Richmon, I'm also surprised that a $3000 player didn't cream (as you say) a $630 set up.
Perhaps the Marantz/X10 sound better to you is because it is just synergistic with your present set up (speakers, amp and preamp), not because it is intrinsically better.
With different equipment downstream of a "$3000 CDP" you might find you would have a more natural, musical, resolving, etc sound. You would no longer need the X10 to round off the edges of the CDP to make CD's more listenable.
IMHO the more add on's (buffers, cables,etc) the less resolution you will get and the greater the potential for adding distortion and other undesirable gremlins to the signal. Just food for thought!
