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

 

I’ve been trying to update PerfectDynamics 2.0 update on iBasso DX50/80/90 for a long while. Whenever I tried to start updating one, new ROMs and updates keep coming out. So after porting iBasso DX220 ROM to DX200 device, I decided to finish this update.

There’s still iBasso DX100 left which I will need to test with actual device (like I did on this update). iBasso DX150 will also receive DX220 ROM port soon too so stay tuned. 🙂

If you still use good old iBasso DX50/80/90, 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. 🙂
