I'm using McIntosh 601's and a c47 driving my Salon 2's. My listening room is somewhat on the small size, but fairly well treated. For me, the room treatment was the key to a really good sound stage, deep and wide. The speakers pretty much disappear. The sound is on the warm side. That said, all of the detail is present, but the warmth may take away some of the perceived detail in the upper mid range. It's just the McIntosh sound, but I have always preferred it. I will say, you can run the Salons for long periods of time and the amps stay relatively cool. I had my last McIntosh amp (mc2500) for 30 years and never had to have serviced. All of the above mentioned amps are really good. Just different sound
characteristics.
