"Specs? I don't know what the hell they are...let me look in the owner's manual. [...] We don't do much with specs, because specs have very little to do with how the thing sounds." (Ayre's Charlie Hansen quoted by Stereophile.)
Nap. 
While I agree that typical measurements can not totally characterise a components "sound" it is still a rather moronic comment imo as there are many who don't have local dealers, stocking $18K preamps

... and therefore no way to convienently demo equipment...therefore specs are often a way to weed out BS designs from the real performers. If a manufacturer refuses to list specs they either are incapable or they're hiding something imo...both situations give me pause.
It's like people who buy amps guided mainly by watts rating...without knowing current output capabilities and other little "specs" that have no direct correlation to "sound"

Peak current and raw weight of an amplifier are "usually" important indicators as to what power an amp is truely capable of regardless of "sound". If you don't have the power to generate the spls you desire I can tell you a underpowered/overworked amp is going to sound like dookey

...regardless of any marketing drool-excuses put forth by the infidels
