Right now I'm using my SET 120 (standard, not Control) with the new Mission 770 and the results are outstanding. Previously the amp was on Spatial Audio M3 Triode Masters as well as Falcon Gold Badge LS3/5a -- both excellent pairings. The only speakers that were not a good match for me -- and I don't mean to cause controversy -- were the Magnepan LRS+. Maybe it was the room, maybe I just don't care for Magnepans, I don't know. But the pairing didn't work for me at all. But before I get roasted here, let me be clear, I kept the SET120 because it's brilliant but sold the Maggies!
