Help on integrated amp?

Of those you mention, the Classe would be the best choice, by far, for sound quality and system matching. I like the Bryston B60 very much, I owned one, but it is very revealing and I think a terrible match with the Theils. Also, at sixty watts, I am not sure it would allow them to be at their best. The best I ever heard Theils sound, was in a showroom, connected to Classe seperates. They were connected with all Nordost cabling, which, to be honest, surprised me. This was at Lyric Hifi, in N.Y.

classe is your best choice. Theils can be a little birght at times so matching it with the classe will give you a very natural presentation.

Also listen to the Audio Refinement Complete (made by YBA).
