As many here have chimed in on the new Mcs posted here I may as well submit my two cents - FWIW.
I look upon new McIntosh much as I look upon new cars: Interesting, sometimes even exciting but never something that will ever wind up in my driveway or audio rack. I have absolutely nothing against, nor is should it be construed as anything negative toward either. I simply enjoy the hunt for McIntosh from the era that first endeared me to the brand, in the best condition I can find.
I also got to enjoy a few nice pieces from the earlier tube era as well. It also makes good sense economically since I've never had a problem coming out of ownership with little to no downside, and even managed to turn a modest profit in more than a few cases. This of course would be practically impossible with new cars or new equipment.
So what do I think specifically of the C8 & MC830? I'm sure they're fine and perform as would be expected of anything bearing the proud McIntosh escutcheon.
Is the C8 missing features I consider absolutely necessary for a first class hi fi system? Definitely.
Is it designed for convenient operation and placement? Not in my book.
Styling? Not my preference.
Will it appeal to current buyers of high-end hi fi looking for something slightly unique? Very likely - and my sincere hope is that McIntosh will do well with them, personal preferences aside.
