MAC Autoformers?


Someone is selling a MAC MA6500 Integrated claiming its superiority over the Ma6600 due to the fact that "it does not have the degrading autoformer design found in the MA6600". That is the first time I've heard a claim that the autoformer was a hindrance to better performance; I thought quite the opposite. What do you MAC Maves think?

For us non Mac enthusiasts the autoformer has always been proof positive that Mac had no idea how to design a transistor amp, perhaps they are coming to their senses at last.
I'm not even sure what the autoformer does. It seems like an effort to provide the same level of power no matter what the impedance load of the speaker is - which in theory sounds like a good thing. But I don't understand much of this. I did not know there was controversy regarding autoformers - so I wait to be enlightened in the issue here.
