Does the length of the coaxial cable make a difference in sound quality for a home theater system?

Question

We just purchased the Onkyo HT-SP904 home theater system at Circuit City and discovered that we need coaxial cables because the receiver requires a separate audio connection. We have access to 12' length digital coaxial cables (from a friend who will give them to us) but really only need 4' length ones. My question is: will this make enough of a difference in sound quality to warrant purchasing new 4' coaxial cables?

Answer 1

Since it is digital, no decrease in sound quality should be heard. However, the length of the cable may render the source unable to transmit the data that far, but it should, since HDMI is good up until 15 feet, but after that, it doesn't work well. Coax is a much less complicated signal and cable, so 12 feet should be fine. Actually digital coax is just a standard RCA cable, so if you have any RCA cables (like red and white stereo audio, or composite video, the red, white, and yellow) lying around, that will work just as well for digital coax.

Answer 2

The 12 ft cable will be fine. It will sound identical to a 4 ft or 25 ft cable because the signals are digital, not analog.

If you decide to reduce the clutter - get a 4 ft Video cable. I like the ARPro2 series from BestBuy, but MegaCable from Radio Shack is decent.

Answer 3

not in coaxial cable it doesnt make a difference
