Here’s a new feedback today. He shared his feedback after assisting him setting up Fidelizer Pro in his computer as below.
I think stereo increased 2000 usd in quality. You have a great product. Never knew PC properties could improve audio quality so much. Congratulations.
I’m glad to hear that Fidelizer Pro can bring $2,000 USD worth of sound quality improvement in his system and happy listening. 🙂
For new users, please read about PerfectDynamics 3.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

-Based on iBasso DX200 firmware version V1.10.120
-PerfectDynamics 3.0 Sound Optimizations applied
-iBasso Music, Launcher are ported from latest version of iBasso DX160 with optimizations
-Libraries files are updated from latest version of iBasso DX160
-Google Play Store added
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-MangoPlayer app has optimizations applied
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
Download: iBasso DX200 Purist ROM
Installation Guide
1. Install Rockchip USB driver included in iBasso DX220Max Upgrade Tool and make sure it shows ‘Found One ADB device’ in AndroidTool software
2. Extract OTA ROM from Official Oreo ROM firmware to DX160’s internal storage and flash from Settings > System > Updater > Local storage
3. After successfully flashing official ROM, go to Settings > System > About tablet and tap “Build number” for 7 times to enable “Developer options”
4. Tap back arrow to enter “Developer options”, enable “USB debugging”, and press OK
5. Connect DX160 to computer with USB connection in Android mode again and press OK to allow USB debugging
6. Download Disable Verity package and run disable_verity.bat file to disable verity and restart (Authorize USB debugging on device and run again)
7. After DX160 boots up properly with Verity disabled, run reset_loader.bat file so you can enter loader mode

It’s been a while after last Purist ROM. I have some time to release DX220MaxPort for iBasso DX220 device with new updates from iBasso DX220Max DX160. Enjoy. 🙂

Here’s a new feedback today. He shared his feedback after helping him setting up Fidelizer Pro with Audirvana Studio.
Thank you for your support. Now Fidelizer automatically turns on Audirvana Studio and the sound is much better.
I’m happy to hear that Fidelizer Pro can help Audirvana Studio sounding much better. Fidelizer Nimitra also works with Plays with Audirvana too. 🙂
I received report about Fidelizer causing very slow performance on computer and after inquiring about his computer’s specs, I found out he’s using modern Intel processor with efficient core.
By default configuration, it shouldn’t slow down his computer with recent changes to handle non-audio process with more processors but since I have no experience with Intel’s processor with efficient core myself, I bought one to investigate.
This MSI Cubi 5 has Intel Core i3-1215U processor. It has 2 physical cores and 4 efficient cores with 8 total threads including 2 logical cores. I assembled this NUC with good quality parts and setup Windows 11 to test since most modern PCs start to adopt Windows 11 now.
After initial setup, I found some issues related to Teamviewer 11 in Windows 11 that fails to work after applying Fidelizer Pro at maximum user level. I’ve applied internal fixes now and will release an official update later after investigation. For now, let’s see how Fidelizer handling non-audio process.
It looks like Fidelizer doesn’t detect hyper threading function on this computer. Since processor design is changed from having logical cores at double amount, I’ll revise hyper-threading detection in next update to improve performance with efficient cores.
As you can see, only CPU0 is not used in non-audio process. CPU2 and CPU4 shouldn’t be picked too if hyper-threading is active but this should confirm that Purist user level with default configuration shouldn’t affect system performance being so slow.
Now, let’s check how core affinity works after picking “Enforce non-audio process to use only one core” option too.
It uses only one last core and that’s efficient core which is less powerful than physical core. No wonder why system is very slow after using Fidelizer Pro at Purist user level with this option. For now, please don’t check this option if you don’t want your system to be very slow and unstable.
I’ll release Fidelizer 8.11 to address the reported cases with efficient cores and resolve issues with Windows 11 soon. I’ll test a bit more and find out if there’s any other issues to be resolved for Windows 11. I recommend Windows 10 for better audio performance and reliability if possible.
