I thought I knew the answer, but alas, my brain isn't cooperating.

I finally ordered a new receiver today to replace my old Technics Dolby Surround(circa 1988!) with a Denon AVR-883. I'm taking inventory of the cables I have, and once I have the answer to the following question, then I can buy my missing cables:

If I have a source that has a digital audio output, do I even need to connect the analog audio outputs to the receiver?

For example, LD to receiver? DVD to receiver? SAT box to receiver?

Here are model numbers, if that helps.

I really would like to eliminate any redundant cables (and keep a few bucks) if possible.

And I am working on my wiring diagram so it can be double checked; I may post it later if someone wants to "grade" it.

Thanks for everyone's help.

Generally no, you don’t have to connect the analog audio outputs for digital equipment. There are a few caveats, however:
  • If you ever intend to record any of these sources to a VCR or other recorder with analog-only inputs, you will get no audio to it if you’re using only digital connections.
  • As you may know, laser disc player is different from a DVD player or satellite receiver. Its output is an RF signal that has to be demodulated to Dolby Digital. Few receivers have an on-board demodulator.
