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?

Mac's autoformers kills the amps transparency characteristics.
Also some used to refer to them as having poor transient response(the autoformer). That was a big edge companies like Accuphase had over Mac transistor amps years back,plus other companies now.
