When I first saw pictures of McIntosh gear I honestly thought it was a spoof mocked up in Photoshop. I refuse to believe anyone could actually manufacture anything so despicably fugly. Nowadays I would just dismiss it as one the more egregious hallucinations of an AI-bot. However, there seem to be many people who claim they do actually exist but, having never actually seem one in person, I'm still not entirely convinced. Please tell me they're just some kind of edgy audiophile satire ...
They exist. There are a few Mac pieces here.
I won't quibble with their electronics, but Mac's hifi components' aesthetics, by and large, strike me as clumsy and inelegant -- although some of their tuners (
viz. the MR-71 shown earlier) are elegantly attractive. More recent Mac components have gotten gauchely gaudy.

Even the above-mentioned MC275 over the years has sprouted LED 'status indicator' lights glowing up through the small-signal tubes.
The old tuner-preamps aren't bad, but they're not
inspiring aesthetically, either. They're
pretty good products, though, overall.
There
is an MR-67 here, in full disclosure -- it is a very good FM stereo tuner, as well.

Cosmetically, quite similar to the aforementioned MR-71.
Here's a rear view (
hubba-hubba! -- you know
, some of us like that sort of thing

) of the MR-67.
It's not obvious from the photo, but it
is chock-full of vacuum tubes, but many are shielded (as befits a VHF radio

and, if memory serves, the front end uses Nuvistors -- interesting little metal and ceramic vacuum tubes from very late in the tube development epoch that... well...
don't glow. The were excellent for high frequency use, and at the time (late 1950s-early '60s) when they were developed, high frequency transistors were difficult/expensive to manufacture -- so vacuum tubes hung on for a few more years in radios and TVs in their 'front ends' until good, reliable, and cost-effective FETs became commonplace.
Nuvistor on the far left (of course).
