How much cable length is too much?

I just rearranged my home office and the Mac (running iTunes) is now about as far away from the receiver/amp as it can be. It's looking like the only way to connect the Mac to my receiver is to run an audio cable up the wall, through the attic, across the room, back down the opposite wall, and into the audio system ...

... to the tune of about 40 to 50 feet of cable distance.

I think I had a length like this a while back and I vaguely remember getting some hiss, although I don't know for a fact if that was the cable length causing that or something else.

Right now I've got a spool of 18 gauge speaker wire, would that do the job?

I guess it's two questions.

1) How much length is too much to connect a computer to a receiver?

2) What gauge wire is required for such a length?

Airport is a wifi station. Data is transmitted digitally and therefore does not influence sound quality.

but both the suggested solutions allow lossless, so no quality loss.

Assuming the OP likes the existing (via a Mac) interface, and doesn't want to replace their (probably) non-Airport receiver, I'd try a long, reasonably well screened cable. Beware of earth loops, different phases of mains wiring at the two outlets, and running the wire close to (especially in parallel with) other cables (it can pick up interference this way). If the computer has a digital output, and the receiver has a digital input, use that if it's SPDIF (coaxial) - I have no experience of using TOSlink (optical) over a long distance.

The choice of wire matters, but it doesn't need to be expensive. I ran SPDIF over 50m (164ft) of the worse coaxial cable imaginable, and it worked fine except when I switched the florescent lights on.

Hope this helps.

Cheers,
David.

Yes but you can be sure your crystal-clear artifacts will not suffer any degradation in transit. emot-pseudo.gif
