Is the "Burr-Brown" processor used by the Denon DVD players superior to most others ??? I have read a few positive comments on the Burr-Brown in this forum, but I am not sure what sets it apart (if anything). The audio D/A convertor in my Toshiba SD-4800 has the same specs (24 bit, 192 kHz) as the Burr-Brown, so should it be equally as good ? For that matter, does anyone know who the manufacturer is of the Toshiba audio D/A convertor ? I guess I am asking only because I am still thinking of buying a refurbished Denon 900 or 1600 player. I know the video processor (Faroudja) in the Denon should be better, and if the audio processor is also superior... I will probably go ahead and buy one of the Denon players.
