  • coaxial digital audio cable

    Should I use a special cable for coax digital audio or any rca cable is ok.
    Some options is Auvio from radioshack and Monster cable 450 DCX.
    Thanks for any input

    Take your pick, you probably can't do better anywhere else. However, PE might whack ya $10 shipping, so if you have other stuff to order now is the time
    Don't listen to me - I have not sold any $150,000 speakers.

      I've never tried it but I doubt that shielding is even required with digital. One of the advantages to digital transmission is that it's almost totally immune to interference and will work with the cheapest grade of cable possible, not that you'd know that when retailers try to sell you a cable that costs twice what the DVD/CD player you're using it with cost.

        Any old RCA cable will work. You probably have a half dozen perfectly adequate cables laying around doing nothing. Use one for the Digital coax and giggle every time you look at the cost of that Monster cable.

          Forgot to mention it, but light pipe is better if you have the option. Since there's no mingling of the signal with the electrical ground it's quieter.

            Optical is less reliable in long runs, though we're talking past 25' . And its not the fault of the cable, its usually the transmission device can't push the signal reliably. (my portable MD fer example.)

            For long runs, carrying it on more fancy shielded RCA is usually more resilient against signal drops. For short runs, i don't think it matters unless there is an interference problem being fought also.

              For sure, otherwise there would be no FiOS. My assumption is that the ground loop woes caused by TV cables are eliminated with FiOS, that is if they didn't mess up on the FiOS to cable conversion at the entry point.

                "Special"? No, but it should be a 75ohm cable and connector. Unfortunately most consumer grade gear doesn't adhere to the S/PDIF specification, so in some ways it doesn't matter ... but if you don't want to compound problems - internal reflections along the transmission line - get a true 75ohm cable.

                    I second this vote. Their Belden stuff sounds fine and has been trouble free for me. It's getting expensive to buy from them these days however.

                      While it's true just about any cable will work, the S/PDIF spec is 75 ohms. Additionally, in the most commonly used digital audio transmission formats like S/PDIF and USB there is no error correction. Now, whether any of this is audible or not is subject to the usual endless debate :D

                        Do any of you guys use www.monoprice.com? I've ordered HDMI and some speaker cable and found it to be top quality, and almost always lower prices than anyone with cheap shipping.

                          I've used mycablemart.com with great results before PE's HDMI cables got reasonable. They're in MN I think.

                            I have used monoprice. The cables work well for me. The only con for me is their premium cables generally are stiffer than I would like. Still the price is attractive.

                              If I recall correctly, SPDIF signals are in the 3MHz range, which is low enough in frequency that any cable should work over a short distance, which is why you normally find digial coax used with an RCA connector. For a long run, a good 75Ohm cable with 75Ohm connectors would be preferred.
