Everyone (except knghifi and danmyers) is assuming that the problem with Oppo's BDP83 is the DAC but I actually talked to Dan Modwright and he thinks the chip sets for both video and audio conversion are top notch. The achilles heel as Danmyers put it is the analog output stage. MW, among other mod outfits, currently has a solid state modification for both 2-ch and 5-ch analog output stages. Modwright is out with the solid state mod first for the BDP83 but has plans for a tube modification for the analog output stage which I am waiting for before taking the plunge. I actually think that the Oppo's CD, SACD, and DVD-A/V playback is respectable (and I am comparing that to my ARC Ref CD7, at least on red book CD playback, which clearly outperforms the Oppo unit by a country mile and it had better do so at the price differential).Yes SACD sounds better on the BDP83 than CD but I think that is a function of the higher resolution format. By beefing up the analog output stage, one ought to convert what is a very decent universal player into an audiophile quality player. Would love to hear knghifi and danmyers' experience with the MW mods.
