Fidelizer - PerfectDynamics Sound Optimizations

 

Hi. After working constantly on Fiio ROM updates, there’s also DX150 release for ROM version 2.10.275 too. Now DX150 Purist ROM update is ready to install with some new adjustments and improvements based on recent Fiio updates.

Right now I’m working on proper DX200 ROM update. They seem to make some major changes in kernel and changes I usually apply didn’t work on DX200 2.9. First release has issues with some cases in Mango but that’ll be fixed soon.

Added X7ii Advanced ROM feedback from Eduard-Catalin Tudor

Fidelizer Mod

 

Here’s another feedback today. I received feedback for both Fidelizer Pro and Fiio X7ii so I’d like to share them both at the same time.

Purist ROM Advance upgrade is worth every penny. It reveals more details, a more natural timbre, realistic tempo and stage. Both Fidelizer versions, ROM and PC are probably the best and and probably the last improvements I had to consider for the ultimate SQ I might need. I’m really happy with what I got for such a reasonable price. Again, I feel the need to send you beer … Cheers

I’m happy to hear Fidelizer products making a reasonable upgrade for you and thank you for supporting Fidelizer and your extra tips for beers too. 🙂

Fiio X5iii Purist ROM version 1.2.1 released – Bright sound signature is now fixed with as Odexed ROM

 in News

 

Fidelizer Mod

 

Sorry for the long delay. I was visiting my parents since last month and I didn’t bring my ROM cooking materials with me. I only got back to my place few days ago and started cooking new Fiio ROMs as soon as possible.

As some people reported and mentioned in forums about Purist ROM sounding brighter than stock ROM, it was caused by de-odexing ROM which is a common practice for ROM cooking with ART runtime.

Odexed file is compiled as Dalvik byte code so app will run through Dalvik VM. De-odexing ROM will allow ART runtime to run app natively which also improve transparency and resolution in audio too.

However, opamps used in Fiio devices tend to sound brighter so de-odexing will make those characteristics more revealing too. I will publish odexed ROM so it won’t change sound signature on stock unit and use de-odexed ROM for Fidelizer Mod version.

iBasso DX200 Purist ROM version 2.9.209 released!

DX200 - Purist ROM

 

I thought I’d release DX200 2.9 ROM together with PerfectDynamics 2.0 but sadly I haven’t finished it yet especially after listening to classical concert in Golden Hall. There’s a lot for me to do to improve Purist ROM for 2.0 release.

However, I managed to fix a few issues during development so I’ll also include those fixes into this release too. I apologize for the issues that happened with some cases in Enhanced / Advanced ROM and now they’re all resolved. 🙂

Fidelizer Enhanced / Advanced ROM updates for DX150 / DX200 / X5iii / X7 / X7ii

 in News

 

Portable Products

 

I posted about finishing PerfectDynamics 2.0 before attending Munich Show before. There were some progress but it’s still not considered as ready for PerfectDynamics 2.0. So I’ll release bugs fixing version instead.

As some people reported about random stability issues, I later find out that some native apps are relying on debugger and log services for I/O exception handling. Removing those services will result error beyond handling and cause system reboot.

These symptoms doesn’t happen with everyone so if you’re using Enhanced / Advanced ROM without any issue, you won’t need this update. If you have some issues that doesn’t happen with free Purist ROM, you can ask me for sending new ROM update.
