Care to provide data on why you don't think a little test with amps similar to the one above would not yeild the same results with people's perception of what they are hearing? There's a point in most markets where prestige pricing takes over from common sense and it prohibits people from objectively viewing/listening to something. It's funny to me how people with the big expensive $20,000 setups and components will argue all day that their stuff justifies the price.
I don't want math or scientific research on why 10K is better then $600, I want to hear peoples opinion without them being biased on what the source is. I would venture to guess that it would be very hard for people to distinguish them, all other things being equal in the setups.
