Post [Q] Which ROM has a large audio buffer for non glitchy music?

I'm currently running AICP, and have a glitchy audio problem which appears to randomly pop up in some ROMs but not others. I have put this down to the audio buffer, and it appears this must be the issue as using an app to determine the size of the buffer I have found that my Desire Z's is over twice the size so, despite having far, far, lower specs, can play audio without any glitches.

My question is which ROMs have a larger audio buffer (unless its kernel related) and can I change the audio buffer size (I know you can using PowerAmp, but I want to play music on Spotify, etc. and I prefer Apollo and GPlay Music)?

Thanks in advanced
