    Hi,
    Which would you recomend me to use for sound coaxial or optical ports?

    Thanks...

    I'd especially recommend the post by "iwilson" under the first link... approximately 7 replies down :) ;)

    I connect my Dvd player to my home cinema amp using 50ohm IXOS cable when its supposed to be 75ohm but have i detected a difference in sound ? nope so i guess its all just hype and perhaps the only thing better on some cables is the shielding

    Sample Digital Data Via Coaxial:

    Sample Digital Data Via Optical:

    Sample Digital Data Via Uber Monster Ultra Pro-Optical Ninja Reference Optical Cable at £100/m:

    :D

    A digital connection that is working at all is equivalent to any other.

    The differences are only in the physical properties of the two types of cable not the sound.

    Coaxial is cheap as chips (or should be ;) ) and is absolutely fine for most purposes and doesn't mind being bent round sharp corners :)

    Optical can help if you have an earth loop (no ground) or over very long cable runs, and it's immune to electrical interference.

    I recognise that sample, is it not a bit of Are Friends Electric by Gary Numan ?
    I've tried a good few cables and never heard a difference if honest.

    Coax is better = more direct (no conversion required). Optical is indirect (goes thru 2 conversions), hence quality los is increased. However one does need a good and short coax.

    A coax sounds more open than an optical one.

    spdif to i2s, 1 conversion
    toslink to i2s, 1 concersion

    processors / DACs do not use SPDIF internally

    ST Optical also goes through this conversion process as well and is a better link. Why?

    It isn't about conversions etc just basic engineering.

    All coax needs to do is:
    75 ohm plugs (preferably crimped), 75 ohm cable (coax) with a linear CI along the cable for best performance (most coax isn't). Properly screened and connected both sides. This costs peanuts to do correctly. Speak to Elliot for the best of the best. You will be surprize how good and how cheap it is to do correctly. Keep it as short as you need.

    Optical might help more in noisey environments due to it's better isolation.
