Fidelizer Nimitra Firmware 4.0 Updater is released with Device/Sound Signature Profile options

 

Nimitra Firmware 4.0 Updater

 

It’s been a long while since last time I released Nimitra Firmware update. There’s a lot of on going internal optimizations and improvements with Nimitra after 3.0 release including new platform and supported protocols.

Version 4.0 will cover many changes and improvements on NimitraOS platform and also updater itself. Here’s summarize about major updates in version 4.0:

 

Added Device Profile and Sound Signature Profile configuration options

 

Nimitra Firmware 4.0 Updater - Main

 

Device Profile is Fidelizer Pro’s Audio Profile but I changed wording to device to avoid confusion. Nimitra will be configured as Network Player by default for general purposes but you can choose different profile for Nimitra to work with specific device better now.

For example, you can change option to Streamer for better sound quality with Network Player/Endpoint device. You can also choose Audio Player if you don’t use streaming or networked storage at all too for better optimizations.

Sound Signature Profile is a unique new configuration added in NimitraOS sound quality optimizations platform. Some clients prefer to have analogue sound reproduction but there’s also those who prefer high resolution with finer details.

You can choose sound signature of Nimitra to match with your system better. Nimitra will be configured with real sound signature profile but both options are good in different aspects so you can try both and pick what you prefer more in your system.

 

Support AirPlay, Logitech Media Server, OpenHome (Lumin / Kazoo) platform

Current models of Nimitra will have new platform integration support by default and older model can be configured to launch them too with remote support. If you want to use these features, please contact Fidelizer support for remote assistance.

 

Improved compatibility with JRiver and JPLAY7

In this update, JRiver will always scan for music in libray during startup reliably to make sure you won’t miss any new added track. JPLAY7 will also have Nimitra’s recommended configuration and optimizations on its services to be more reliable too.

 

Improved NimitraOS core sound quality optimizations and quality of life improvements

After over 2 years of firmware 3.0 update, NimitraOS has been improving with internal updates through time with clients and firmware 4.0 will bring better sound quality standards. Besides sound quality improvements, boot time is also decreased also.

 

Changelog

-Added AirPlay/HQPlayer NAA/Logitech Media Server/OpenHome integration support
-Added device profile option to optimize Nimitra device for optimal sound quality in different setups
-Added external application launcher support
-Added sound signature profile options to choose between real sound performance and audiophile sound performance
-Changed audio detection notification message to “Audio ready”
-Changed JRiver platform to always perform full library scan on startup
-Fixed JRiver startup issue on 64-bit platform running 32-bit version of JRiver Media Center
-Fixed Windows update failing to be turned off completely on some early units
-Improved compatibility with JPLAY7 and its Femto service
-Improved MinimServer optimizations to work with renderer platforms better
-Improved NimitraOS sound quality optimizations for better sound quality
-Improved optimizations with dual core processor server such as Weiss MAN301
-Improved platform optimizations code to decrease boot time
-Updated HQPlayer NAA daemon software to version 4.11

 

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 8 optimizations.

Nimitra/NimitraS customers can send request for firmware update and I’ll update Nimitra firmware through Teamviewer or request download link for applying update manually. This update is highly recommended for all Nimitra users.

Introducing Classic series of Nimitra and Nikola, the most affordable highend audio products

After successful launch of Nimitra and Nikola Signature lineup, I gained a lot of experience and knowledge about building affordable products with better price performance ratio. After a lot of design and listening tests, Classic series of Nimitra and Nikola is finally ready.

The original Nimitra and Nikola have some limitations on pricing and they reached maturity in Signature series later. Classic series has improvements and corrections on original design for 2 years optimizing to get the most from Signature series.

 

Nimitra Classic - computer audio server

 

Nimitra Classic provides full support of Roon Core and Roon Ready with many other features such as DLNA/uPNP, OpenHome (Linn/Lumin), HQPlayer NAA, Airplay, and Squeezebox ready to be used with same optimizations as Signature version with only hardware changes as below.

-Same software features and optimizations as Signature version
-Cost most effective solution for sound quality / features / services
-Compact 1.5mm aluminum thickness chassis for small space
-Cost effective motherboard design with high precision event timer
-Trusted industrial quality components with high reliability

Since audiophile network switch is becoming standards in 2020, WiFi module will not be installed by default for better sound quality. You can choose to install WiFi module if you want to. I can still setup JPLAY and others as optional requests also.

 

Nikola Classic - linear power supply

 

Nikola Classic shares the same circuit design as original Nikola. It has some parts changed and adjusted to deliver better price performance ratio with high synergy to perform well in any system musically with some changes as below.

-Same circuitry design as original Nikola
-Regulator tuned for high synergy musical performance
-Compact 1.5mm Aluminum chassis for small space
-Audiophile grade capacitors used in some flagship products
-16 AWG teflon insulated copper internal wiring

I managed to find better cost effective parts with some design changes to bring the better performing products at more affordable price. Nikola Classic will be an ideal linear power supply solution for EtherStream and many other products with linear power supply too.

 

The price of Nimitra Classic is $995 USD and price of Nikola Classic is $395 USD. All Nimitra and Nikola products will have free shipping during introductory period until 31st October 2020 with 30-day money back guaranteed.

You can also purchase Nimitra and Nikola Classic series with EtherStream with free shipping and 2 outputs termination at $1785 USD. This combination is even more affordable than Nimitra Signature server and I hope this will help making highend audio more affordable.

MAN301xNimitraOS Project – Reviving Weiss MAN301 to support Roon/uPNP/HQPlayer with NimitraOS

As some people questioning if it’s appropriate to publish this article, I reached out to Mr. Daniel Weiss before publishing this article and he’s also interested in this project too. 🙂

 

MAN301xNimitraOS - 1 - Unboxing

 

Are you Weiss MAN301 owner? Do you wish to stream Tidal/Quboz with bit-perfect native streaming rather than using legacy Airplay? Do you wish to enjoy Roon experience with great sound quality with native endpoint or even as a Roon core rather than relying on Airplay? Do you wish to try popular highend apps like JPLAY/HQPlayer with MAN301? Do you wish to stream music easily from NAS with uPNP/OpenHome/etc. rather than classic library mapping? Do you wish to try different application to browse and play music easier?

These questions are what I heard from my friends who own Weiss MAN301 and also myself for things I wish MAN301 could improve during past years. It’s been over 5 years since the last firmware update and we have no idea when Weiss will release a new major update adding Tidal/Quboz or support Roon Ready feature at least. So, today I have great news to inspire hope and possibilities to improve Weiss MAN301 and realize those wishful thinking features.

Last week I visited my friend’s audiophile shop who’s interested in my Nimitra server product. We discussed about how great DAC in Weiss MAN301 is especially Golden DAC and I told him MAN301 uses the same board I used to use on my older servers before Nimitra that sells globally. So it’s possible to setup NimitraOS with Weiss MAN301 hardware though I’m not really sure if playback to DAC will work fine as I haven’t tried yet. So, he lent his unit to me to find out if it’s possible to setup new platform to support newer technology better.

 

MAN301xNimitraOS - 2 - Entering developer zone

 

Since I want to keep original parts as is so I will test this with different storage to install new OS. At first I tried using my spare Western HDD but I later realized I could use SSD from one of my testing server which has the same motherboard as MAN301 too. Maybe mine is newer now. He already upgraded ethernet cable high quality audiophile one so I didn’t change anything else but SSD that I placed on top of original one in case it didn’t work out.

When I was going to setup for developer environment, I noticed one of the biggest issue here. This motherboard only has VGA output and it’s right behind to heat box below fan so I can’t install VGA cable at this position. I thought about removing fan and everything underneath but that’d be too risky to damage unit. After thinking for a while, I noticed PCI slot is for WiFi module so I can remove riser block to lift up some space to install VGA cable. I also placed my shirt below motherboard to avoid short circuit and damaging motherboard circuit.

 

MAN301xNimitraOS - 3 - Configure BIOS

 

OK I can boot up it and these old menus it reminded when I setup my first Xeroc server for local clients. They’re still using it with latest update I sent yearly or when someone needs update for new drivers even now. It looks like BIOS is configured with default settings so I optimized some changes in BIOS for better sound quality. If this project fails or need to send back for services, I can always load optimal defaults without worries. My VGA is worn out and rusty now so sorry for yellow screen during this journey in advance.

 

MAN301xNimitraOS - 4 - Installing NimitraOS

 

After finishing up BIOS setup, I tried to load NimitraOS installation media which took forever to boot up to Windows setup screen. I now remember why I didn’t offer Xeroc clients with Nimitra platform upgrade years back. It’s because I couldn’t load past booting screen and though motherboard didn’t support it. It seems I can actually install Windows 10 on Xeroc with more patience to wait until it finally boots up. The installation went smoothly and no issue detected during installation.

 

MAN301xNimitraOS - 5 - Checking audio devices

 

After Windows 10 finished installation, I implemented NimitraOS core optimizations and noticed that MAN301 uses firewire interface with Weiss Firewire IO Audio. When I used Weiss INT202, I didn’t see AV/C Audio and AV/C Subunit before so these are probably control modules for DAC and other features in MAN301. My main goal is to audio output working with DAC and chances that other digital inputs and device’s specific features may not work are still acceptable if DAC can function with NimitraOS.

Well, it’d be nice to get them working too so I reinstalled Weiss driver again and it appeared those missing drivers are all gone and ASIO output is added so maybe I can get more features working with Weiss Control application later. However, I came to regret my decision later and almost failed this project due to this decision.

 

MAN301xNimitraOS - 6 - Checking resource utilization

 

Now let’s check how system performance is like with NimitraOS using Weiss MAN301 hardware. Weiss MAN301 hardware has Intel D510 which is 1.67GHz dual core processor and support 64-bit architecture. It comes with Corsair value grade DDR2 RAM which is the lowest CL RAM in market but only single 2GB RAM. WiFi module is removed right now so you won’t see Wi-Fi in task manager yet. I’ll rename this PC to NIMITRA_SNDEMOW for Weiss testing project for now.

Normally it’s not recommended to install Windows 10 on very old hardware like Intel Atom D510MO with only 2GB RAM. But since this is NimitraOS with tiniest footprints for audiophile, OS itself uses only 600MB and it’ll be only around 1GB with other apps running. So even with only 2GB RAM, NimitraOS is capable of performing all features presented in Nimitra server. This project should be a good example to show how robust NimitraOS can be in extreme condition.

 

MAN301xNimitraOS - 7 - Checking applications

 

I’d like to remind you that once I put board down to its place and close the lid, I can only control Weiss MAN301 from remote access only so I shall test everything I can and setup Teamviewer remote access before finalizing system physically. It’d take a bit of effort to setup VGA output to screen again if I miss something here. I also need to setup WiFi from USB adapter in case Ethernet cable fails too.

JRiver platform worked fine and HQPlayer recognizes NAA and also Airplay and OpenHome services that I added too. Roon Ready feature is working and recognized from my PC running Roon core. I can install Roon core on MAN301 and it runs without any error report. However, I can’t run Roon software so I cannot access Roon inside remote access and need to setup from my PC instead. I tried installing latest available graphic driver though it’s older than Windows 10 but that didn’t work out due to being too old without WGL functions.

 

MAN301xNimitraOS - 8 - Checking CD drive features

 

OK. Wi-Fi network worked and I can access via Teamviewer remote. Since it wasn’t connected to audio system yet so I couldn’t confirm if playback works properly but it seems to play somehow. ASIO output failed in JRiver so maybe there’s some restriction? Teac drive in MAN301 worked fine for both playback and ripping as you can see.

There’s one tricky part about CD feature though. This Teac drive is slotin and has no eject button. MAN301 doesn’t have eject button implemented too. So, I can setup program to play or rip automatically but I can’t eject CD myself physically. I looked for workaround and it appeared I can use paid version of Unified Remote app ($5) to sync with MAN301 and tap eject button on app.

CD playback with JRiver can work but JRemote doesn’t provide CD playback control and you can only press back/forward without track number to control CD playback. I wish Roon will implement CD playback feature soon so audiophiles can enjoy their CD collection in computer audio server better. I’m still looking for good apps to recommend about CD playback too.

 

MAN301xNimitraOS - 9 - Testing Roon Core

 

After testing most features I can, I moved MAN301 to my main system and tried to play something. It was dead quiet. I didn’t mean very low noise floor but no signal at all. My worries became reality now. It could be that Weiss Firewire IO Audio may receive playback signal from PC but input receiver may not select audio source from PC nor even function. Though it’s possible to access new features for server but having non-usable DAC isn’t worth it at all.

Maybe I tinkered around audio configuration too much? I tried to uninstall and setup again with default settings but no luck. I changed from ASIO to WASAPI but still no luck though I can see playback is working. It felt like I watch Playback Designs remote that has PC function but that remote is broken. I tried everything I could think of including older driver version but all failed to make sound.

When I was about to give up, I decided to try what I saw first again. I removed all installed drivers and installed driver again on main audio one leaving two other drivers uninstalled. I used manual driver installation to do this and miracle happened. I heard music and it sounded so good. It reminded me when my friend first brought MAN301 to my home and I told him I’d buy MAN301 if I prefer this over my own server. I definitely would bought it if I had heard MAN301 like this. Original OS also sound great but it’s a bit too analytical to my taste.

 

Next day morning I informed my friends about this great news. He was overjoyed and told me now he could finally appreciate music with Roon and MAN301 using full performance. Although using CD function is a bit tricky and you can’t switch digital input anymore, having NimitraOS platform on MAN301 with its Golden DAC is like dream come true for many audiophiles in Thailand. I tried to convince every MAN301 owner here to try this project but none decided to give it a shot until now.

I’m going to bring this MAN301 with NimitraOS platform to his store this afternoon after finishing this article. If he decides to keep NimitraOS on MAN301, I’ll proceed to next levels while trying to keep original parts intact. I’ll buy Samsung 860 Pro drive and 2x2GB RAM for matching dual channel 4GB. I’ll also upgrade USB and SATA cables too. Cables used inside MAN301 is like industrial standard version so some little more upgrade won’t hurt.

I hope this project will help you guys about trying to make better use of MAN301. I always admire and respect Mr. Daniel Weiss who’s truly the first pioneer and most passionate about computer audio. I’m proud to be the first Thai customer who purchased his Weiss Minerva DAC too. I hope this project will help keeping one of his best legacy to live on through this decade and feel free to ask me if you need advice about setting up MAN301 with 3rd-party OS. Happy listening. 🙂

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

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

 

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.
