Fiio is odexed ROM and support ART runtime so I deodexed the ROM to make best uses of ART runtime improve transparency and imaging. However, stock buffer stage opamp are tuned for odexed file making sound too bright in some systems.

It’s not Fiio’s fault with their choice of buffer stage opamp doesn’t have sound signature matching with deodexed ROM. To resolve this case of incompatibility, I adjusted Fidelizer Mod level to upgrade opamps first in Reference and capacitors in Signature level.

I also made some adjustments to Chord TT product. Chord Hugo TT is more like battery powered home component so replacing 3.5 with 2.5 won’t be necessary so I chose to apply internal damping tweaks to improve device’s performance instead.

These changes won’t affect any client who applied FIdelizer Mod for Fiio X5iii before so they won’t need to send device back for adjustments. I’ll release non-deodex ROM updates for Fiio devices shortly later.
