I just bought the Grado 60's in my search for budget audiophiledom... I hooked them up to my Sony 5 disc(about 10 years old) They sounded pretty good. Then I plugged then into my soundcard(SB Audigy LS)...which is 96hz/24 bit..Holy Crap..the diff. in sound was night and day. I never really knew what people were saying when they talked about good equipment revealing a bad recording. I put on Iron and Wine's E.N.D. I could hear the hiss come in when they layed his vocal over the guitar track...I could hardly go to bed...as I put on cd after cd...Awesome
