Most of their amps do have the autoformers, but there are exceptions. One was the MC2002 (200 wpc solid-state) and the one I own, the MC7200 (also 200 wpc). And as stated before, their multi-channel amps don't have them.
Having owned many Mac amps, with the exception of the newest models, I personally don't care for the autoformers. That's just my opinion. I also find it curious that other high-end manufacturers don't use them. It's a carry-over from the old tube days. It's been a good selling feature for Mac. I'm hopeing my MC7200 hangs in for many more years!
mc275 has autoformers and is tube. I think it may be one of the original autoformer designs by Mcintosh.
Aside from bandwidth limitations that should not affect sound frequencies, there are lots of positive qualities that make an amplifier stable and reliable.
