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

Finally, PerfectDynamics 2.0 update for iBasso DX100 is released. This device is very old so it needed specific methods to build this ROM to work properly. I also updated flashing instructions in DX100 Purist ROM based on recent tests.

I finally finished completed PerfectDynamics 2.0 line up now. DX200 ROM update was released yesterday so I’ll try to release an official one first with MangoPlayer from DX220 device . 🙂

If you still use good old iBasso DX100, you can check out Fidelizer Purist ROM first and see. If you’d like to upgrade with PerfectDynamics Sound Optimizations in Enhanced / Advanced ROM, there’ll be a lot of improvements that won’t disappoint those who can appreciate Purist ROM. 🙂

I was told new DX200 ROM is out now but allow me to release this first. In my early days of Android ROM optimizations, I got a chance to try optimizing DX100 ROM for my client once but couldn’t get the optimized ROM working due to my inexperience.

I recently got another chance to try on iBasso DX100 firmware again. Now I know more about Android and Linux so I can optimize both boot and system image without corrupting it. DX100 is quite slow with Gingerbread and Fidelizer Purist ROM helps a lot.

After modifying DX100 firmware, the client himself told me he’ll apply Fidelizer Ultimate Mod for completed hardware upgrade next. I also modified AK380Cu last week and have few more DX200, AK380Cu and Opus#2 to work on so this will take a while. 🙂

-Based on firmware version 1.4.2
-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)
