How to make a audio over cat5 cable?

    I've heard about building an audio cable with a cat5 twisted-pair cable
    for long distance connection betweeb hifi output and speaker input.

    I have a PC (I know: it's not HiFi) in a room with a lineout output
    which I would connect to a couple of amplified speakers 10meters away.
    I guess the audio over cat5 cable is a solution in order to get a good
    signal (with low noise and signal loss) to the speakers. I am not an
    audio profi.

    Do you have any idea where can I look for specs about this technique? I
    googled around but I found just selling sites and no explainations on
    how to build it on my own. I would appreciate any hints.

    thxs in advance,
    Roberto

    Generally, a hifi solution is likely to involve digitizing, possibly
    compressing, and then sending via TCP/IP.

    Cat5 is too small a guage to handle speaker-level signals without
    significant loss.

    Line-level from your PC is another story. Cat5 can do a fine job with this
    signal... if you balance it at both ends. The balancing - usually with a
    small transformer - lets the close wrap of Cat5 cable pick up induced
    noise equally on both legs of the signal.

    The normal minijack output of a computer isn't balanced (and neither are
    consumer amplified speaker inputs). In this case, Cat5 would work as a
    very efficient antenna, picking up hum and noise.

    Check Belden.com for tech papers.
