The Law of Diminishing Digital Returns

When is the sound good enough? Is that $2500 CDP $1500 better sounding than the $1000 player? I have read posts on members favorite CDP'S - i.e., Ayre, Opus, Sony, Rega, Arcam, Naim, Musical Fidelity, and countless others. I guess my question is: When you get to a certain price point (I am guessing it is in the $1000 - $1500 range) are players worth the additional $1000's in some cases for the 5% improvement in sound quality? There has to be a player out there that is really close to those $4k to $5k CDP's that is a pleasure to listen to (or even a Giant Kiler) for around $1000. Am I the only one who feels this way? Let's keep modded players out of this please. I am looking for your thought on players right out of the box that wowed you!
