Sorry to be so late to this thread, but I have owned several SET amps (and love them), and was smitten by the Robert Harley review of the Berning 211/845 monoblocks that I bought a pair. Dang if they didn't just smoke my previous favorite amp (SET), not to mention the 4 other amplifiers in house. I play them through a pair of Avantgarde Duo XD speakers, and the Berning monos have all the things I've come to love about SETs: Crazy good dynamics, the timbre that says the artists are in the room, just right warmth, majesty when needed (Mahler) and intimacy when needed (piano trios). They simply sound live. Well, the Berning was the first amp to give me that plus have more power and an effortless-ness missed by the SETs in big passages, and WAY better than any solid state amp I've used, despite their power. Anyway, there is a used pair out there for sale, FYI.
