Since many people asked for Gaplass and fixing Poweramp stuff, I decided to lower the bar for people who want it. This is 'hardly' Purist but that's as far as I can do to keep up with compatibility request. True purist ROM will have the following features:
1. audio effect engine removed completely
2. Equalizer/Gaplass/ffmpeg components removed from core audio engine
3. I/O optimizations will be optimized for lowest possible latency with stable sonic performance
That's what true purist looks like and it'll still be available for customers who purchased Advanced ROM from me together with compatibility version.
And million thanks to Paul for answering our prayers. I also have DX200 modification service (ROM and hardware modification) for people who're interested in taking this to the further levels.
