McIntosh and Autoformers. . .?


What is an Autoformer, and what kind of difference will it make to the sound? I heard some B&W 803's the other day with the McIntosh 402, and it sounded absolutely unreal! I was so impressed, I am thinking of dumping my current SET gear, and going with McIntosh and B&W's.

A freidn tells me that I only want the new McIntosh stuff with the Autoformers. I don't know why. Will the 202 have similar sonic characteristics to the 402? What about the 6900?

Thanks!

I like the autoformer. I've owned some nice Krell and Levinson, but after listening to the Mac I hear a slight ocillation in those, mostly on strings and voices. I never noticed it before and it is slight. I think it is due to the AF, as it presents a steady load to the output stage. With a direct coupled amp, as the impedance of you speaker changes with frequency responce, and music is all over the place, the output stage will dish out more or less current so it's flucuating alot. Certainly the Krells and Lev's are up to it but it's still flucuating, and they may have their strengths too. Take all the advice you can get, but make sure you "buy" what sounds good to you or else you are a loser.
