I'm using an Electrocompaniet AW120 right now. It sounds really good. I was always a tube guy, so I need that richness in the midrange, which EC stuff has. I almost bought the EVo, but was discouraged by a Talon / Bel Canto dealer who said that the EVo has the typical solid state thin midrange (by a tube lover's standards anyway). I might try a low watt SET. These things are very efficient. I use a PS Audio 600, and it hardly shows any current at all to drive these speakers. I hear that they are very good with SETs. Any experinece with that, Philefreak or Acuujim?
