Added testimonial from Eric McDade

Here’s another feedback today. He uses Fidelizer Pro in dual PC setup with DSD512 upsampling to T+A DAC8 DSD.

Hi Keetakawee,

I just wanted to say thank you for this wonderful software! I started out just using one installation on the “streamer/endpoint” PC in my listening room. I upconvert all files to DSD512 to feed a T+A DAC 8 DSD. Since I started doing this conversion, and while I have a powerful server, other processes and programs would sometimes interfere and cause skipping and stuttering during playback. After installing Fidelizer Pro on my server today, I can attest that I haven’t had a SINGLE hiccup of skipping, stuttering, etc.! Track switching is faster now as well. And I got ANOTHER little boost in sound quality.

So happy that my setup is completely headache free now, and sounding better than ever.

Thanks again,

Eric McDade

Fidelizer will deliver sound quality and audio performance improvements effortlessly to help you enjoy the music better than ever. 🙂

Extreme dual PC computer audio setup shootout between AudioLinux and Windows Server 2019

 in Article

I’ve been exchanging ideas about computer audio improvements with my pals for a long while and recent he started doing some very serious shootout between the best of Linux today “AudioLinux” and “Windows Server 2019” with software optimizations.

I’ve been checking out in forums recently and it seems there’s only good thing about one thing and the another but never see anyone posting about direct competition. So I asked him if I can share his test results in website and he said it’s OK.

 

The test was performed with AudioLinux with the double PC. Server with Xeon optimized with Roon Server and music on NAS and the renderer on Celeron with Roon Bridge, both started by pen drive and then put in ram without disks in headless extreme mode.

Good sound tonally correct, but lacking body and less broad and deep, thin sound and long tiring, compared to my current type configuration based on a single PC with Windows Server 2019 core with the new JPLAY 7 and Fidelizer 8.2, NAS with MinimServer commanded by mConnect.

Sound warmer round, analog with more body and that projects you more in the sound event, in short, the sound of Linux I do not like. Put Linux both in ram has not had positive effects the sound of Linux is always exile, lack of harmonics compared to Windows.

 

This is a serious shootout in extreme dual PC setup environment. AudioLinux is only $50 and should do pretty well for its price. I hope the future of Linux-based OS will be bright for those who don’t mind paying for products and services in near future. 🙂

32-bit VS 64-bit audio playback – Can you spot the difference?

 in Article

After JPLAY Femto released with 64-bit only, some Nimitra clients asked me about reinstalling 64-bit version of Nimitra since it was shipped with 32-bit before so I decided to make a clip for clients to compare and see if they can hear the difference.

These two tracks are recorded from the same physical hardware with dual boot to 32-bit and 64-bit OS version with Audacity software using WASAPI and Razor Siren X through JCAT USB Card Femto + NikolaS. I also use 64-bit application for audio playback in 64-bit OS too.

PerfectDynamics Sound Optimizations 2.0

 

Aside from being the first stable Oreo ROM in market, DX200 is also the first device to receive PerfectDynamics Sound Optimizations 2.0 update. I was working on a new breakthrough in Nimitra firmware 3.0 update so I decided to release PerfectDynamics 2.0 later with new improvements as below.

 

System stability improvements

Back in older days, system optimizations started from raising priority, reducing buffer and other optimizations that can deliver better purist performance. With new changes in this release, it also improve system stability too.

Sound optimizations re-calibrated based on Nimitra firmware 3.0 update

I re-calibrated PerfectDynamics optimizations again to deliver real sound performance like no Linux audiophile server could ever archive before based on Nimitra firmware 3.0 update. You can feel uncompressed dynamics improving micro details and imaging with great musicality and liquidity.

Fidelizer’s Core Isolation optimizations on Linux-based platform

The first PerfectDynamics ROM was released in October 2017 before Fidelizer 8. After releasing Fidelizer 8, I tried to implement its core isolation principles to Purist ROM and this is the first ROM with Fidelizer’s core isolation applied.

CPU Sets - Oreo

CPU Sets - Fidelizer

With Fidelizer’s core isolation optimizations applied in Purist ROM, the result was truly magical. It sounds like all instruments used to perform in small room and now they’re performing in great hall that each instrument can have its own optimal space.

PerfectDynamics 2.0 features are exclusively available for Fidelizer Enhanced / Advanced ROM only. Free Purist ROM version has only generic optimizations that can safely apply to all devices so it won’t have PerfectDynamics Sound Optimizations.

 

If you like improvements in Purist ROM, you may upgrade to Enhanced / Advanced ROM for even better sound. Please read Portable Products for more details including iBasso DX200 Fidelizer Mod project with 3 modification levels and happy listening. 🙂

iBasso DX120 Purist ROM version 2.2.42 re-released!

 in News

 

Fidelizer - DX120

 

After DX120 Purist ROM was released for a while, I received one report from free Purist ROM user that he couldn’t flash Purist ROM and get it working. So today I went to my friend’s store and bought a new DX120 DAP to test. I opened it and then flash Purist ROM immediately and it worked fine. 🙂

 

-Based on firmware version 2.2.42
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
-Bundled audio effects removed but keep main engine

 

Download: iBasso DX120 Purist ROM

 

Installation Guide

1. Extract update.img from archive and copy to root directory of micro SD card and put in DX120 slot
2. Open device Settings > Advanced > System Update
3. Wait for device to finish flashing
4. After flashing is completed, you should see Fidelizer Purist ROM boot animation indicating successful update

 

I said re-released because this release contains no changes but I decided to rebuild all packages and tested with real DX120 device again just to be sure. I also did some listening tests and I prefer “Slow” filter with “Original” sound mode personally.

There’s a lot of improvements for Advanced ROM and I also added Enhanced ROM into collection too. Please read Portable Products for more details including Fidelizer Mod project with 3 modification levels. Happy listening. 🙂
