I have experience with the Pioneer BDP-09FD, one of the best "Audiophile" grade Blue-Ray players at this time.
This unit in conjunction with the Audio Research DAC7 sounds awesome, killer sound stage (deep, wide), great imaging and low noise floor.
I was using my PC->USB->DAC7 for about 3 weeks (.wave format) and yesterday popped in a CD into the 09FD with "Pure Audio" on, I was taken back. Now I need to fix up the USB audio from my PC because now I can't go back to it!
The Pioneer is a $2200 player though! If your processor does not do decoding of the HD formats, and your budget fits, get the Pioneer BDP-09FD.
