Regarding Roon issues with some hardware devices including Nimitra in update 1.8 build 880

UPDATE: Roon 1.8 build 882 is released now and it’s working fine with Nimitra. Please contact me for updating Roon to latest version and happy listening.

 

Hi. Today Roon launched new update 1.8 build 880 and some Nimitra users has the following issues

  1. Database is corrupted (which it is not but build 880 can’t read database for some reason)
  2. There’s no audio device in Audio section at all

These issues are from changes in build 880 that doesn’t work properly with some hardware and it’s widespread issues through Windows/Mac/Linux platforms. You can check Roon Support section for more details about 1.8 build 880 update issues.

For current workaround I can rollback Roon core to version 1.8 build 831 which is stable with Nimitra. You can download Roon 1.8 build 831 from the following links below to control until they release an update that fixes these issues.

 

Roon 1.8 build 831: PC / Android / iOS (Not available outside App Store)

 

iOS devices can’t install older Roon version so only PC and Android can perform rollback for now. Please contact Fidelizer support for setting up Roon 1.8 build 831 rollback. You may consider using other apps like mConnect / Lumin / Kazoo to control Nimitra also.

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

 

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. 🙂
