Relaxed dream of cherished audiophile

When I received DHL parcel from Thailand I've been suprised by sizes of Fidelizer Nimitra. It's really small device, even I may call it "miniature". Terse frontal panel with only one power knob, austere black colour, light weight (2 kgs). And full enigma with name despite on my numerous attempts to put on the rack a Google seaching machine.

Ok, this secret was opened to me by developer of Nimitra, also known to computer audiophiles as creator of Fidelizer audio optimizator for Windows, Mr. Keetakawee Punpeng:

"I chose Nimitra as a word from one of popular traditional Thai music "Tri-Nimitra".
Nimit means "dream" and tra comes from 'tra-trueng', something like captivating, cherishing.
So, Nimitra means "cherished dream"."

3 in 1, main features are: Music Server, Streamer, Network Player. So you may use Nimitra as simple Transport of USB Stick Memory, it's exactly what I mostly did during the striking of laptop's keyboard.

"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." (from site of developer).

Back panel equipped by many various connections was nameplated "Demo" (my device was numbered as "4", I could see it during settings). Well, not mine favourite figure, but I don't like to be so boring perfectionist.

You may add keyboard, mouse, display and use it as standard desk-top PC, side USB connectors will be suitable for it.

Ful set of supplied items was predictable: Nimitra server, power adapter with standart computer cable, 2 antennas "whip" type, user's manual.

I didn't install any driver for my AMR DP-777, developer already did all routine job collecting drivers for various devices. Do you impress enough??? It's first goal voting for purchase of Nimitra by non-computerly advanced audiophiles.

 After about 30 seconds of turning on device will make a greeting saying "Fidelizer Nimitra is ready".

One of the first my question to Keetakawee was "What is inside of your magic box?"
And he promptly dropped me this photo in Skype.

Most of my readers will look on this photo with same level of knowledge as mine, so I will also copy description from Fidelizer's site:

"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, I finish its hardware design 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 and I chose the latter.
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 Wi-Fi and Bluetooth speakers to use with music server platform."

The rest information regarding construction you may find below in Specifications and on site as well.

Second goal for the gentlemen which are not so much familiar with modern computers - direct support with Teamviewer.

That will mean:

"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." (from site of manufacturer)

I have to make a Confession here: I consider myself quite advanced PC user, but received technical support was ample, qualified and honest. Of course if you will be ready to give access to your home network to Keetakawee.

Thus, dear gentlemen, nobody will leave you with computer-network problems alone, Mr.Punpeng will fight till the last breath to solve the issues. Just believe my own experience.
  Few hints from my side grounding on my 3-weeks experience with Nimitra:

- Look on this photo. Your DAC should be connected to top blue, marked as "USB Audio" on picture above, USB Stick Memory or HDD with musical files - to lower blue (marked as "USB 3.0").
You may use also USB 2.0 on rear panel for USB and HDD, but sound can degrade a little bit. And don't use USB inputs on side panel, remote software will get significant delays and even can stuck.
 - Footers under Nimitra. I used 3 pieces of my own manufacturing and I could hear the difference.

- If you want to change files on USB Stick - don't switch off Nimitra! Just unplug, make changes on Stick and plug it back into the working Nimitra. Server updates library of musical files every 30 seconds.

I used mostly KAZOO programm for remote control of musical files (it's Android soft, can be found on Google Play Market). One significant moment which I found working with it - tags. All tags should be filled properly otherwise you will get a great chance to get a mess on the screen of your remote device. Kazoo is a little bit weird programm, but you will adopt to it for a few days.


First of all, Nimitra had not exception as per my own experience: 100-150 hours of "break-in" process should be granted. Otherwise its sound may not impress you. It's quite easily to arrange using Kazoo. Open "All albums" file and touch in sequence all required albums. Just put your finger on musical album and hold it till it will be highlighted. Thus you can compose music for required time period. If you want to use same album for breaking-in - choose it several times to cover required time of playback. Compilation can consist from files of various formats, for example, I mixed up 16-44.1
with 24-96 (FLAC) without issues. Bingo!

Nimitra skillfully shows atmosphere of jazz club on legendary record -
"Art Blakey 1954 A Night At Birdland" (Blue Note Records). Announces of Pee Wee Marquette, solid blowing of Clifford Brown's trumpet, firm sound of Blakey's drums, background noise of club, everything what was soundshooted by Rudy Van Helder (R.I.P., Man!).

Cyrille Aimee from album 2016 "Let's Get Lost" has such characteristic properties similar
to the one of my favourite female jazz singer - Stacey Kent. Nimitra played it in so comfortable manner of intimacy of singing, I couldn't resist and gave highest numbers in category of emotional involvement.

Great performance on Danielsson Neset Lund 2016 "sun blowing" (ACT Records) permitted me fulfully to be enjoyed by the record, ACT is one of few recording company with good balance between excellent quality of records, smart music not rolled into madness of free forms and impressive list of artists. Fans of Nils Petter Molvær, put your eye ear on this job!

Unlimited energetic and real hit melodies on Filou 2016 "The Headphone Sessions" made my audition so joyful, transparency of Nimitra was highly helpful.

Soundspace building of vocals on track "Because" (19) was imminently gorgeous.
Basses were taut and tuneful on tracks "Growing Up" (12) and "Thlon" (10).
Mix of real and virtual instruments on track "Dead Already" (07) sounded detailed, with rich textures.
Musical vocal peaks on track "Con Te Partiro" (03) passed without limits.
Naturalness of grand piano on track "Fantasia op 49" (06) was amazing.

Sound resolution of Nimitra stays on high level of very good compact disc players, all nuances of sound textures will be achieved. Server will apply a strong resistance during so called "blind test" for sure.

Server produces comfort sound with great liquidity close to analog sources.

Few advices which I received from Keetakawee regarding opportunities for sound improvement:

1) Nimitra supplied by standard power adapter made in China. If you are ready to invest 3-4 green Franklins into linear PSU - you have a great chance to get more sound. PSU should be able to arrange 12V and 3A.

And yes - Keetakawee is working now for PSU Upgrade option.

Quotes from our messaging:
"Coming from stock PSU with Nimitra to affordable linear PSU at under $300 range in market,
it should provide 30-50% improvement for general audience IMHO."

2) What is power supply of your ... network router? Quite unexpectable question, neh? Well, replace it also by linear PSU. It will work as Nimitra's creator insisted. I didn't check yet but I will do it later and reflect it in update of present review.

As conclusion

Transparency. It is the main feature came in mind if somebody will ask me about Nimitra sound.
Server is able easily to show a difference between artists, label, recording rooms, used recording techniques on high level.

Comfort. One of the biggest "pro" is even reflected in the name of my review. Gold medal on the championship amongst the laziest audiophiles in the world is your!

Price. Not cheap, yeah, but most of competitors cost more & much more till lunatic XX XXX USD.
When I tried to calculate the price for so called "Musical desk-top PC" I overlaped the sum of 1 500 USD quite fastly. Ok, that was been together with HDDs, but it was simply PC without any optimization! In case with Nimitra you'll buy device which is very close to formula "plug and play" if to factor out developer's support. Also cost of used software (Windows 10 Pro + Fidelizer + JPLAY + Asset uPNP) is more than 300 USD. And don't forget about money back!

Nimitra succesfully eats any audio formats (even including newest MQA despite it's not described on site!), so you rather will get restrictions from your DAC like in my case with DP-777, where the nowadays DSD is not supported.

In case if you will upgrade Nimitra by separate linear PSU - don't forget to replace fuse (if suitable) and power cable. I believe such manipulations will add some coins on the bowl of audio justice. Choose the right bowl!

You may try to find something better for this money. My hottest regards.
