Introducing Fidelizer Nimitra3 streamer, Nikola3 linear power supply, and CoreStreamOS for CoreStream streamer

 in News

 

Nimitra3 - Front

 

After the completion of Erawan flagship streamer and Lira network station, I have been spending a great amount of time and effort into refining and improve NimitraOS based on Erawan which is my masterpiece together with Lira for over a year now.

The reason I have been working so hard was because I have a few clients who ordered Nimitra custom highend version and I have been working with them locally to reach the same height as Erawan. By the time I finished refining custom highend Nimitra version, it’s almost my 40th birthday.

With on going changes in market demand and Ai disruption that affected production cost of computer worldwide, I decided to launch Nimitra3 streamer and Nikola3 linear power supply upgrade with major changes in product lineup in this month that I’ll be forty years old.

 

Nimitra3 - Rear

 

Let’s start with Nimitra3 streamer first. After finishing Nimitra custom highend upgrade design, I implemented new changes into Nimitra3 with some hardware changes such as 8GB RAM to handle Audirvana / Roon smoothly. SSD has high precision clock upgrade too.

I also designed a new chassis for Nimitra3. It’s minor change but they are changes based on Erawan design to fit into Nimitra3. I printed back panel to show information better and change footer with gold finishing to match with Lira network station.

There’re a lot of internal changes and I don’t want to bloat this news with technical jargons so I’ll wrap up for Nimitra3 upgrade as below.

 

-NimitraOS is upgraded to Windows 11 24H2 based on ErawanOS design
-BIOS is optimized and tuned with recent optimizations for optimal performance and sound quality
-RAM is upgraded to 8GB with customized and tested model for approved sonic performance
-SSD is upgraded with high precision clock similar to how Erawan has SSD with upgraded clock

 

Long story short, Nimitra3 is reborn with Erawan as reference. Getting Nimitra3 + Lira together will save half of investment from Erawan for the most cost effective upgrade experience. Some people upgraded to Nimitra3 before official and they all are loving it.

 

Nikola3

 

Now let’s move on to the next upgrade Nikola3 linear power supply. Nikola3 is based on Lira network station design without network part so they share the same internal parts and circuit design including gold plated XLR termination outputs.

Nikola3 will come 2 outputs and DC cables just like Aura medical grade power supply with the following upgrades below.

 

-Change output connector to gold plated XLR with very high voltage rating (same termination as HDPlex)
-Upgrade DC output cable with high quality pure copper wiring
-Upgrade diodes with Schottky design with years of listening tests with different models
-Upgrade internal wiring with high quality solid core pure copper wiring
-Upgrade output transformer with 100VA Toroidy audio grade transformer
-Upgrade stock fuse with improved dynamics and musicality

 

Lira network station is a perfect companion with Nimitra3 that can provide both network and power infrastructure but you can consider Nikola3 if you have preferred audiophile network switch. It’s also possible to upgrade from Nikola3 (12V) to Lira in future too.

 

CoreStream - Top

 

And here’s the most exciting news for CoreStream owners. CoreStreamOS is ready and this will enable all software features to make CoreStream working in the same way Nimitra and Erawan are operating. This will give a lot of depth into software optimizations.

CoreStream will come with premium streaming platform and receive unique optimizations such as runtime optimizations for Audirvana / Roon that will be introduced in future firmware updater release. I’m working on big platform upgrade with Audirvana now.

 

Anyway, there’s a big reason for CoreStream upgrade. As you may know already that the price of computer components have increased a lot due to Ai demand. The hardware cost of CoreStream got increased to the point that I should have launched CoreStream at $1299 USD.

But I feel bad to just increase the price because the market situation so I decided to turn CoreStream into full fledged streamer with CoreStreamOS and replace Nimitra Classic with CoreStream. Nikola Classic will also be discontinued (You can still order the last batch in this month).

The reason why I have to discontinue Nikola Classic is due to increased cost of parts and I can no longer stock multiple transformers with different voltages since I started importing transformers from Toroidy. Aura can deliver good results at very affordable price too.

I believe Nimitra3 and Nikola3 will deliver endgame streaming quality in your system for years to come after being reborn with Erawan and Lira as reference products. Here are the current price list of current streaming products launched today.

 

Nimitra3 streamer: $2,900 USD
Nikola3 linear power supply: $1,299 USD
CoreStream streamer: $999 USD

 

With increased hardware cost on increased RAM capacity and storage quality, I hope to deliver fairest approach to customers who purchased Nimitra before with flexible upgrade price based on market’s situation. I’ll list Nimitra3 upgrade at $100 USD first and pay the rest when done.

About $300 USD increased on CoreStream, I’d like to clarify that there’s $100 USD worth of software license and over $100 USD for parts cost increased. I didn’t take profit for myself and cover the cost for retailers too. You can return the product within 30 days so no risk at all.

We are moving forward with a lot of changes in this year and I believe we are moving towards the right direction despite the challenges in current market situation. I’m preparing future product line up for years to come that will set new standards for audiophiles.

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. 🙂

Nikola2 Linear Power Supply review on Audio Bacon by Jay Luong

 in Review

 

Nikola2 - Linear Power Supply

 

The first review of Nikola2 Linear Power Supply by Mr. Jay Luong was published in Audio Bacon for a long while. I’ve been very busy and kept forgetting to publish this review but it’s finally up now with very positive results.

I’m glad to see that Mr. Jay appreciates how Nikola2 can bring real sound performance that he can hear from real life instruments. It’s Nikola2 design philosophy to deliver world class tone and timbre as mentioned in his review.

Also, I’m very honored to know that he regards Nikola2 to be the power supply equivalent of my reference USB cable and decided to keep Nikola2 as he mentioned in his review. That’s the best moment for every manufacturer.

Positive Feedback

As far as power supplies still being sold, the Fidelizer Nikola2 power supply has the best tonality and timbre in the entire lineup. It has a fantastic amount of tonal variance, soul, and essence. It’s incredibly tactile, balanced in fullness, and articulates with just enough precision. Because of that, you’re able to hear subtle timbral and cues and resonances that are usually masked by other power supplies. This is consonant with what I hear in real life.

Thank you again for this wonderful review of Nikola2 product. You can read his full review and see how Nikola2 performs compared to other linear power supplies to understand how linear power supply can improve sound quality better.

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. 🙂

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

 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.
