Fiio X5iii Purist ROM version 1.1.8 released with PerfectDynamics Sound Optimizations!

 

Fidelizer - PerfectDynamics Sound Optimizations

 

For new users, please read about PerfectDynamics Sound Optimizations first for new improvements with Fidelizer ROMs.

 

Before introducing PerfectDynamics update, I tested PerfectDynamics Sound Optimizations with iBasso DX200, Fiio X5iii and iBasso DX90 to confirm my theory. However, launching new ROM updates requires more testing and I found some issues to work on since last week.

When I left X5iii playing with repeat, I found it stopped playing after few tracks. I also added other optimizations for Fiio itself too so finding which tweaks caused this issue took me a lot longer than I expected and now it’s finally fixed and stable for whole night music.

-Based on firmware version 1.1.8
-Deodexed
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)
