I probably wouldn't use the oldest RCA cables laying around the house , but most of them should suffice for short runs. You could probably find a bundle in the neighborhood of $30-50 online give or take for basic multi-channel analog cables. More info-
The less expensive cable bundles are getting a little bit harder to find of late with HDMI being so much more common in the marketplace, but you should be able to find at least one set under $50. Most seem to hover around $100, which is way overpriced for shorter runs IMHO.
I have an older receiver(Denon AVR 589) with pass through HDMI
I am looking to optimize sound, by using the analog 5.1 cluster for lossless audio. I will likely be hooking a Blu-Ray Panny DMP BD85 analog out.....to the Denon analog in. I am having trouble finding anyone who definitively knows about this connection, or cables. Has anyone hooked up this connection; who knows anything about the RCA cables? Is there anything special about the RCA cables? Will any decent shielded RCA cable work? Is there a bundle cable, for this analog 5.1 hook up? I can't find anyone who has hooked it up this way; and have not come across any bundles yet. Any help thanks.
