In reply to:
Well, I am currently running RCA from the DVD to the NAD. I am certainly no expert at all with these matters, but I was under the impression that running a coaxial audio connection would improve the sound somehow.
Mike, I am confused... It sounds like both "RCA" and "coaxial" cables in your sentences above refer to "coaxial (shielded) cables terminated with RCA plugs" after all...
Anyway, digital audio transmission will either work perfectly or do not work at all (intermittent sound drops, obvious noise/distortions...). There is no such a thing as "subtle improvements" in sound quality here.
