It's interesting that on the ProSoundWeb forums, almost every post knocks the PAS, calling it a scam....
For keyboard info, I trust the guys on Synthzone.
For audio, I am leaning to put more trust in the guys at ProSoundWeb.

Anyone want to attempt to explain the EXTREMELY different viewpoints on this system

It's almost as if each forum has its own culture!!
