Why the hate for mcintosh amps?

I have read that having a McIntosh repaired can be a crap shoot. Sometimes it will come back with shoddy work being done depending on who benched it. But to be fair that could happen with other brands. I also think that when a brand is purchased by a larger conglomerate profit is the goal not the sound quality, I also like to speak with ownership when I have a problem that is why I have PS Audio and Pass Labs gear. When it comes to service after the purchase I would challenge anyone to name two other companies in the industry that do a better job.

McIntosh must be doing something right. I reckon they sell more high end audio equipment than any other manufacturer out there. I collect wine as another hobby - this reminds me of the wine boards where the “cognoscenti” will trash a successful wine producer for nothing more than the wine being successful and more mass produced than some obscure label. Buy what you like and like what you buy!

Dumb question, there isn't an amp mfg out there that doesn't admire McIntosh's longevity, contributions to the industry and annual unit sales, people like what they have and if it isn't McIntosh would you expect them to say how good they are? 

How "veiled" is McIntosh compared to others? 

Way back in my College Park days, to be among the gods of stereo, McIntosh driving 901 Bose was Nirvana....so many thought.  The people I met then, are much the same as today: to really be impressed, the volume must be high with Mc., and especially with Bose.  By the late 70s, lots of reading, listening and experiencing Conrad Johnson, Audio Research, AR, Quad, even Dynaco, among others,  began a journey that continues.
