Back in Jan this year I bought a lightly used A-S2200 from here on agon. Seller was a classical guitarist who upgraded? to a Denon A110. I read all 90 pages of the Yammy AS series on hoffman forum. It's a great thread if you sort through the bs vs real audiophiles. Helom/Helomech swayed me the most there and I see he's here too. He seems to have done all our testing for us with all the swapping testing of his. His descriptions of the AS series are pretty much how I would write them too. So I'll just say "What he said" when I see his posts regarding the these amps.
The Klipsch forum seems to like the AS pairing too.
