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?

"A simple test is to put a well known Auto Former that’s used on OLT’s to make them "sort of work" into speakers they can't drive without them, on the rear end of good solid state amp (say a Pass Labs) and watch it transform into rubbish."

georgehifi,
Did you perform this test?

Yes I had a customer trade a pair in, he tried them on his Lamm 1.1’s and didn’t like them, I put them on my very good solid state amps with my ML ESL speakers to see what they did, and it made them sound like old an Williamson tube amp soft polite and rounded. As I said the same years ago in Audiogon.

Mac did build good amps, they were the 275's, should never have gone to ss with transformers.

my guess is of course not......geez.....
Really!!!


Honestly, I think the big thing is taste. 

From the perspective of creating an ideal voltage source, the autotransformer is garbage, but if that tickles your ears, and it is your money, then that's what you should get. 

That simple. 

Best,
