If Mc amp buyers didn't
want autoformers, they must have been stupid to buy
McIntosh, unless of course they bought the autoformerless
ones.

I never said that Mc amp buyers were necessarily the sharpest knives in the
drawer.

Few did, which is why Mc went back to autoformers.

Then why does this current product lack them?

Proof of absence of autoformers on page 18 of the user manual.

The MA6300 is probably an integrated amp, many of which have had no
autoformers. Most of Mac's power amps have had them but some do not. I
am not an engineer and I do not work for Mc Intosh and do not represent
them. Some Mc amps do not have autoformers, and I said that a long time
ago. I also said I do not prefer autoformers, do not endorse
autoformers and do not care what Mc builds now, especially. My interest
in Mc amps today, is limited to building replicas of certain of their
vintage tube amplifiers using new reasonably priced transformers when
and if someone makes them available. I do not state such amplifiers are
the best possible amplifiers, only that they serve my purposes to my
satisfaction, and the opinions of Trevor or Arny are quite beyond my
consideration in that matter.
