Hm.
how does graduation, or fornication, affect perception of sound?
ever since i constructed the 200 L, 12" full-range speakers, i can hear details i could never hear before. MP3? screw that, i can tell if a cd has been properly recorded. metal? pointless. pop? even more so. it sounds clear and perfect, but it is like artificial food flavoring. Acoustic jazz (no electric guitar, eg)? yes. full orchestra? sweet sweet fulfillment.
I had sex 10 years ago for the first time and graduated high school 15 years ago, fwiw.
in relation to this topic, i am thinking of getting a turntable, see if the filters on DACs' outputs have any effect on stereo imaging (and for the first time in my life, excepting binaural audio which in itself is a *revelation*, i understood what it means, because you have to place your head in centimeter-exact position).
