OK, this is kind of a rookie question. I've got an SACD player hooked up to my reciever, which requires 6 RCA cables, one for each channel. My friend gave me an extra set of Accoustic Research audio/video cables, and I bought an extra matching set to give me a total of six cables, 4 audio, 2 video. Are the composite video cables OK for carrying an audio signal? From what I can tell, they are just rated higher. (75 ohms?) I'm using the video cables for the center and sub, and they sound fine to me. I just wanted some opinions on this, and whether you think I should quit being a cheap-ass and go buy another set of audio cables, or just stay with what I've got. It sounds great now, but I wonder if I'm not getting all I can out of it.
