This thread has lots of great info on patch-cable length interconnects, but what about longer ones? I'm wiring up a second zone that's about 50 cable-feet away from the reciever. This, from what I've read pretty much requires the use of RG59 or RG6 coax.
For my purposes I'm planning on using:
Belden 9555 dual RG59/U - radioshack #910-1589
Centerpin RG59/U RCA connectors - radioshack #910-5482
I figure that since the belden cable will be good for audio since it uses bare copper braid for the shielding, and at 50 cents a foot for 2 RG59's the price was reasonable. I liked the centerpin connectors for two reasons: they don't require any specialty tools like strippers or crimpers; and it's a single connector to get all the way to RCA ends, instead of using F-to-RCA converters.
