Since you are using only one converter box, you might want to consider making the ADA8200 your clock master. This will likely give you the lowest possible clock jitter. Remember that where timing jitter really matters is at the converter itself, because that's where jitter can actually affect the sound. There is almost ALWAYS an increase in jitter when slaving to an external clock. This is because of how a PLL works. If you use the internal clock of the converter box, it isn't being made less stable by having to follow an external clock.
So, if you are using only one converter box, and you want the most stable clocking for the converters, set the converter box to its internal clock and have the interface on your computer being clocked from that. Optical will be fine for this.
Cary -- interesting. I did not know this.
Why wouldn't any jitter affect the sound equally wherever it occurs (notwithstanding the degree of jitter actually being worse in one place than the other)? The "tainting" of the signal is happening in the digital domain in either case; the conversion is a separate process from the "jitter process," isn't it?
