hi snofun3:
what is your point ?
on a personal level, one can prefer the sound of component a as opposed to component b. perhaps, using certain sources someone can hear a difference, with others a difference is not detectable.
this is not a test. there is nothing to prove. it's not that testing for differences is not useful, it may not be relevant to equipment purchases.
if i can borrow an amplifier and live with it for 30 days, i either like the sound of the stereo sysytem with the amp or i don't.
