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?

The only negative with Mac autoformers is in doubling the amplifier cost and weight.

"I have been looking at integrated amps and when researching the Mac I noticed the only ones without auotformers are the lowest rated at 100w. I wonder why that would be the case are they not needed in the low watt amps? I assume they could use them just as easy in a 100w integrated as a 200w integrated.

My guess is that this is strictly a marketing issue, by not including autoformers in low power amp they are offering entry level Mac products  for those who do not need big power, big weight and big price tag but still like to own a McIntosh.

I am going all out to prove my ignorance and ask a question on autoformers.

I suppose we all agree that one advantage of autoformers is to deliver the same amount of power regardless of variations in a given speaker impedance curve.

So here is the question: a speaker with huge variation in impedance curve will receive considerably more power where the impedance deeps way below its average curve, and if that speaker in fact receives more power at certain frequencies then those frequencies will be greatly highlighted, so there goes your flat response!

Yes? No?
