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

 

After launching PerfectDynamics for iBasso DX200 which is my reference unit, now it’s time for the most popular DAP Fiio X5iii to receive PerfectDynamics 2.0 Sound Optimizations update.

Since X5iii has Lollipop 5.1.1 ROM, it doesn’t have CPU Set concept which was introduced in Marshmallow 6 ROM, I made other adjustments to help instead. Background tasks will gain more CPU share but real time process will be minimized for quad core. 🙂
