While the sonic quality of a complex audio product is based on many factors, one that gets a lot of attention as being pivotal is the DAC chips. Both the XMC-1 and the SSP-800 use TI (Burr Brown) chips. The similarity ends there.
DSD 1793, ..
S/N 113 dB, THD+N 0.001%, ..
$2.36 (small quantity prices for comparison only)
SSP-800: PCM 1792A, S/N 127 dB, THD+N 0.0004%, $7.08 (used for front channels)
SSP-800: PCM 1796, ..
S/N 123 dB, THD+N 0.0005%, $2.70 (used for surround channels)
And there's more to it than DAC chips. A couple other design features of the SSP-800:
1) Up to 10 layer PCBs which will provide better isolation between power and ground planes and will reduce potentially harmful interference thus improving signal integrity.
2) Opto-couplers and low voltage differential signal (LVDS) pathways thoroughly isolate audio circuits, video circuits, and control circuits.
Well, you get the idea...
