Nice review! A couple points to add (for those of us with an audiophile slant

)...
-The BDP-83 actually uses
different DAC's for two-channel
Cirrus CS4398 vs. multi-channel
Cirrus CS4382A analog output. The two-channel DAC is the higher quality chip, and compares favorably to my Benchmark DAC-1 for Redbook CD playback (with the Benchmark yielding a tad cleaner bass and overall detail).
-Oppo also (smartly, as in the 980H model) includes a "pure audio" option (via the remote), which turns off all extraneous video circuitry to minimize noise during pure stereo playback.
IMHO, this
Universal player truly meets the needs for both the high-end video and audio setups. Given Oppo's reputation of stellar customer support, I'm sure they will continue addressing the few glitches, and optimizing performance further, with subsequent firmware releases.
