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?

I am pretty sure that MAC had or has a patent on the autoformer. It is expensive to manuf. I have had both.
I would not refrain from a MAC purchase because it did
or did not have them. They do put them in their more expensive equipment. The autoformer does keep that sweet MAC sound with all loads. MAC's without autoformers do not have problems with loads either.

I would not call them degrading.....I saw the ad the poster
was referring to.........it is an ad. I would not give the same opinion. I have sold a few amps that were more powerful to the ear and went back to MAC.

I think the 6300 is a sleeper......It does use THERMAL TRAK
which keeps it running cool all day.....it does not have
BASS/TREBLE controls but the pre-amp section is great.

It uses LED's instead of bulbs.......I thought the 6500
was quote unquote "louder" but the 6300 sounded better to me.

I like balanced inputs my self which the 6300 has.
With MAC people do not talk enough how important your source (cd player, dvd player, server etc.) is relative to your sound. Do not get me wrong, I know it is on all equipment, but you can REALLY hear the differences
on MAC stuff. Only as good as what you plug into it.

All three are good pieces of equipment. Never understood why the 6600 has such a bad rap.
