McIntosh Amp Ratings

Does the Autoformer design of Mc amps allow them to rate their amps at higher watts than competative designs? They are one of the few using this design so I would think if it really was great, others would copy.

Is a 250 watt Mc actually comparable to a 125 watt other amp (which would double to 250 @ 4ohm) since most amps are rated at 8ohms?

Don't get me wrong. I own some Mc gear and love it but have wondered if they have clung to this for the spec wars.

The Autoformer doubles down and halves up depending on what terminals you run the speakers off.

I explained this in another thread for those who are interested...

Aball-

You're spot on about the McIntosh Autoformer...it can deliver more power at lower impedances but it, like all other amplifiers, is limited. The Mac is probably more conservative as part of their design intent is to minimize heat generated to prolong life.

also, Autoformers kill damping factor, which probably explains why traditional output designs that offer better control of the woofers are prefered by some.
