I was considering starting a thread very similar to this one, you beat me to it.
I'm of the opinion that many 'philes go for what sounds good on their system and happens to be in their wheelhouse. Some of you remember the days when an audio demonstration included sound effects tracks...jet planes, trains and such.
It also appears to be readily apparent that many contributors to this forum are music lovers as opposed to equipment addicts. I love all my gear, but not to the point that I discount music because it doesn't stand up to what sounds the best on my system.
I do not listen to music that I dislike, I only listen to music I really like. There is a life time worth of listening in that category.
As an aside, if I start to think that my rig is not performing well all I do is put a 78 on my 1917 Victrola. And then listen to the same music on the big rig. Brain foolery works every time.
