Why do no audio enthusiasts use McIntosh?

Not to say there aren't a lot of people who by McIntosh equipment for the blue meters/snob appeal. There are .But there are many who love the sound of the music played through McIntosh equipment. I have a pair of MC 60s. The tone and organic quality of the music I listen to is the reason I like the MC 60s. 
I think the reason many hold on to their vintage McIntosh is they don't get tired of listening to it. What's wrong with that? 

Listening? Come on man...No…it's the blue meters. If more amps had blue meters the world would be a better place.

On third set of amp(s) and preamp combo in 19 years. Only once anything needed service and it was done quickly.  In 25 years there will be a network and the parts needed for service.   Love em or hate em, the newer gen amps and preamps are neutral enough if that if it's not exactly your flavor it can be changed with ancillary components and cabling. 

For many years I had one NAD setup after another, eventually their "Masters Series" components, really enjoyed their sound.  Many years ago I worked at some high end dealers who sold McIntosh, but never "lusted" over the equipment.

About a year ago I decided to see if I could find some speakers I liked better than the monitors I was using and as I auditioned one pair after another I was struck by how easy it was to listen to speakers powered by the McIntosh C50 pre-amp and MC452 power amp.  To me they just didn't seem to have their "own sound", and had not a trace of edginess (which was a good thing, having finally selected a pair of speakers with quite "capable" tweeters).

I know that, in some circles, McIntosh is a dirty word.  The great thing about our hobby is how there are so many products to enjoy.  I just happen to enjoy my solid state equipment from Binghamton.

Swl love Macs and it has nothing to do with the blue meters.
