I've had McIntosh gear for 35 years. I'll always remember getting panned for owning MAC gear at a particular audio store and would get the typical sales pitch that McIntosh was not really audiophile gear (and "let me show you this unit from such and such manufacture that is tons better!"). That was until that same store became a McIntosh dealer, then it was the best stuff in the world.
And, in my local area many years ago, some of the bars/clubs would use massive McIntosh amps to power the bar sound system. In a couple clubs, the amps were all beat to death from bartenders / staff putting stuff on them since they sat out in the open. Meters would work, but bulbs were usually all burned out...those amps looked horrendous cosmetically...but would crank night after night after night.
@carlso63 - Agreed on the exclusivity aspect that you bring up. McIntosh is pretty readily available and that doesn't sit well with people that want exclusivity. So, it gets easily passed up as non-audiophile gear.
