Would McIntosh Auto Transformers affect speaker sound?

I have a question about McIntosh and its auto transformers. The auto transformers allow the wattage to be the same on all ohms. However, you have to pick which ohm to run on the amp to the speaker.

Since a speaker can be dynamic in ohms (dip between 8 ohms and 4 ohms typically), does this mean the McIntosh will not correctly match the dynamic range change? Would it cause the speaker not to give the same soundstage or holographic sound that a traditional amp would give?

About 6 years ago I was considering a Mac for my Maggie's so I called the factory and they recommended against using their autoformer amps with these speakers so I went with with Pass instead which was a terrific match.

I don’t care what the so called “ audio doctor” audiotroy says about McIntosh.  It is a great, well built, great sounding piece of American Engineering that has a higher resale value than most other brands.  It’s good enough for me and that is all that counts.

@johnto,

unfortunately, they really won’t work well with Maggie’s. The thing is, Without the auto transformers  the Mac magic is gone and it’s just another solid state amp.

Autoformers have very wide range of impedances handled at 4 ohm taps.
