I got an Odyssey Audio Dual Stratos into my system about 6 weeks ago. What a fantastic amp. This thing sounds so sweet. I have it paired up with a pair of ACI 25th Anniversary Sapphires and an ACI Titan II sub. In the future, when I finally find the right house, I am going to go to at least a 5.1 setup, possibly a 7.1. Either way, I want to get a 5 channel amp to mate with this one because I want the possibility of future 7.1 upgrade even if it's not immediate. Odyssey doesn't make a 5 channel amp, and I don't want three boxes, so I am looking at other 5 channel amps. Amongst those I am considering are... Classe CAV-180 Aragon 8008x5 Bryston 9B-ST Sherbourn 5/1500 I was looking for other suggestions and opinions on which of these would match up the best with the Odyssey and ACI speakers, both of which are highly detailed and slightly on the warm side of neutral, but more neutral than warm. Thanks. Right now I am leaning towards the Aragon based on reputation only, but there is not one available on Audiogon at this moment. Thanks again.
