I've finally reached a place in life where I can afford nicer stuff. Having been one who appreciates quality, I've had to make the best out of lesser things along the way. I've lived a great many years with Champaign tastes and a beer budget.
For years, my home stereo consisted of a pair of Heathkit A-9b amplifiers that I had rebuilt salvaging only the transformers and the chassis. These have given me many years of delightful music at about 23 watts per channel.
My entry into high end equipment was recent, and as another writer suggested above, my knowledge of high end equipment was, and still is, limited. My choice was the Mcintosh MC275 Mk VI and the Macintosh C2600 tube preamp.
What motivated me was several things. First, I have a fascination with older technology that works. The MC275 has been in production for over half a century.
Second, sound quality. Listening to these in the store, I could pick out shortcomings in my existing equipment, which is hard to do; those old Heathkits have some nice iron on the output side and conservatively used their components. It wasn't just the difference in power, the MC275 had a better transparency than the old Heathkits. That was a rare experience for me as most systems I listened to were disappointing compared to those Heathkit amps.
Third, build quality. As others have stated, Mcintosh has a great reputation for quality construction and using quality components.
Fourth, resale value. One would be hard pressed to find another brand where the difference in the cost of a new unit and the cost of a used unit is often less than 20%. I could drop 10k and get 8k back off e-bay 5 years later if I want to sell. If I dropped dead tomorrow, my wife could sell the equipment for enough to bury my fat rear end.
Appearance, while I love the mirror finish chassis on the MC275, the layout is a bit awkward for me. The connections are on the same side as the switches, and either that panel or the tubes will be on the side. So, appearance didn't sell me on the MC275.
Appearance on the C2600 is beautiful with the glass front panel. Not a deal maker or breaker for me, but definitely a plus.
Connectivity on the c2600 is also very nice and so is the remote.
Anyway, I'm very satisfied with this equipment.
