    Looking at this website:

    http://www.bus.ucf.edu/cwhite/theater/diycable.htm

    It looks like he is suggesting a 75 ohm cable Canare LV-77S for audio interconnects. Aren't audio cables 50 ohms? I think this would cause reflections or signal degradation.

    Thanks!

    Video cables are 75 ohms and audio cables can vary from 50 ohms to over 100 (I think 200 or 300 - forget). Jenving's site I put in the other thread has some good info too (under FAQ):

    75 ohm can be used for audio (actually any shielded cable can). The degradation is only a problem for video, when you try to lose 50 ohm instead of 75 ohm.
