I definitely agree with you on the pyschology / science argument Clint - although I'm sure most of the experienced HTFORUM members here could tell the difference between a set of Paradigm vs Fluance. I mean, I easily noted an audible difference (in clarity and depth - not the tonal differences) when I switched from Polk to Paradigm.
Although, I think the real psychological part kicks in @ the expensive, exotic end - where you get maybe a 5-10% increase in performance for a 2-3x increase in price over the product before it.

Oh yeah, don't forget the interconnects/cables!
