Sorry, but you didn't answer my question: can the PA-900 (or the BK-9 for that matter) achieve that sound quality? (I am talking of crispness, fullness, clarity and so on here).
If they did, I would buy one in a heartbeat, but from all the demo's I have heard so far (no matter how wonderfully played), I have strong doubts.
