Keith, I REALLY think you hit the nail on the head with this one.
Saying that they prefer this or that or they know someone that prefers something or something else is as bad as "snake-oil" to me. I personally only care about what I think when I hear something and if it works for me. I could care less what anyone else thinks about comparisons.
Then add in that whatever someone else likes in a completely different room, different system, different ears/brain etc......geezzzzz.
True. But so many of us know it and forget it.
