Why the hate for mcintosh amps?

If, to me, there is no discernible difference in sound between components (preamp, amp, speaker, etc.) I will always choose the one with better visual appearance and craftsmanship. I will even pay more for the better looking component and better craftsmanship all other parameters being equal. If that means I get pretty blue meters in the purchase, so be it. 

  "Imo, you are paying for the pretty blue meters....😄"

You're so original audioguy85. I never heard that one before.

That’s what I like about McIntosh, not only they look good with the blue meter, but they also sound incredible.

‘No discernible diff between components’?

A high quality revealing system will reveal differences. Try eliminating reverbs in room, makes it easier to hear component quality changes.  
Not rocket science.

Not what I meant by my comment at all.
