This is what JA of Stereophile says
“Finally, the Weiss DAC202 offers the best rejection of datastream jitter I have encountered. I have shown the spectrum of the processor's output when fed FireWire data representing 16- and 24-bit versions of the J-Test signal (fig.12). The AES/EBU and TosLink spectra are identical. With 16-bit data (cyan and magenta traces), the harmonics of the low-frequency, LSB-level squarewave were at the residual level, and were not accentuated or modified by the DAC202. With 24-bit data (blue, red), all that is visible is the central spike of the Fs/4 tone, this sharply reproduced, and with very little spectral spreading at its base. The jitter was too low for the Miller Analyzer to measure. Again: Wow!

Daniel Weiss prefers FireWire as the communications protocol is less likely to induce LIM due to the way it streams data.
I think you have nothing to worry about but if you find buying more gear or extra cables will alleviate your fears then why not....
