I had a Bryston B100sst for 4 years and while I did enjoy it the Bryston has a ground loop problem (slight hum from speakers when source was selected and nothing playing). The Simaudio is very good if you like detail. To me that detail made me listen to my equipment and not the music - too analytical. The Naim is excellent (very musical) and would have bought one except I tried a tube integrated (Octave V70SE) and decided to go that route. Tu-be or not tu-be?! :)
