I think it was quite an airy detailed sound which is good, but it didn't seem to have the bass depth but possibly that could be due to hearing 25-21 not my 25-23 which are deeper. Also environment. But i think avm are good, but my thinking was to match the value of amps to the speakers, at least, to get best out of pmc's as given you can get loads more out with better amps. So I'd be going for better amps if buying these £3k speakers. The pmc guys say that avm, like bryston, is a very detailed sound. So I think that's a good thing to do (I would) as with me using Cyrus stuff which is also detailed. Nice balance with the bass Rich smooth pmc's, and detailed electronics.
