For new users, please read about PerfectDynamics 2.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

 

Hi guys. Fidelizer Purist ROM update for iBasso DX120 ROM version 2.9.121 is out now. It’s a bit confusing to choose between 2.9.121 and 2.9.122 release but they both are actually the same ROM so I believe official version is 2.9.121 one. 🙂

-Based on firmware version 2.9.121
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
