iBasso DX200 Purist ROM version 2.9.209 released!

 in News

 

DX200 - Purist ROM

 

I thought I’d release DX200 2.9 ROM together with PerfectDynamics 2.0 but sadly I haven’t finished it yet especially after listening to classical concert in Golden Hall. There’s a lot for me to do to improve Purist ROM for 2.0 release.

However, I managed to fix a few issues during development so I’ll also include those fixes into this release too. I apologize for the issues that happened with some cases in Enhanced / Advanced ROM and now they’re all resolved. 🙂

 

-Based on firmware version 2.9.209
-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)

Fidelizer Enhanced / Advanced ROM updates for DX150 / DX200 / X5iii / X7 / X7ii

 in News

 

Portable Products

 

I posted about finishing PerfectDynamics 2.0 before attending Munich Show before. There were some progress but it’s still not considered as ready for PerfectDynamics 2.0. So I’ll release bugs fixing version instead.

As some people reported about random stability issues, I later find out that some native apps are relying on debugger and log services for I/O exception handling. Removing those services will result error beyond handling and cause system reboot.

These symptoms doesn’t happen with everyone so if you’re using Enhanced / Advanced ROM without any issue, you won’t need this update. If you have some issues that doesn’t happen with free Purist ROM, you can ask me for sending new ROM update.

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

 in News

 

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. 🙂

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. 🙂
