Fiio X5iii Purist ROM version 1.2.5 V2 released with jkbuha’s kernel and improved PerfectDynamics 3.0!

Fidelizer - PerfectDynamics Sound Optimizations 3.0

 

For new users, please read about PerfectDynamics 3.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

 

It’s been a long while since last update of Fiio X series and I haven’t finished rolling PerfectDynamics 3.0 yet due to finalizing the improvements on legacy devices. There’s stability and sound signature to be addressed.

Finally I managed to replicate similar improvements on Oreo ROM with octa core. I tuned background tasks running on FIFO similar to R2R design and that can provide more linear sound and transparency with right tuning.

I also improved deodexing and re-basing ROM again from scratch to make sure it will be glitchless and updated Fiio Music with latest version V3.0.3 with new custom kernel from jkbuha. I’ll roll new updates for X7 and X7ii later soon.

 

-Based on firmware version 1.2.5
-De-odexed for better ART runtime optimizations
-PerfectDynamics 3.0 Sound Optimizations applied
-Kernel is replaced with jkbuha’s custom kernel
-Fiio Music app V3.0.3 updated with Fidelizer optimizations
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)

Highend-AudioPC is temporary removed from authorized distributor due to inactivity

 in News

I received inquiries form some clients since last month about ordering Fidelizer products from Highend-AudioPC but didn’t receive any response. I tried to reach out to staff for updates about order but no message was sent back to my email or inbox in online communities.

Phil is a great friend and our last exchange  was on 10th May talking about how Munich got cancelled again and he was looking forward to visit Munich in September 2021 and also covid situations. It saddens me to make a decision like this it’s been 1 month already since I last heard from him.

So, I’d like to clarify that Highend-AudioPC doesn’t have active staff to respond to orders and all transactions purchased there are not forwarded to respective manufacturers yet. As a result, I’ve removed Highend-AudioPC from authorized distributor until they can resume their business.

I apologize to all customers who ordered Fidelizer products from Highend-AudioPC and still haven’t received items and I’ll do my best to get in touch with them to resolve these issues in anyway I can. You may consider cancelling order and claim your refund too if it’s still within refund period.

I hope Phil and his family is still safe and sound during covid situation. It’s unusual for him to disappear suddenly without notice and I hope to hear back from him in good health.
