i recently heard the evos playing with both aesthetix tube gear and classe ss gear. the classe was a bit much for them,just too much power and if you read any of my past posts you will see i never pick the ss over tubes in any case.lmao!!! but the aesthetix gear was awesome with evos and sounded so smooth and perfect i was blown away and they were using a really nice classe preamp with it. i was there to hear the rhea phonotage that was being sold used but loved the whole aesthetix/ evo setup it was just incredible. i even inquired if i could use these speakers with 300b amps and was invited back with my amps to try it and never did go back. id listen to joe and bruce though who have owned these speakers. best of luck!!!
