My A/V receiver has 3 optical audio inputs, and 1 coax audio input. I will be connecting a DirecTV HD DVR and an upconverting DVD player. The DVD and the DVR both have optical and coax outputs.


From what I can find, there is no quality difference between optical and coax - so, would it matter which connection I use for each? Is it correct that the quality is the same between them?

For all practical purposes they are identical in function, quality, and limitations. You can use them interchangeably as seems best to you.

Theoritically speaking, the optical cable can be considered a better connection because the type of signal is not prone to the same types of noise (RF & EM) that can enter a coax cable. However, I've found that this rarely has any type of an impact, hence the theoretical proposal.
