Seeking Honest Opinions: Your Experience with McIntosh Audio Gear

My Mac experience is that the tube stuff is a bit bottom heavy, the mids are good and the highs are a bit muted.  If you buy a brighter speaker like the B&W 800 series, tube Macs sound great. 
I never had a problem with their equipment, so I can’t speak to their service department.

They definitely have their own sound and will not work well with any speakers.

As an aside, they keep their value better than most High End equipment.

All the best.

OP..I have owned 3 McIntosh components

1. Sound Quality: How would you describe the sound signature of McIntosh gear? Natural, musical sound. Neither warm nor harsh to me.
2. Build Quality and Design: McIntosh is renowned for its craftsmanship. Has their build quality lived up to your expectations? NO..I purchased a lemon C-220 preamp that was not manfactured carefully. I sold it within the first year. No "firmware" updates for my stereo, thank you.
3. Value for Money: Considering the premium investment McIntosh demands, do you believe the performance and satisfaction derived justify the price? Too subjective a question ..every listener has a different definition of value.
4. Customer Service and Support: Have you had any experiences dealing with McIntosh’s customer service? If so, how would you rate their support? YES..I contacted support, helpful folks. My problem included the fact that after I took my C-220 in to a authorized service center MAC dropped the dealer off the authorized service center list while it was in for service. Ya can’t make that up.....
5. Overall Experience: Would you recommend McIntosh to fellow audio enthusiasts? Why or why not? IMO the recent (last 20 years) McIntosh gear is not made like it used to be. I would consider buying the 60s and 70s McIntosh gear if an expert MAC repair/restore tech is able to refurbish/maintain the gear. Better yet, buy PrimaLuna gear and as much as I like to buy US made gear, just enjoy a reliable experience with new equipment. I also recommend Schiit for great USA made stuff.

Couple of fun facts before this falls apart: 

1. Still made in the USA. You can make an appointment to tour the factory in Binghamton, NY. Not sure, but I think tubes are still Russian.

2. They own Sonus Faber & Sumiko

3. They are owned by Highlander Partners, a private equity co out of Dallas, who owns a bunch of companies in many diversified product categories. They buy and sell companies....for profit

4. They did a deal with Jeep to put car audio systems in some models. Jeep forums seem to report they sound "pretty good" 

Have had the same (purchased used in the mid 80s) power amplifier for 40 years now. It has been mated to many different tube and solid state phono stages and preamps leading to improvement in sound quality over time. I listen to it almost every day. It has a strong yet warm sound quality and has never been serviced or repaired since the original purchase. I think this speaks volumes about the build quality and excellence of what they manufacture and continue to manufacture. As far as the value proposition is concerned, I think it is worth about 8 to 10 times more than what I paid for it when purchased used.

OP is asking us for opinions about a brand, not a product. This is a marketing issue, not an audio issue. Yes, he asks about "sound quality", but from my experience, every component, McIntosh included, sounds different from other products of the same brand and sounds different in combination with other components. The sound of my MC2775VI, for example, is highly dependent on the preamplifier with which it is paired, not to mention the speaker hooked up to it. The other questions are, as I said, marketing questions, and are best answererd by the fact that Mac has been in business continously for 75 years.
