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?

Hi all, After reading this discussion I just thought I'd mention that I've noticed on the used market McIntosh amps that have autoformers seem to go for more money than the ones without. I've seen some Mac amps from the 70's go for more money that ones with out autoformer that were made in the 80's and 90's. Also I have a Mac MC2105 and I think it sounds much better than the Adcom or the Belles amps that I had prior to it. And go figure, the Mac is close to 40 years old and still works like a charm.

My System:

McIntosh MC2105 Amp
McIntosh C504 Preamp
Sansui TU666 Tuner
California Audio Labs Alfa DAC
California Audio Labs Delta Transport
Micro Seiki DDX 1000 Turntable w/ Sumiko Premier MMT tonearm/Linn Asak MC cart.
Musical Fidelity X-LPS phono preamplifier
Vandersteen 2CE Speakers
