I have owned 5 different models in the Thiel line and I would strongly recommend Classe. They have a "Tube" like sound and are very warm sounding. The have lots of power and are very well built. I have never had them be fatiguing at all. My ecpierence with Adcom is that thry are under powered compared to Classe and they feel and look cheap. Bryston to me sounds thin and unimpressive, weak, I.M.H.O. If you look back thru reports from HiFi shows you will find Thiel, Classe and MIT alot, and they are always considered to be a good combo. Anyway ,Good Lucl to you!
