Thanks.
I ask because I've flirting with a McIntosh integrated for a second system. That way I've got two different sounds to play with. So, I went to a local Mc. dealer to audition a MA6600 (SS w/autoformers) 200 watts/Ch. ($6000). It was hooked up a pair of Sonus Faber, don't remember the model but they were about $5000 a pair and an unknown CD source. I had them put in a classical CD and I was astonished! Astonished at how bad that set-up sounded. I expected the sound to be a little warm/liquid and maybe not as transparent as my Bryston system. I was expecting the fabled Mc. sound , what ever that is. I couldn't believe the sound, it was boxey, muddy, no detail in the highs and no life to the sound. I looked over at the dealer and he seemed to be happy with the sound.
Don't know why I even posted this other than the fact I was so surprised and disappointed with the sound. I can't help but think there was something wrong somewhere in that set-up If what i heard was the Mc, sound, I'm cured from going down that road again. My little B-60 and Studio 20's sound better than what I heard.
Thanks for the info on the autoformers.
