thoughts on the Music Fidelity CD-Pre at 1,300

I am considering the Music Fidelity Cd-Pre at 1,300 (new). Is this a good preamp and cd player? Is there better for the money (used is ok)? I have a pair of Martin Logan SL3 and a Aragon 3002 on the way. Suggestions? I would like to have a tuner in the preamp .... is the B&K Pt3 a good piece?

on another note... why do the 1,000 cd players sound better than the 200 dollar cd players? what is better about them sound wise? how much better sound wise are they?
why do pre amps sound better than an a AV rcvr used as a preamp? how much better do they sound. I know the best way is to hear it, but that option not available at this time.

thanks
