you will get much more enjoyable sound out of CDs when you
A) address vibrations
B) address noise on AC / ground
lots of ways to do it---but you have to experiment. inner tubes under a maple butchers block for vibration is a nice cheap tweak, and i'm still playing with products on treating AC (the Acoustic Revive ground conditioner is a very nice product, and their power conditioner is a great product, and i'm about to plug in Audio Magic's Pulse Gen).
i can listen to CDs all day with no fatigue. having an EMM CDSA helps ;-)
