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

 

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.

Fidelizer Nimitra Firmware 6.0 Updater is released with overhaul optimizations based on Erawan flagship streamer

 

Nimitra Firmware 6.0 Updater

 

After releasing firmware 5.0 in 2022, we’ve been improving Nimitra internally and apply newer changes and improvements over the years until it reaches maturity stage to make it official. Today is the day we can announce official firmware 6.0 update.

Version 6.0 will cover major improvements based on Erawan flagship streamer that can be applied into Nimitra product. Firmware 5.0 was biggest improvement but 6.0 is now bigger with overhaul optimizations and improvements as below.

 

Windows Server 2025 Sound Quality Optimizations

 

After being impressed with sound quality from Windows Server 2022 for the first time enough to put onto Nimitra firmware 5.0, Windows Server 2025 made further improvements and changes are tailored for Nimitra to bring streaming closer to real sound.

Erawan was launched in the same month as Windows Server 2025 being released officially so we have been working closely with 24H2 codebase since the first beta. We’ve been optimizing Erawan until last week before making local launch in November 2025.

It’s quite fortunate for Nimitra that changes from Windows Server 2025 can blend smoothly with NimitraOS optimizations making Nimitra Classic and Nimitra2 sounding a lot closer to Erawan at much more affordable price point.

 

Universal Core Isolation Policy and Playback Optimizations

 

Nimitra Firmware 6.0 Updater - Main

 

When firmware 5.0 was released, it was mainly for Roon optimizations at first and we put JRiver improvements during last minute before official launch. After Roon failing to meet our expectations, we started working on universal optimizations.

We work closely with developers who are our partners like Audirvana to bring the most satisfying experience to our clients with optimizations on Nimitra. The change of direction to universal approach will optimize all audio applications.

 

Core Isolation Policy:

Single core (Recommended for low latency audio playback)
Dual cores (Recommended for high buffering audio playback)
No isolation (Disabled)

Playback Optimizations:

Standard optimizations (Default recommendation)
Enhanced optimizations (Improve playback performance)
Max optimizations (Full real-time process optimizations)
Safe optimizations (Improve Roon’s reliability)
Extra-safe optimizations (Fail-safe optimizations)
No optimizations (Disabled)

 

Default configuration will use dual core isolation and standard optimizations now to maintain good synergy and reliability with most devices. Customers can also request for optimal configuration for their system to get the best sound quality possible.

 

Improved reliability with Roon/JRiver Optimizations

 

FidelizerRemote

 

After releasing firmware 5.0, we noticed a few unusual issues with Roon and JRiver software used in Nimitra and added workaround to resolve the following cases as below.

  1. Roon keeps eating up space after applying a few updates so all temporary files will be cleaned up before loading Roon on startup
  2. JRiver has occasional issues with USB audio not being responsive due to having pause on audio playback so it will stop after a long pause

Firmware 6.0 will address these issues and keep Nimitra stable with unusual cases but we do care enough to bring the best music experience.

 

Improved internal system and application optimizations

 

There’s a lot of internal system and application optimizations in firmware 6.0 to further improve audio performance in this release. Even Airplay now will bring outstanding audio performance and some application files are updated to more recent version.

More unused features in audio platform and operating system are disabled to further reduce interference in system and bring inner fidelity of streaming to the next level along with improved internal system optimizations.

 

Improved quality of life improvements based on ErawanOS

 

After releasing Erawan, there’re a few changes being requested by clients and store vendors to bring to Nimitra too. For example, changing track with JPLAY in Erawan will have smooth fade out before playing a new track. This is implemented in firmware 6.0 too.

Some other unique optimizations from Erawan are also implemented on Nimitra such as disabling core parking and USB’s power saving features so Nimitra will improved sound quality and user experience being more similar to Erawan for what Nimitra can achieve.

If you’re using Nimitra Classic, I’d like to inform that Nimitra Classic will be discontinued in future after successful launch of CoreStream streamer. So, you can upgrade your Nimitra Classic to Nimitra2 at $1,500 USD only.

Nimitra runs on specially tuned NimitraOS platform with special version of Fidelizer. All these optimizations are specially tuned for Nimitra’s hardware and software configuration, separated from Fidelizer software optimizations.

Nimitra Classic / Nimitra / NimitraS / Nimitra2 customers can send request for firmware update and I’ll update Nimitra firmware through remote or request download link for applying update manually.
