Fidelizer Nimitra Computer Audio Server

Nimitra is a computer audio server based on streaming solutions using JPLAY Streamer and Asset uPNP. You can control Nimitra from just connecting device to home network, install mobile app like Linn Kazoo and play audio effortlessly with the most accurate PRaT and neutral sound.

Music Server

Nimitra can work as music server by connecting USB storage and USB DAC, join the device with your network, and browse for your music collection using Linn Kazoo or any uPNP application of your choice.


Nimitra can act as library server in place of NAS by connecting USB storage, join the device with your network, and stream audio to network players. It also supports DSD streaming and Internet Radio too.

Network Player

Nimitra can transform conventional USB DAC into Network Player by connecting USB DAC, join the device with your network, and stream audio to Nimitra as Roon ready and HQPlayer NAA device.

Recommended media control software:

Windows: Kazoo, Kinsky, foobar2000 + foo_upnp
Mac: Kazoo, Kinsky
iOS: Kazoo, Kinsky
Android: Kazoo, Kinsky, BubbleuPNP (TIDAL Support)

You can also install RoonServer, HQPlayer, or other audio software of your choice to use with this ideal platform too. What about USB audio driver? Nimitra has USB audio drivers pre-installed so you can plug and play USB audio devices without installing drivers manually.


Fidelized Windows 10 Platform

Nimitra runs on very lightweight version of Windows 10 Pro, Fidelizer Audio removed all non-audio components in Windows 10 Pro, greatly improved audio performance with smaller footprints.
Also Fidelizer as dedicated CAS platform has been improved, applying more optimizations which greatly reduce process time that can ready your system in about 30 seconds from power on. It’s the most solid Windows 10 based audio platform in commercial products today.

Affordable yet uncompromised:

With Fidelizer Audio's over 10 years experimenting about computer audio, the best design for a computer audio machine should follow the principles below:

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

As a result, the Nimitra audio servers hardware design has been finished with the following specifications:

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

Be sure it’ll be the best hardware design that can compete with a few times more expensive products in market today.

Direct support with Team Viewer

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.


Nimitra Classic’s features:

-Same software features and optimizations as Nimitra2 version
-Cost most effective solution for sound quality / features / services
-Compact 1.5mm aluminum thickness chassis for small space
-Cost effective motherboard design with high precision event timer
-Trusted industrial quality components with high reliability


Nimitra Classic shares the same NimitraOS platform and optimizations as Nimitra2 for best sound quality. Only difference lies in hardware design but we still choose the best one with true high precision event timer implemented where most affordable Linux servers don’t have it.


Nimitra2’s features:

-Aluminum chassis improving resonance control and heat dissipation
-High quality low ESR solid capacitors upgraded in motherboard
-High quality MOSFET from Japan in motherboard’s power supply
-High precision clock upgraded on USB/Ethernet/HDMI ports
-SLC SSD grade storage with highest quality of SSD design
-Premium RAM quality for better audio performance
-Motherboard and chassis has vibration absorber/isolator material


Nimitra2 is the second generation of Nimitra series with the best possible hardware upgrade including hardware modification on original Nimitra based on custom highend version.
