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

 in News

 

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.

 

Changelog

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.

Introducing CoreStream, Fidelizer’s most affordable streamer that meets highend audio standards

 in News

 

CoreStream - Close up

 

When I was exhibiting products in BAV audio show during 6-8 June 2025, I received a request from my friend’s store about building an affordable streamer as a Roon core. Although there’s also Nimitra Classic but most people prefer Nimitra2 as true contender.

After giving some thoughts and consulted with a few hifi specialists, we finalized the design for “CoreStream” streamer that can handle 300,000 songs in Roon library with can handle MUSE DSP efficiently. CoreStream also come with other streaming solutions similar to Nimitra too.

We built CoreStream with vision in mind to create the powerful Roon core while maintaining low power requirements and noise. We chose Intel N100 processor because it draws only 6W but can scale with high performance to handle Roon/Audirvana/HQPlayer tasks better.

 

CoreStream - BIOS

 

Despite being the most affordable streamer we can offer, we don’t let go of our standards to develop quality products. We still work closely to manufacturers and develop a custom BIOS, designed for audiophiles with intensive listening tests with flagship CD player as reference.

As a result, CoreStream streamer can deliver audio performance that can feel like listening to real music. We don’t build products to be just acceptable in audio system as background music. It must bring out emotion to feel the real sound from your system too.

Before launching CoreStream, we have a few audiophiles visiting our room and demonstrated CoreStream together with CD playback from flagship CD player in our system. Our clients are all satisfied saying it sounds very close to CD.

 

  • uPNP
  • Audirvana
  • JPLAY
  • HQPlayer
  • Airplay
  • Roon

 

The reason why CoreStream can sound close to CD was because we implemented foobar2000 setup assistant we launched to help Fidelizer users setting up a streamer and took steps further to optimize for optimal sound quality with CoreStream streamer.

With intensive listening tests and adjustments on custom BIOS and software configuration, CoreStream can become a reference point to demonstrate how audiophiles can feel the real sound with Fidelizer sound experience from CoreStream as a starting point.

CoreStream can stream music with Airplay / uPNP / Roon Core / Roon Ready / HQPlayer NAA / Plays with Audirvana right out of the box and users can request remote support to provide assistance with software configuration and updates.

 

CoreStream - JPLAY

 

With FidelizerOS that shares a lot of similarity with NimitraOS developed in Nimitra streamer, CoreStream can run on lightweight operating system with special version of Fidelizer designed for dedicated streamer product with the following optimizations.

 

CORE #1: HQPlayer NAA daemon / RAATServer
CORE #2: foobar2000
CORE #3: foobar2000
CORE #4: non-audio processes

 

With this configuration, foobar2000 won’t interfere audio thread on Core#1 and won’t share thread with non-audio threads in Core#4. HQPlayer NAA daemon and RAATServer will run as endpoint on Core#1. These audio processes will run at high priority to ensure optimal performance.

As for hardware specifications, CoreStream shares a lot of design from Erawan flagship streamer as below:

CPU: Intel N100 processor (With custom BIOS for optimal audio performance)
Memory: 8GB DDR4 3200MHz dual channel
Storage: Enterprise grade SSD
USB: 2 x USB Audio (blue) / 4 x USB Storage/receiver (black) / 1 x USB Type-C
Ethernet: 2 x 1Gbps
Display: 1 x HDMI / 1 x DisplayPort
Power supply: 100 – 250 VAC
OS: FidelizerOS (Custom Windows 11 Pro 24H2)
Supported streaming platform: Airplay / uPNP / Roon Core / Roon Ready / HQPlayer NAA / Plays with Audirvana
Product features: Remote support / Custom feature request if applicable
Dimension: 140mm x 115mm x 50mm (W x D x H)
Weight: 1.5kg

 

CoreStream - Top

 

CoreStream can deliver streaming audio experience in the way we envision to deliver quality streamer together with Aura medical grade power supply and HyperLink network switch at around $1,000 USD budget which is finally possible now.

The product price will be $699 USD with 30-day money back guaranteed and free shipping until 31st August 2025. You can read more about CoreStream streamer product in details before ordering and happy listening.

Introducing Erawan, the flagship streamer that brings music of the eras to life

 in News

 

Erawan - Cover

 

After 8 years of development, Fidelizer’s flagship streamer product called “Erawan” is now ready to be shipped to overseas. It took 8 years because we set the main goal of Erawan to deliver streaming quality that we won’t miss flagship CD transport.

We could have released Erawan sooner and take advantage from Nimitra’s enormous success before COVID-19 but we want to release something that won’t make you miss CD, something that even vinyl lovers will be interested to hear. This is our mission, not business.

 

To make sure Erawan will really deliver quality we strive for, we conducted internal research and development with Esoteric Grandioso K1X which was one of the best CD players in market today. After reaching on-par performance to reference CD in our systems, we brought Erawan to test outside.

We gained a lot of new experience testing products in different systems. Hearing Erawan against Esoteric Grandioso P1X SE + N-01XD SE in bigger room with bigger reference system taught us a lot more about limitations of digital audio. It brought us joy and suffering at the same time to overcome.

 

Erawan - Reference

 

We also tested Erawan with a few $50-100k turntable setup too and our goal expanded to how we can deliver full scale analogue sound experience like that with streaming as medium. We kept researching relentlessly until we success in developing flagship streamer as we envisioned.

With completely new design from ground up for both hardware and software, Erawan can stream old and new music faithfully and bring whole new experience that you can even compare to Nimitra2 and hear the difference in recorded video clip as below.

 

 

  • uPNP
  • Audirvana
  • JPLAY
  • HQPlayer
  • Airplay
  • Linn
  • Lumin
  • LMS
  • Roon

 

The biggest challenge in developing flagship streamer is reproducing full scale analogue sound performance in highend audio systems. Many audiophiles often struggle to play old favorite songs in streaming platform because it couldn’t bring the life of that era back.

Erawan will stream your favorite old and new songs faithfully and reproduce every part of music as if you travel back in time and listen to music in that era again. We developed a cutting edge technology to bring the best of old and new technology as below.

 

ErawanOS based on Windows 11 Enterprise LTSC 2024

ErawanOS’ development started since 2019 when we finally found a promising version of Windows 10 that sounds decent after the original NimitraOS version. We have been updating until finalized ErawanOS with official Windows 11 Enterprise LTSC 2024 release.

Since original NimitraOS, we are the first to develop streamer with process core isolation feature into audiophile market since 2016. In ErawanOS, we are the first to develop streamer with core isolation feature at hardware level into market as below.

 

CORE #1: Core Audio / Clock and Timer drivers
CORE #2: Network devices
CORE #3: USB and audio devices
CORE #4: Storage and graphics devices

 

With important hardware devices isolated to different cores at higher priority (except graphics devices), Erawan can finally stream music at higher fidelity with improved performance on both dynamics and transparency.

ErawanOS is also developed from ground up differently from NimitraOS to decrease hardware latency and jitter. There’s a lot of new and unique optimizations, combined with Windows Server 2025 optimizations and internal improvements to deliver full sound similar to real vinyl.

 

 

Flagship quality linear power supply design

Erawan flagship streamer has built-in linear power supply with completely new design for flagship highend audio quality. With completely new circuit design using voltage reference circuit. We can finally reproduce transport quality similar to flagship CD transport level.

Besides new power supply circuit design, we also use highend grade components as below:

-100VA AUDIO GRADE toroidal transformer from Toroidy
-Silicon-carbide diodes from Cree
-Polymer hybrid output capacitor
-Solid core pure copper internal wiring

With new design of flagship linear power supply, Erawan can faithfully reproduce music with fuller dynamics and yet it can reveal more micro detail and decay at the same time. This power supply helps Erawan controlling low frequency to reproduce real analogue performance.

 

Erawan - Features

 

Next generation of hardware design that can handle high performance applications

In early designs, we used to develop Erawan prototype based on Intel powerful i7 processors to handle high complexity tasks but powerful processor won’t allow us to maintain flagship CD transport level of transparency even with best power supply.

So, we develop a new solution based on more recent technologies and found new sweet spot that can maintain flagship CD transport level of transparency while providing more dynamics with scalable processor design with ultra low latency RAM.

As a result, Erawan can maintain the same principle of being low powered design similar to Nimitra. However, this next generation design is capable of handling powerful tasks like DSD256 upsampling as Roon core and Audirvana for better performance.

We also upgraded clock in motherboard’s chipset and storage to further reduce jitter at more fundamental levels with new technology of components. Now Erawan can have both transparency of low powered and full scale sound of powerful processor, best of both worlds.

 

Separated USB/Ethernet ports for optimal audio performance

Erawan now comes with two separated ethernet ports, 1Gbps and 100Mbps for high bandwidth and low noise applications. Some highend ethernet cables have fast ethernet design for low noise and Erawan is fully compatible with fast ethernet design on 100Mbps port.

USB ports also have high-end grade modification to make onboard USB streaming full and uncompressed dynamics in large room. But if you want to install external USB card, low-profile PCI slot will fit in Erawan based on audiophile cards we tested before.

 

Just like Nimitra, Erawan can work with the following applications from different platforms as below:

 

Windows: Kazoo, Kinsky
Mac: Kazoo, Kinsky
iOS: JPLAY, Kazoo, Kinsky, mconnect Player, Lumin
Android: Kazoo, Kinsky, mconnect Player, Lumin

 

Erawan supports many features such as DLNA/uPNP (Audirvana/JPLAY/mConnect Player), OpenHome (Linn/Lumin), Airplay, Audirvana, HQPlayer, JPLAY, Roon and SqueezeBox ready to be used as plug and play solution.

 

As for hardware specifications, Erawan has gone through a lot of design changes from improved low powered server design to powerful server with flagship processor quality. At the end of the day, Erawan was finalized with these specfications as below:

CPU: Intel Elkhart Lake Pentium N6415 Quad Core processor (Up to 3.0GHz)
Memory: 16GB DDR4 3200MHz dual channel
Storage: Audiophile Grade SSD SLC mode (Optional: 1-4TB SSD with highend grade SATA cable on request)
USB: 2 x USB Audio / 2 x USB Storage / 2 x USB 2.0 side port
Ethernet: 1 x Intel I211-AT 1Gbps / 1 x Intel I211-AT 100Mbps
Display: 1 x HDMI / 1 x DisplayPort
Expansion Slot: 1 x Low-profile PCI Express X1
Power supply: 100 – 250 VAC
Grounding: Chassis ground support with ground conditioning products
OS: ErawanOS (Custom Windows 11 Enterprise LTSC 2024)
Supported streaming platform: Airplay / uPNP / OpenHome / LMS / Roon Ready / HQPlayer NAA (Audirvana, HQPlayer and Roon on request)
Product features: automate library server management / TeamViewer remote support / Web remote
Dimension: 365mm x 307mm x 120mm (W x D x H)
Weight: 7kg

 

This hardware design is finalized and future proof as it can handle Roon and Audirvana with DSD256 upsampling. Even Nimitra that was design 8 years ago which can still keep up with Roon today with firmware updates.

We already sold 5 units of Erawan before global launch so we have a few cases of users with different platforms to make sure Erawan will deliver smooth transition without interruption. As Esoteric Grandioso K1X SE owner, we can proudly say Erawan made these people happy no less than CD/vinyl format.

 

Erawan - System

 

The product price will be $8,900 USD with 30-day money back guaranteed and free shipping until 31st May 2025. You can read more about Erawan flagship streamer product in details before ordering and happy listening.

Roon core version selection is available for Fidelizer Nimitra Computer Audio Server

 in News

Nimitra2

 

After Roon 1.8 update, Fidelizer starts developing unique Roon optimization for Fidelizer Nimitra as Roon core and things have been going well so far. There’s some sound signature changes during Roon 2.0 updates but still sound acceptable for serious listening.

However, Roon 2.0 starts adopting CarPlay support in recent updates and some audiophiles feel they can’t enjoy music from Roon as they used based on feedback received from customers and friends asking me if I notice changes in sound with recent Roon update.

I investigated and tested different 2.0 builds and found that Roon 2.0 build 1182 sounds more preferable as the last build before CarPlay support. I shared my findings in Roon’s community hoping devs can test things out but my feedback wasn’t well received.

 

It looks like Roon 2.0 will focus on adopting more features to provide more accessibility such as Roon ARC and CarPlay and those changes may cause sound signature changes in some systems over time. For audiophiles using Roon solely for serious stereo system, this isn’t good news.

So, I went back to Roon 1.8 Legacy and start fresh since Roon’s database can’t be downgraded from 2.0 to 1.8 release. To my findings, it sounds decent, get the jobs done and I won’t have to worry about new updates causing change in sound signature like Roon 2.0.

 

After testing Roon 1.8 Legacy today, I decided to add Roon core version in Fidelizer Nimitra Computer Audio Server with Roon 1.8 Legacy as default option. You can also upgrade to 2.0 at any time from backup and Roon 2.0 that can’t be downgraded.

If you’re using Fidelizer Nimitra as Roon core running version 2.0 and want to setup Roon 1.8 Legacy version, I can backup your Roon 2.0 repository and start new Roon core 1.8 legacy for you to try and see if you want to keep using Roon 1.8 Legacy version.

I’d like to assure you that Fidelizer Nimitra server is still fully compatible with Roon 2.0. This option is a matter of personal and subjective experience about sound changes in different version updates. As old saying goes “If it ain’t broke, don’t fix it”.

Fidelizer Nimitra Firmware 5.0 Updater is released with Windows Server 2022 Sound Quality and Roon/JRiver Optimizations

 in News

 

Nimitra Firmware 5.0 Updater

 

After releasing Nimitra2 with improved hardware modification, I’ve been optimizing Nimitra2 to improve sound quality with new standards. With new VRDS ATLAS transport from Esoteric K1X Grandioso, I finally brought Nimitra2 to masterpiece level with firmware 5.0 update.

Version 5.0 will cover changes in various areas to improve sound quality and also reliability with better user experience. This is probably the biggest update since launching Nimitra 6 years ago. Here’s summarize about major updates in version 5.0 update.

 

Added Windows Server 2022 Sound Quality Optimizations

 

Many people said Windows Server sounds a lot better but personally I prefer sound signature from some Windows 10 builds more so I didn’t look into Server builds as much until this year. When I tried Windows Server 2022 this year, I was blown away by Windows Server 2022’s performance.

If we were to compare how Windows sounds as stock environment, Windows Server 2022 is no doubt the best sounding Windows. But I don’t think sound quality from Windows Server 2019 to 2022 will be improved with any major changes on system files so I tried to crack the secrets.

This year I spent a long long time researching on the difference between my favorite Windows 10 builds and Windows Server 2022. I compared all parts of registry and system configuration between these two and finally managed to crack the secret sauce of Windows Server sound.

The main reason why Windows Server sounds better is default configuration for Server version have some parts that favors sound quality better. I traced the changes and applied the applicable differences I found into NimitraOS and viola! NimitraOS sounded very similar to Windows Server 2022.

But it doesn’t end at just that. Some changes from Windows Server configuration are not for better sound quality. There’s difference ups and downs so I tried to implement bits by bits and adjust configuration for optimal sound quality.

After this long process of trial and error with listening test, I finally managed to integrated Windows Server 2022 configuration into NimitraOS with optimal sonic performance. At this point NimitraOS already has better sound quality than Windows Server 2022.

 

Added Roon Sound Quality Optimizations

 

Nimitra Firmware 5.0 Updater - Main

 

Since Roon 1.8 update, I started using Roon more to discover new music with Roon Radio feature. It also sounds better than previous versions so I started taking Roon seriously and tried to find a way to make Roon delivering better sonic performance highend audio system.

After a long research along with Windows Server 2022 sound quality optimizations, I managed to to find a method to deliver highend audio performance with Roon. Roon has 3 main components which are:

RAAT: Managing audio streaming between devices
Core: Managing core features in Roon core
Appliance: Managing essential tasks like database and DSP

Understanding how each component works, I can optimize Roon in Nimitra with two main principles to improve sound quality:

Core Isolation: Nimitra has 4 cores so I can isolate Roon components into different cores. I still need Appliance to have all cores or Roon will be too slow.
Priority Optimizations: By increasing RAAT’s priority which involves handling audio transport directly so Roon can have better audio performance.

After testing out a few combinations, I managed to sort out Roon Optimizations with the following options below:

 

Roon Core Isolation Policy:

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

Roon Playback Optimizations:

Standard optimizations (For all media sources)
Local optimizations (For internal/external storage)
Streaming optimizations (For NAS/streaming services)
MQA optimizations (For MQA Core Decoder)
No optimizations (Disabled)

 

Default configuration will use single core isolation and standard optimizations. Customers can also inform about their system for applying firmware update with optimal configuration for their system to get the best sound quality possible.

 

Added JRiver Sound Quality Optimizations

 

FidelizerRemote

 

After finishing Roon optimizations, I started working on my favorite platform JRiver to get better sound quality too. With custom tuning for lower latency, JRiver can deliver audio performance closer to live performance with zero latency jitter.

 

JRiver Latency Optimizations:

Ultra low latency (100ms)
Low Latency (200ms)
Standard (1000ms)
Reliable (2000ms)
Relaxed (4000ms)
Safe (6000ms)
No latency change

 

Default configuration will use low latency at 200ms which is stable enough for most cases. Technically it could as low as 50ms but such scenario can only be possible with non-highres format in highly controlled environment.

I also added “Enable pure playback (disable plugins in audio chain)” to be used by default since default configuration can use this feature. This will disable audio related plugins from audio chain completely for true pure playback.

JRiver platform also has improved FidelizerRemote web app supporting light/dark theme configuration and have better library browsing and playback control based on Roon UX too. You can access FidelizerRemote through http://nimitra_sn[written serial in sticker/box].local

 

Revised Sound Signature Profile optimizations

 

I used to offer two sound signature profiles but it’s no longer necessary with new finalized configuration based on Windows Server 2022 that can deliver the best of both worlds. In this firmware 5.0 update, Sound Signature Profile is now changed to options based on Fidelizer software as below.

 

Sound Signature Profile:

Natural harmonics with linear sound
Natural harmonics with rich details
Sharp image with linear sound
Sharp image with rich details

 

Default configuration will use “Natural harmonics with linear sound” option based on Esoteric CD transport as reference. They’re tuned slightly different from Fidelizer for optimal sonic performance with NimitraOS platform and hardware.

 

Improved NimitraOS core sound quality optimizations and quality of life improvements

 

Besides Windows Server 2022 / Roon / JRiver optimizations, NimitraOS also has internal optimization improvement too. I added .NET Framework performance optimizations to improve performance and sound quality with Roon. Some internal configuration are optimized for better sound quality and reliability.

I also updated OpenHome/NAA libraries with improved configuration too. If you use OpenHome feture with Linn/Kazoo/Lumin/Sound Stream app, please inform support during update.

 

Changelog

-Added .NET Framework performance optimizations to improve performance with Roon
-Added JRiver’s latency optimizations to improve sound quality on JRiver’s based platform (FidelizerRemote / uPNP / OpenHome / LMS)
-Added JRiver’s pure playback mode disabling plugins in audio chain completely
-Added Roon optimizations features with core isolation and priority optimizations options
-Added Windows Server 2022 sound quality optimization into NimitraOS
-Improved JRiver audio output configuration for better sound quality
-Improved internal optimizations for better performance and reliability
