…

    Kjell Nedrebo

    Hi Keetakawee,

    I am now back home enjoying the music with Nimitra.

    I am very happy with Nimitra, sonic performance is great – thought you’d want to know.

    Thank you for your work for me.



    Hi Keetakawee,

    I got the Alpha USB driver installed and listened using jRiver Media Center. Wow! It really is a superior sounding rig! I will listen for several hours before upgrading to the Nikola power supply, but I am already very impressed!


    Grant Jacobson

    Good news. The sgms does sound superb. But nimitra is very close. Too bad we haven’t had more time to compare. We only compared the Shirley horn song playing now. In a blind test,  I may not be able to differentiate sgms and nimitra. Sgms maybe soun…

    Adolphus Minu

    Powering Nimitra and the exaSound e38 DAC with the customized Nikola power supply indeed sounds GREAT!
    I’m in complete agreement with Steve Plaskin’s assessment of the Nikola / exaSound DAC combination; it is transformative! Nikola transported the so…

    Hello Keetatawee,

    I have received the Nimitra in good order from DHL.

    You have indeed solved the problem: the NAS can now be seen in the network and also be added as source for JRiver library import. The Nimitra is connected to my dac and already pla…
