Whee! A DBT argument and an "audiophile" argument all in one thread! Define audiophile. My definition: someone who can hear the difference (between good reproduced sound and great reproduced sound).
Notice: this has nothing to do with how much one spends, allows for whether or not one believes in burn-in, feng shui, olifactory therapy etc., and also allows for different levels of audiophiles. So for example, one might be able to hear the difference between a Bose clock radio and a Tivoli clock radio, or one might be able to tell the difference between directions on an interconnect.
Oh, and testees should never be seen -- maybe we should hang a curtain over them as well.
