PerfectDynamics Sound Optimizations 2.0

 

Aside from being the first stable Oreo ROM in market, DX200 is also the first device to receive PerfectDynamics Sound Optimizations 2.0 update. I was working on a new breakthrough in Nimitra firmware 3.0 update so I decided to release PerfectDynamics 2.0 later with new improvements as below.

 

System stability improvements

Back in older days, system optimizations started from raising priority, reducing buffer and other optimizations that can deliver better purist performance. With new changes in this release, it also improve system stability too.

Sound optimizations re-calibrated based on Nimitra firmware 3.0 update

I re-calibrated PerfectDynamics optimizations again to deliver real sound performance like no Linux audiophile server could ever archive before based on Nimitra firmware 3.0 update. You can feel uncompressed dynamics improving micro details and imaging with great musicality and liquidity.

Fidelizer’s Core Isolation optimizations on Linux-based platform

The first PerfectDynamics ROM was released in October 2017 before Fidelizer 8. After releasing Fidelizer 8, I tried to implement its core isolation principles to Purist ROM and this is the first ROM with Fidelizer’s core isolation applied.

CPU Sets - Oreo

CPU Sets - Fidelizer

With Fidelizer’s core isolation optimizations applied in Purist ROM, the result was truly magical. It sounds like all instruments used to perform in small room and now they’re performing in great hall that each instrument can have its own optimal space.

PerfectDynamics 2.0 features are exclusively available for Fidelizer Enhanced / Advanced ROM only. Free Purist ROM version has only generic optimizations that can safely apply to all devices so it won’t have PerfectDynamics Sound Optimizations.

 

If you like improvements in Purist ROM, you may upgrade to Enhanced / Advanced ROM for even better sound. Please read Portable Products for more details including iBasso DX200 Fidelizer Mod project with 3 modification levels and happy listening. 🙂

iBasso DX120 Purist ROM version 2.2.42 re-released!

 

Fidelizer - DX120

 

After DX120 Purist ROM was released for a while, I received one report from free Purist ROM user that he couldn’t flash Purist ROM and get it working. So today I went to my friend’s store and bought a new DX120 DAP to test. I opened it and then flash Purist ROM immediately and it worked fine. 🙂

 

-Based on firmware version 2.2.42
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
-Bundled audio effects removed but keep main engine

 

Download: iBasso DX120 Purist ROM

 

Installation Guide

1. Extract update.img from archive and copy to root directory of micro SD card and put in DX120 slot
2. Open device Settings > Advanced > System Update
3. Wait for device to finish flashing
4. After flashing is completed, you should see Fidelizer Purist ROM boot animation indicating successful update

 

I said re-released because this release contains no changes but I decided to rebuild all packages and tested with real DX120 device again just to be sure. I also did some listening tests and I prefer “Slow” filter with “Original” sound mode personally.

There’s a lot of improvements for Advanced ROM and I also added Enhanced ROM into collection too. Please read Portable Products for more details including Fidelizer Mod project with 3 modification levels. Happy listening. 🙂
