Nimitra2 Computer Audio Server review on Positive Feedback by Marshall Nack

 in Review

 

Nimitra2

 

Finally, the first Nimitra2 Computer Audio Server review is published. It was reviewed together with Nikola2 Linear Power Supply and EtherStream Network Switch after reviewing previous products. This review feels like the main dish has finally arrived after serving appetizers.

I was pleased to hear that Mr. Marshall Nack decided to review Nimitra2 server after reviewing EtherStream. It’s an honor for Nimitra2 to be the first streamer being reviewed by seasoned audio reviewer in highend audio system.

Positive Feedback

Believe me, I didn’t hear anything like this when the Mac was in-stream. I was always aware of deficits in tone, timbre, texture, and dynamics. To put things in perspective, if we were to use my much more expensive CH Precision transport as the reference, I’d say the Mac with Fidelizer ancillaries reproduced about 60% of what’s to be had, forcing me to assign it to the low-end class of gear. The Fidelizer Optimized Solution with Nimitra2 server filled out the big picture to raise the percentage to around 85%, and streaming vaulted into issue-free mid-fi. Now I could sit back and be comfortably entertained as Cyrus Chestnut tinkled the ivories.

It’s very hard to pick excerpt from this review when there’re so many good good aspects about Nimitra2 product. Please read his full review and see how he feels about Nimitra2 as a genuine highend audiophile and happy listening. 🙂

Nimitra2

 

Here’s a new feedback today from original Nimitra owner who upgraded to Nimitra Signature and then Nimitra2.

Keetakawee,

I’ve spent the last few weeks with Nimitra2 testing lots of music and comparing different sources. I may have told you that in the past I used Nimitra as source but with the ultraRendu connected to the DAC as streamer (I think that’s right – I get confused streamer-renderer-etc). Network is isolated through EtherREGEN (Uptone Audio) and I use all LPS for all digital including the NAS. All PS Audio – DC DAC, PW SACD transport, BHK signature Pre and BHK signature 300 monoblocks. Speakers Harbeth 40.2 anniversary, all Audience Front Row cabling. Roon and JRiver

A while ago I had Conrad Johnson ART Pre (lots of 6922’s) and the original ART monoblocks (lots of KT 150’s) feeding Revel Studios with Muse model 192/10 DAC/transport source combo in a 125 year old house with beautiful old 1-1/4inch pine paneling for walls, high vaulted ceiling and floor that produced virtually flat frequency response across most of the audio spectrum. The soundstage that system/room combo produced was high, wide and deep with pinpoint accuracy of instrument locations, especially voices locked dead center. Music was everywhere and the low end was rock solid. As you might guess I’ve been trying to reproduce that experience after having moved on from the house and the CJ/Muse equipment.

When I first started serious listening to Nimitra2 I left it connected to the uR as I had the original. I had done some comparisons of uR vs USB direct in the past and preferred the uR. I finally decided to try N2 USB direct following our conversation below. I’m pleased to tell you that my soundstage is back. Room acoustics I believe are restricting depth behind listening position but the precision of instrument position, voice, width, forward depth and height are all there again. Surprisingly, the low end is, if memory serves, even more defined and clearly driving the music. Important to me as well are piano notes without ringing and N2 does an excellent job there.

I’ve switched between asio and wasapi with Roon and have a slight preference for Wasapi. I’ve also found – and it’s a surprise to me although it shouldn’t be – that JRiver with direct kernel streaming is clearly superior to Roon but without the convenience and access to Tidal/Qobuz.

We’ve had a fairly long relationship and I’ve been the beneficiary of your progressively better engineering and development across multiple products. I’ve been an avid audiophile for many, many years and believe my ear to be quite well trained. I can’t and frankly won’t repeat all of the cliché accolades one might find in the audio periodicals but I will say it just sounds great. Thank you.

Sincerely,
Jim Daras

It’s been a long journey since the first time Nimitra came out and I’m glad to be able to help original Nimitra owners seeing improvements to latest work at its finest. 🙂

Added Nimitra Classic + Nikola Classic + EtherStream feedback from Michael Neely

Nimitra Classic - computer audio server

 

Here’s another feedback today from a client who ordered the most valuable combo Nimitra + Nikola Classic combo with EtherStream.

I really like all the features of Nimitra. It is a perfect adaptation of a computer just for music and streaming. No other clutter. I am thinking I will explore Roon eventually since it is already supported.

Best regards
Mike

Although Fidelizer is known for developing very affordable highend products, they’re also designed to be very simple to use. I’m happy to hear this trio delivered clutter-free experience. 🙂

Regarding Roon issues with some hardware devices including Nimitra in update 1.8 build 880

 in News

UPDATE: Roon 1.8 build 882 is released now and it’s working fine with Nimitra. Please contact me for updating Roon to latest version and happy listening.

 

Hi. Today Roon launched new update 1.8 build 880 and some Nimitra users has the following issues

  1. Database is corrupted (which it is not but build 880 can’t read database for some reason)
  2. There’s no audio device in Audio section at all

These issues are from changes in build 880 that doesn’t work properly with some hardware and it’s widespread issues through Windows/Mac/Linux platforms. You can check Roon Support section for more details about 1.8 build 880 update issues.

For current workaround I can rollback Roon core to version 1.8 build 831 which is stable with Nimitra. You can download Roon 1.8 build 831 from the following links below to control until they release an update that fixes these issues.

 

Roon 1.8 build 831: PC / Android / iOS (Not available outside App Store)

 

iOS devices can’t install older Roon version so only PC and Android can perform rollback for now. Please contact Fidelizer support for setting up Roon 1.8 build 831 rollback. You may consider using other apps like mConnect / Lumin / Kazoo to control Nimitra also.

Introducing Nimitra2 / Nikola2 as second generation of computer audio server and linear power supply

 in News

 

Nimitra2

 

Today is the big day for Fidelizer. After years of preparations and refining products for second generation, Nimitra2 and Nikola2 are finally ready for production which are projects I’ve been working for 2 years already.

There’s so much going on behind the scene since last year. As I also have clients ordering custom $5-7k server project since the first Nimitra. I always thought it’d be great if we can build  a product having performance that resembles custom highend server for half price.

With Classic series, it helped me realizing my dream to make highend audio performance affordable at $995. There’s also very good cost effective Nikola Classic at $395. This will keep Nimitra affordable and I can focus on taking second generation to next level.

I planned to launch them last year but could not make it to production stage due to covid situation which affect many companies worldwide causing long delay. I’ve been selling Nikola Signature with Nikola2 circuit board for over a year now, waiting for Nimitra2’s completion.

Now that I can finalize Nimitra2 design and production line, it’s time to embark a new journey. Nimitra2 will pair up nicely with modern DACs in market with custom made chassis, optimized as a streamer to deliver performance based on CD transport with Esoteric’s drive.

 

Nimitra2’s Features (As upgrade from Signature):

-Custom aluminum chassis design for better resonance/vibration control and heat dissipation
-Motherboard and chassis has vibration absorber/isolator material reducing vibration to motherboard
-MOSFET in motherboard’s power supply circuit is upgraded with high quality one from Japan
-All clock modules in motherboard are now upgraded improving sound quality on USB/Ethernet/HDMI
-Capacitors in motherboard are tuned with better resolution and details extraction

With all new improvements focusing on improving purity of signal and reduce interference, I can hear music flowing with richer ambient and micro detail and feel closer to music with newfound improvements on Nimitra2.

MSRP price of Nimitra2 is $2495 USD. For original Nimitra and Nimitra Signature owner, you can send your original unit to upgrade to Nimitra2 at $1,100 for Nimitra and $600 for Nimitra Signature. This upgrade should be a great value for existing customers to enjoy music better.

 

Nikola2’s Features (As upgrade from Signature):

-Input capacitor is changed to dual capacitor circuit design improving power handling
-Diode is upgraded with higher output current to handle devices like Roon Nucleus+ better
-Capacitors are tuned for better transparency and micro detail without sacrificing musicality

With new changes and improvements on Nikola2, it helps music flowing with Nimitra more coherently with timbre and PRaT done right to make music both enjoyable and believable. This can apply to any device Nikola2 powers also.

MSRP of Nikola2 is $749 USD. Nikola2 has a new circuit design so upgrading with top up price is not possible. Also, most changes are about handling some cases better so Nikola Signature will deliver similar performance with some sound signature changes.

 

Fidelizer will provide free shipping during introductory period for all Nimitra / Nikola purchases in December 2021. I hope this will be a fine Christmas present to audiophiles worldwide and happy listening. 🙂
