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?

I am 72 and tinnitus has ruined my critical listening capacity, but my first job in HiFi was at a McIntosh dealer. At age 21, my ears were fine, and although I thought I knew a thing or two about audio, I was really just beginning to learn. Our demo system was a C28/MC2105 combo. We demoed from a Pioneer 10” reel to reel playing tracks recorded from a Dual 1229 with an Audio Technica AT15S. Our favorite speakers were ESS AMT-1 Towers. My reading had led me to conclude a Crown DC300 and IC150 should outperform the Mac gear, but listening to each in our sound room proved otherwise. This was all played through 12 gauge zip cord of course…Noel Lee hadn’t happened yet. But those auto formers sure didn’t hurt the sound…

I like more open, unveiled sound.  I've heard MAC many times.  I just can't warm up.  Their amps have plenty of power and are cool looking.  Product loyalty is their big deal.

@daledeee1 Thanks for imposing on us your personal view of why people love their McIntosh gear. It really adds value to the conversation and OP’s original question 

You can call me shat you want but I have McIntosh from the preamp to the speakers. C2700, MC611, XR100 and they sound superb. The only thing not McIntosh is my turntable which is VPI.

I for one have a hard time taking audio advice from anyone who can’t even spell McIntosh correctly in their shouty posts…

That said, call me a fanboy, a dummy, a fool. I don’t care. I love my McIntosh C12000 pre, MC611 monos and MCD12000 transport/DAC. Puts a smile on my face every single time.
