Nimitra Firmware 7.0 was scheduled to be launched with Nimitra3 / Nikola3 in August 2026 but there’s a lot of new optimizations to work on such as PerfectDynamics optimizations on Audirvana and Roon and Fidelizer 9 too.

Now that everything is finalized for completion, Nimitra firmware 7.0 is now ready. This upgrade is quite special due to Fidelizer 9’s engine with new core optimizations so both of new engine and firmware update will come together.

 

Fidelizer 9’s core optimization engine

 

With reworked optimizations of Fidelizer 9 release, Fidelizer streamers that will receive Fidelizer 9.0 core optimization engine together with firmware 7.0 update. This new engine will bring new life to Fidelizer streamers that could be considered as major upgrade.

This core optimization will greatly improve musicality and make Fidelizer streamers sounding more organic and lifelike in a way that can only be achieved through real analogue recording. But now streaming can feel that similar experience thanks to this new engine.

 

Tidal / Qobuz / Spotify Connect with exclusive playback support

 

 

As some people requested about Connect feature for Fidelizer streamers to work with native application directly, I developed solutions for Tidal / Qobuz / Spotify to work with connect feature also. At first they aren’t mentioned because most people stopped using it later.

But since there are a lot of customers who prefer to keep native user experience with Connect feature, I’d like to make this clear that Fidelizer streamers can implement Connect feature with exclusive playback support including Spotify also.

If you want to implement connect feature, please contact me and we can schedule remote session to implement this function on your streamer. Sound quality on Connect feature will perform great with Fidelizer 9’s core optimizations in dedicated environment.

 

Expanding support Erawan and CoreStream streamer

 

Since Nimitra streamer project has been scaling into Erawan and CoreStream, I planned about releasing Erawan 2.0 firmware after Nimitra 7.0 firmware later. But change on CoreStreamOS made me realized a single firmware for all streamers is better approach.

So, Nimitra firmware 7.0 will support Erawan flagship streamer and CoreStream streamer also. New changes and improvements will apply on all Fidelizer streamers in a way that is suitable for target streamer.

 

PerfectDynamics optimizations for Audirvana and Roon

 

Ever since Fidelizer has partnered with Audirvana, I’ve been working closely with Audirvana to provide the best experience to clients who use Fidelizer streamers with Audirvana software and assisted Audirvana on different occasions.

After Audirvana migrated platform to .NET 10 runtime, I have been working on making the most of .NET 10 runtime optimizations for and develop proprietary optimization technology for Fidelizer streamers with Audirvana.

After the completion of this new technology, Audirvana has become Fidelizer’s new reference platform that can provide PerfectDynamics using Kernel Streaming Extreme without harshness or fatigue and capture real sound performance perfectly.

Roon also migrated to .NET 10 runtime too so I expanded PerfectDynamics tuning to latest version of Roon platform too. Although current Roon doesn’t meet Fidelizer standards anymore, this update helped some clients moving from Roon 1.8 to current Roon now.

 

Improved uPNP streaming sound experience

 

 

As Audirvana and Roon getting big improvement with PerfectDynamics sound optimizations based on new proprietary software tuning technology exclusively for Fidelizer streamers, uPNP streaming is also improved a lot too with deeper level tuning.

Pure playback optimization now disables more components reducing footprints further bringing quieter noise floor and core engine is further optimized to reduce interference in software to reduce non-audio workload.

Streaming latency is also enhanced with smooth transition for better playback experience. Stop / Pause playback will not stop music abruptly. Changing track can be adjusted between 0.5 / 1 / 2 / 4 second(s). Low latency options won’t have smooth track change.

 

Improved internal system and application optimizations

 

There’s a lot of internal system and application optimizations in firmware 7.0 to further improve audio performance in this release. Airplay now will have perfect a/v sync with Apple products like AppleTV and some application files are updated to more recent version.

Internal system optimizations are improved with improved reliability bring further stability across different playback platforms. With firmware 7.0, CoreStream / Nimitra / Erawan all can perform with the same reference real sound experience as best in its own class.

This firmware update is based on current CoreStreamOS / NimitraOS / NimitraOS running on Windows 11 24H2 and can be installed on older models of Nimitra units to enhance current features installed.

If you’re using older Nimitra models, you may consider upgrading your current Nimitra model with Nimitra3 Streamer Upgrade Plan to get the best music experience, especially with Audirvana and Roon.

Erawan / Nimitra / CoreStream customers can request for firmware update and I’ll update Nimitra firmware through remote support. Feel free to contact through email or support channel to schedule remote session.
