Trusting that “You Tube guy” with anything audio is the same as people trusting the Facebook persons with their Covid information. I LOVE every piece of McIntosh equipment I own. It sounds fantastic with my speakers in my 2 rooms and that is all that counts to me. Resale value is off the charts, in 2017 I bought a used McIntosh MA6600 Integrated, it looked brand new and it could have fooled me. That same amp is selling on eBay now for $6500. I paid $3200 for my mint piece with the 2 shipping cartons and a brand new remote. I liked the amp so much I bought 5 more Mac pieces within a 6 month period, all from Audio Classics
Say what you want but I know I can always get my money back and then some should I have a desire to sell any of the Mac, which I won’t. Doubtful there are many other brands that will hold their value as well as McIntosh where you can double what you paid for it. oldhvymec said it best though and I feel the same
