v8.0:
-Decreased PureXIntenseBLAST speaker volume to prevent distortion (Loudness is still enhanced)
-Decreased stock Speaker volume to also prevent distortion but keep loudness enhancement
-Zero Distortion
-SRS TruMedia FULLY ENABLED (Soundstage should sound more "Virtualized" with deeper bass) (System-Wide)
-Also slightly increased the headphone volume again (This time, it is not as loud but loudewr than v7.5 so i doubt you will get any distortions)

v7.5:

-Improved PureXPsychoRealism
-Improved PureXHiClarity
-Added Audio Submix Library
-Set resampling to 4 (Max value with native libaudio-resampler.so from android 4.2) (Don't assume it's bad since it's a much lower number than stock)
