PerfectDynamics 2.0 Sound Optimizations will be introduced in Munich 2018 AV Show

 

Fidelizer - PerfectDynamics Sound Optimizations

 

PerfectDynamics technology is device-specific optimizations for Enhanced / Advanced ROM introduced on 1st October 2017. In upcoming Munich 2018 AV Show, I’ll introduce PerfectDynamics 2.0 with iBasso DX200 and Fiio X5iii device.

During development of PerfectDynamics’ initial version, iBasso DX200 and Fiio X5iii didn’t get the better sounding version of firmware and they later improved in over time. After I tried DX150 2.9 firmware port on DX200, I feel it’s ready to take this to the next level.

Having good sounding firmware to optimize is very important because sometimes you can’t be sure whether this optimization will really improve over all performance or just compesate the flaw with firmware itself. Even now I’m still not sure that I can finish it before the show lol.

 

PerfectDynamics 2.0 Goals:

-Fix random crash and reboot in some scenarios (90% – Fixed stability issues with boot image optimizations)
-Decay, depth and imaging will be important than clarity and separation (60% – Tuning I/O optimizations)
-Transient dynamics will have improved linearity which will also reduce digital glare effect (40% – Tuning PerfectDynamics specific optimizations)
-Full sound reproduction will take higher priority than making audio sounding pure (40% – Tuning audio optimizations)

 

If I can archive all that, PerfectDynamics 2.0 will make Linux based audio performance becoming closer to Fidelizer’s optimizations in Windows. I’ll start working today on iBasso DX200 first and I hope to master PerfectDynamics 2.0 before the show. 🙂

Fidelizer’s first show in Munich 2018 with NimitraS and portable products

 

Fidelizer Munich 2018

 

When I first launched Nimitra, I told myself that some days I’ll demonstrate my products in Munich which is the world’s largest HiFi Show. And today I’m happy to tell you that I’m going to realize that dream in this year’s Munich Show.

 

Please come and visit us in Hall 3 Booth J15 and meet:

Fidelizer Audio
MA Recordings
Analog Magik
BlackCat Cable
Fern and Roby Audio

In Fidelizer Audio booth, you can listen to

NimitraS Computer Audio Server
Nikola Linear Power Supply
Fidelizer Mod for DX200 / X5iii / Mojo
Upcoming Fidelizer Mod for headphones

 

I’d like to express my thanks to Mr. Todd from M.A. Recordings and all vendors in Thailand who supported us. We’ve known each other for a few years during HiFi Show in Thailand and Hong Kong.

This year we decided to exhibit our products in the show together so you can listen to his music with Fidelizer systems and I hope to do this again in other international shows in years to come. 🙂

iBasso DX150 is now added into Fidelizer Purist ROM repository with PerfectDynamics optimizations!

 

Fidelizer - PerfectDynamics Sound Optimizations

 

I heard the first DX150 ROM was released when I was coming back from visiting my parents during Songkran new year in Thailand. I was little worried about working on OTA ROM without factory image but I managed to make it work in the end. This won’t wipe your data too so enjoy. 🙂

-Based on firmware version 2.9.250
-Play Store added
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-Revamped MangoPlayer UI with improved user experience
-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 (Poweramp works now)

Download: iBasso DX150 Purist ROM

 

Installation Guide

1. Download Factory Tool provided by Paul http://www.ibasso.com/uploadfiles/download/FactoryTool_v1.39_DX200.zip
2. Turn off DX150
3. Connect DX150 with USB connection to computer while holding play button switch
4. Install Rockchip USB driver included in FactoryTool
5. Open FactoryTool.exe and flash ROM according to instructions provided in DX200 batch tool instruction.doc

For Mac / Linux users, please check this guide for flashing Fidelizer Purist ROM on Mac / Linux instructions.

 

I also tried flashing DX150 files on DX200 and it works too so you may expect unofficial port for DX200 soon. Please read Portable Products for more details about Enhanced and Advanced ROM and let me know if you’d like to apply Fidelizer Mod too. Happy listening. 🙂

Introducing NimitraS (Signature Upgrade) as premium upgrade version at $1,895 USD

 

NimitraS

 

Hello everyone. Today is the first day that Fidelizer Ad should start showing up on Stereophile and AudioStream website. I also have another big announcement today about Nimitra updates after launched for about 2 years now. It’s called NimitraS for Signature upgrade.

I’ve been building a few custom Nimitra servers for a long while and right now I have some custom servers in production too. Every customer who compared it with standard Nimitra saying it sounds so much better and it want me to upgrade Nimitra so much.

Don’t get me wrong. Nimitra is performing exceptionally good for its price as you can see in reviews with unique optimizations I put on. However, it’s the most affordable product I can build which mean I can build much better ones as well.

After 2 years building custom version of Nimitra, I can see the price / performance for various parts for my clients and making product with such quality won’t be affordable anymore. However, it’s possible to improve Nimitra to perform better while still being affordable enough.

After research and development for price / performance ratio, the final price for upgrade to NimitraS is $1,895 USD with the following features.

 

NimitraS (Signature Upgrade) Features:

-SSD Storage is upgraded with SLC grade as the highest quality of SSD design
-RAM is upgraded with premium grade for better audio performance and reliability
-Capacitors in motherboard upgraded with ESR lower than 10mOhm and have 5000hrs lifespan
-Blue USB ports has clock upgraded with 1.3ps phase jitter with shock / vibration resistance

 

Nimitra customers can send unit back to apply NimitraS upgrade at $500 more meaning there’s no upgrade fee to upgrade from Nimitra to NimitraS. Fidelizer will provide free shipping during introductory period for all Nimitra purchases in April 2018.

NimitraS will also come with next generation of Fidelizer Nimitra optimizations. I’ll release firmware update for standard Nimitra soon too so stay tuned and happy listening. 🙂

Fidelizer 8.1 released – First update with many fixes and improvements together with 2,900th license purchase offer

 

Fidelizer Pro

 

I hoped to release version 8.1 before Valentine’s day but there were more cases to be resolved related to security having a few internal changes until it’s more stable enough.

While fixing reported issues one by one, I also was flooded with over 100 mails per day in during the first week of Fidelizer 8 release so fixing every reported issues took me longer than expected but it’s finally done now.

New features such as Core Isolation policy and execution with music player application are working properly now. I also found core affinity optimization didn’t work properly with new algorithm so I fixed that too.

I also improved permanent optimizations in Fidelizer Pro with rounding technique. Fidelizer Pro analyzes RAM calibration with 250MB block. If system detects 3.93GB with 64MB for VGA, RAM calibration will apply optimizations as 3.75GB.

With nearly 200MB miscalculated, audio tasks won’t perform according to ideal optimizations with tonal shift. By adding rounding technique with 125MB threshold, 3.93GB RAM will be treated as 4.0GB which is closer to ideal case.

Changelog for version 8.1
