Glory,
Thanks for the feedback. I do not doubt there is a lot of difference between the 30 and 30.2. I also don't doubt that it's a superb amp. However, I'm rather confident I'd still prefer SET, especially given your comment that tonality is not quite up to par. That is #1 in my book.
(FYI - It turns out I have a dealer 1 mi from me carrying the new Zu speakers - so I can hear them first-hand.)
