Thanks all for your input. I sent the Van Alstine back for a refund.
The Set control amp 120 produces a fine detailed sound and all the other things the reviews have stated. I returned it because it's not the right amp for me or perhaps it didn't pair well with any of my 4 pairs of speakers. Klipsch Forte 3, Kg 1.5, Monitor Audio Bronze 2, and Ascend Acoustic's Sierra towers with raal ribbon tweeters.
Frank and the rest of the folks at AVA were kind and gracious and made the return easy.
