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

December 1, 2021 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. 🙂

Introducing Classic series of Nimitra and Nikola, the most affordable highend audio products

October 1, 2020 in News

After successful launch of Nimitra and Nikola Signature lineup, I gained a lot of experience and knowledge about building affordable products with better price performance ratio. After a lot of design and listening tests, Classic series of Nimitra and Nikola is finally ready.

The original Nimitra and Nikola have some limitations on pricing and they reached maturity in Signature series later. Classic series has improvements and corrections on original design for 2 years optimizing to get the most from Signature series.

Nimitra Classic - computer audio server

Nimitra Classic provides full support of Roon Core and Roon Ready with many other features such as DLNA/uPNP, OpenHome (Linn/Lumin), HQPlayer NAA, Airplay, and Squeezebox ready to be used with same optimizations as Signature version with only hardware changes as below.

-Same software features and optimizations as Signature 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

Since audiophile network switch is becoming standards in 2020, WiFi module will not be installed by default for better sound quality. You can choose to install WiFi module if you want to. I can still setup JPLAY and others as optional requests also.

Nikola Classic - linear power supply

Nikola Classic shares the same circuit design as original Nikola. It has some parts changed and adjusted to deliver better price performance ratio with high synergy to perform well in any system musically with some changes as below.

-Same circuitry design as original Nikola
-Regulator tuned for high synergy musical performance
-Compact 1.5mm Aluminum chassis for small space
-Audiophile grade capacitors used in some flagship products
-16 AWG teflon insulated copper internal wiring

I managed to find better cost effective parts with some design changes to bring the better performing products at more affordable price. Nikola Classic will be an ideal linear power supply solution for EtherStream and many other products with linear power supply too.

The price of Nimitra Classic is $995 USD and price of Nikola Classic is $395 USD. All Nimitra and Nikola products will have free shipping during introductory period until 31st October 2020 with 30-day money back guaranteed.

You can also purchase Nimitra and Nikola Classic series with EtherStream with free shipping and 2 outputs termination at $1785 USD. This combination is even more affordable than Nimitra Signature server and I hope this will help making highend audio more affordable.

Introducing NikolaS (Signature Upgrade) as premium upgrade version at $695 USD

October 30, 2018 in News

Hello everyone. After NimitraS being reviewed in StereoNET UK, Marc is also reviewing NimitraS with new linear power supply for StereoNET Australia review right now. It’s called NikolaS for Signature upgrade to match with NimitraS I released earlier.

As I built custom version of Nimitra, I also built custom version of Nikola too since its release. Sometimes we tried new designs with improved components or even new circuit design for clients. Sometimes I also built over $1,000 version of Nikola too.

But making an official product is different, you need to make sure it’s mature enough to stay like that for everyone with good reference, good reliability and selected parts won’t be changed after it hits production line.

Based on feedback I received with Nikola and its custom version, I can finalize the design plan for NikolaS as official product and release now. It’ll be an ideal match for NimitraS with firmware 3.0 update producing most analogue sound server and it can greatly improve sound quality of DAC and other servers too.

After research and development for price / performance ratio, the final price for upgrade to NikolaS is $695 USD with the following features.

NikolaS (Signature Upgrade) Features:

-Capacitors are upgraded with improved matching set providing fuller dynamics and richer sound
-IEC inlet is upgraded with Furutech FI-03 Gold model improving details and resolution
-Internal wiring is upgraded with 14 AWG high purity pure copper tuned for analogue sound (Made in USA)

Nikola customers can send unit back to apply NikolaS upgrade at $200 more meaning there’s no upgrade fee to upgrade from Nikola to NikolaS. Fidelizer will provide free shipping during introductory period for all Nikola purchases in November 2018.

You can read more about Nikola Linear Power Supply product and order with optimal voltage your audio device according to our recommendation. We also changed USB option to be USB Host meaning you can use any USB cable to connect with Nikola 5V version. 🙂

NimitraS Computer Audio Server review on StereoNET UK by Jay Garrett

September 8, 2018 in Review

Finally, the first NimitraS Computer Audio Server review is published. It was reviewed together with Nikola Linear Power Supply for completed NimitraS review. I’d like to express my gratitude to our UK distributor Elite Audio and Mr. Jay Garrett for this review

In this review, NimitraS was tested with a few DACs including Aqua La Voce DAC and Chord Qutest. I’ll have an appointment with Chord distributor about testing Nikola 5V version for Chord Qutest this Monday too. It seems he’s really pleased with NimitraS as you can see below.

Starting things off with a live version of ‘Big Love’ by Fleetwood Mac the instant realisation that there was greater detail and focus from the track when using the NimitraS when compared to my laptop plugged into the same DAC was nothing short of incredible.

Turning to a test track favourite and Nick Cave’s ‘Red Right Hand’ and again, the soundstage opened up more with the NimitraS. The performance through the Fidelizer server was just more visceral than through my laptop. Same track, same DAC, same NAS drive. But, apparently, it’s all just zeros and ones.

I have been impressed. I do love my PCs, and custom ones tend to trigger a reaction in me that is probably illegal in some parts of the world. That said, there is no mistaking the improved audio quality through this little music server.

On the date this review published, I received a message about sending NimitraS to StereoNET Australia for reviewing too. This will be my first time for regional product reviewing and I’m excited to see how it’ll turn out in Australia.

If you’re from United Kingdom and want to try NimitraS server, feel free to contact Elite Audio for auditioning and purchasing NimitraS Computer Audio Server with excellent services. 🙂

Nimitra Computer Audio Server and Nikola Linear Power Supply receives inearspace’s Pride of Place Award

May 28, 2018 in Review

This review was actually published in last month for both Nimitra Computer Audio Server and Nikola Linear Power Supply. However, I was overloaded with orders to finish before attending the show so I couldn’t publish it right away. I’ll start publishing feedback received too.

This is probably the first serious review for Nimitra and Nikola in headphone systems so I hope this will be a good reference for headphone users to consider using Nimitra and Nikola with headphone setup.

The Nimitra is none of the things that the iMac is. It is not loud nor brash and seems to have a controlled fluidity to it. Keetakawee made a big statement when he went along and said that this was an a server for analogue lovers but I think he may just be onto something here. Obviously the rest of my system is helping achieve such an analogue sound, the R-2R arrangement in my d1-seven certainly helps, as does that lusciously tuned Audeze LCD-MX4 but there is an apparent glare with the same system running off the mac, and noticeable artifacts all through the sound and they just aren’t there with the Nimitra, instead the background is dead quiet. The best part is this is all the quiet before the storm, it starts controlled, quiet and smooth but then you realize the intense dynamism that this is capable of, something that really comes out with Jack White’s new LP “Boarding House Reach”. While the Linux based BMC PureMedia wasn’t as distorted or lively as the iMac, it didn’t ever provide that crunch, that power and that is where the Fidelizer really moves things on a gear. It makes the BMC sound sterile and boring yet it is as refined, it has better emotion and realism, aided by a firmer (but no more present bass) and more agile and snappy treble.

I’m happy to hear Mr. Sonny Trigg loves Nimitra enough to give Nimitra the first “Pride of Place” award in server category. You can read full article about Price of Place Award and see other cool products and don’t forget to check his Nimitra and Nikola review too. 🙂
