I've seen a lot of questions on this topic and I'm curious myself as I'm hoping to send audio from my PC to a receiver over a 75+ ft distance. I also thought it would be convenient to have this info in one place to help others in the future.
So, assuming quality cables are used, what maximum length might one reasonably expect cables to perform reliably?
1) Digital Audio Coax/RCA
2) Digital Audio Optical/TosLink
3) Analog Composite/RCA
4) USB
5) Speaker wire
6) Others?

A lot of it depends on the equipment being used and how strong the signal is to begin with. I've used 4 different satellite receivers to send a composite signal 40', 2 of them did it with very little or no loss, one of them was far to crappy to watch, the other one is OK, but not as good as it is over a short run. The best way to send signals a long distance is high quality RG6 cable. |

Were you using a high quality RG6 in your four examples? If so I'd think my 75' could pose problems. |

I used good quality RG6, not the best quality I've seen. I used the best cable I could find where I am. Audio is a far less complicated signal than video, the audio is fine, it's the video that isn't as good on some equipment. |

Related question, I would like to run a composite audio L/R from one receiver to another at 25' away. Is that too far for just the audio signal??
Newbie question, what is RG6?? |

Follow up question: Is signal quality effected at all by using a coupler (http://shrinkster.com/c0n) to join two shorter cables rather than using one long cable? (e.g., does one 80' coax/RCA cable = two 40' coax/RCA cables with an RCA coupler in the middle?)
Anonomous, I believe RG6 = similar but newer & better than RG59. |

While I'm at it I might as well also ask...
I'm not sure what to look for to determine cable quality. Would this qualify as a "quality" cable? http://shrinkster.com/c0s
Thanks for all your help!! |

Thanks for the link Berny. Well, I've done my reading and still don't have the answers. I certainly appreciate the desire to have posters do their homework and not ask questions that have easy to find answers. The answers to my questions don't seem so obvious though. Care to provide another clue, or maybe even an answer? |

RG59 and RG6 are the same 75 Ohm cables. Their difference lies in the gauge of the core. RG59 is usually 22 AWG vs RG6 which is 18 AWG.
RG6 - solid copper core
RG59 -solid or stranded/braide
RG6 -shielded with aluminum foil sheath as opposed
RG59 - braided copper wire shield

I think the DVI cables you were looking at are the same quality as the Recoton/generic cables. I don't think that they are well made at all. |
