Unfortunately, i didn`t like the brand-new v3 beta-preview-build-790 on my Sony Xperia Z2 (Android 6.0).
The previous build 703 was awesome: minimalistic GUI, detailed audio processing info and the main - great sound quality with SONY Hi-Res Output - 24 bit/48kHz SoX Resampler 95% Cutoff DVC No EQ.
But now, it seems like the option No EQ doesn`t work properly on my device: sound is very bass busting with lack of details. I know that sound engine is the same for 703 and 790 builds. I don`t know why it is but when I downgrade to 703 it sounds much better. Maybe there are some compatibility issues with Android 6.0 and 790 build.
I hope next builds will be better. Anyway thanks a lot for development of Poweramp.
