Re-introducing NimitraOS, I think it’s time to address Nimitra’s platform and features properly

 in News

Last year I was so busy preparing and shipping a few Nimitra units including some special custom order ones. This year I have a bit of time to develop and research on various things and today I realize it’s time to properly re-address about Nimitra’s core competencies in software.

Back then the idea of introducing software features in Nimitra as OS sounds technically incorrect since OS is Windows 10 and doesn’t sound sincere. That’s what I thought and introduced as Nimitra Edition Platform with a bit too short description since I was too focused on sound quality alone.

While I was working on Nimitra updates recently, I realized I didn’t mention many useful features I developed at all. And thinking again most Linux-based OS are actually distros packed with different kernel and software. Some are actually dressed popular distros or tweaked ones.

So, it would sound appropriate address these features in platform as OS for user to understand Nimitra better and I’ll name it NimitraOS. At least this should make more sense than Windows 10 Nimitra Edition Platform. I updated NimitraOS in Nimitra product page as below.

 

NimitraOS: Fidelized Windows 10 Platform for audiophiles

 

Windows 10 comes with many features unrelated to audio solutions. Some may tweak OS to disable unused features and services. NimitraOS optimizes at roots by removing all non-audio features from installation itself, with dedicated optimizations to maximize audio performance.

 

Fidelized Windows 10 Pro debloating performance

 

This reduces RAM usage to only 1GB in fully operational mode with special version of Fidelizer as CAS platform using specialized optimizations that can ready your system in about 30 seconds from power on. NimitraOS is the most solid Windows platform optimized for audiophiles.

NimitraOS also come with assistant software maintaining products and services used in Nimitra such as maintaining library database with storage changes on Asset/JRiver/MinimServer automatically. JPLAY services are handled with audio detection providing smoothest experience.

Audio drivers will no longer trouble NimitraOS with over 500 latest drivers integrated providing bit-perfect playback with manufacturer’s driver as true plug and play. There’s also Teamviewer support to assist with software and driver update remotely.

 

I hope this will help you understanding Nimitra Computer Audio Server better on software improvements side. It’s not just trimmed down OS with audio optimizations but also packed with a lot of quality of life features making complexed things done simpler. 🙂

Things I realized while refactoring USB audio drivers for Nimitra server

 in Article

 

Image result for xmos audio driver

 

Today I refactored USB audio drivers for Nimitra server and update latest drivers from possible sources I found for 2019 update. While during driver update for whole night, I realized something interesting.

 

1. Many clients are computer illiterate and I often see my Fidelizer clients asking his friends to setup with driver. Companies not providing public driver support will cause a lot of trouble for their clients who don’t setup driver themselves. I’m sure they have their reasons but refusing to provide public driver download can cause clients returning products due to unexpected issues.

2. Driver download should be easily accessible. Some companies don’t provide driver download in product or support page and browsing through site’s structure to find downloadable content can make some people giving up on trying. Some companies also made a good decision to adopt single technology and make universal driver for all products which is very nice.

3. Products with more up to date drivers will take higher priority on customer’s checklist. Some used to be famous products gaining less attention due to using legacy XMOS driver version 1.61 and newer Windows 10 with updates may have strange issues for some.

 

I also saw a few companies leaving industry and some redirected audiophile website to some random shops instead which is kinda sad too. Computer audio should be easier to use with less trouble and I hope Nimitra can help getting better audio experience with passionate products.

Added EtherStream feedback from Song Soon Onn

EtherStream - Main

 

Here’s another feedback today from early Nimitra client with highend system. He ordered 2 units for his friends and shared feedback with his friend’s system in forum.

Tested EtherStream in my friend’s system consisting of expensive cables, Odin 2, CH Precision with PSU, Trinity pre & power amp. Compared to the stock Cisco switch (same as EtherStream’s stock Cisco except 5 ports), major and clearly audible improvement.

In my system with Nimitra Music server with all Vitus Masterpiece components, there was improvement but not as dramatic as in my friend’s system. Probably because his NAS was connected to EtherStream where else my SSD was connected directly to 1 of Nimitra USB port.

I did compare it streaming through Tidal. Even though it better compare to using stock switch, I prefer the SQ streaming through local files. How good is Nimitra? Not bad at all considering the price. I used to play with Aurender W20 connected to MSB Selectl. For reference.

This is just my opinion. Couldn’t believe a modified switch can make such an impact on SQ.

This is probably the first feedback from ultra highend systems with EtherStream. I’m happy to hear EtherStream making good contribution on other highend systems. 🙂

EtherStream - Main

 

Here’s a new feedback today from client who purchased EtherStream to use with Fidelizer Nimitra+Nikola server combo. He also find improvements on video streaming too.

Hi Keetakawee,

EtherStream Switch has now been in my system for a couple of weeks. The quality of hires audio streaming is dramatically improved and now very close to playing directly from SSD disk. As a welcome bonus, picture and sound quality for TV and video streaming is also significantly better. This is by far the best value for money audio/video upgrade I have ever done.

Best regards
Kjell

I’m happy to hear that he finds improvements with EtherStream as I intended to build for. EtherStream is the most effective upgrade to for streaming media applications. 🙂
