I have a great separate 2 channel system apart from my 5 channel HT. I would like to run the analog outs on my satellite receiver to my stereo pre-amp, to utilize the music channels available. When I'm done snaking them around, the length will probably run to 50 feet or so. Can a low-level signal be sent this far, and if so, do I need to use any special sort of cable? If this is feasible, where do I get lengths like this at reasonable cost? Thanks.
