Are you computer audiophile? If so, Fidelizer will help you enjoy the music on computer even more.

Nimitra – Computer Audio Server


Nimitra - Cover


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.

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.

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.

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.

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.

Fidelized Windows 10 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.



Direct support with Teamviewer




For audiophiles without computer knowledge, it’s very important to have remote access for cases like installing drivers for new devices after purchasing Nimitra. You don’t have to worry about being left behind after purchasing Nimitra with Teamviewer access built-in for professional support.

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!

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.

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…
