DO YOU need a special cable to connect digital audio between devices?

Or can it just be a good qualily RCA audio cable since it has the same connecters?

There are digital coax audio cables, but I think RCA video cable will work too. Another option is optical digital audio cables.

BMW 7 series and Honda Civic are both 4 wheels cars. They'll both get you from A to B, just one does with so much more Joy and extra than the other.

you dont need a special cable, ive use regular audio cables many times and they work fine. your supposed to use 75ohm coax which is all that video cables are (atleast there supposed to be ). The special digital cable is just the video cable with a prettier appearance and much higher price.

You mean a red Honda Civic and a blue Honda Civic are both 4 wheel cars. They'll both get you from A to B, just one does with a different color. The coax cables for audio, video and SD component are exactly the same AFAIK.

Just to let you know, i tried to hook up dvd->receiver once with the poor quality/generic audio cables that came with an old vcr and it didn't work. Not all audio cables are 75 ohms. The OP stated good quality, so hopefully they do happen to meet the spec.
Just because they both happen to have RCA ends doesn't mean they'll automatically work.

Home is where my theatre is.

Most aren't, because they don't have to be.
SPDIF requires 75 Ohm coax cable....which is very common, but will also work, over short runs, using any cable.

You can find some decent digital coax cables for reasonable price. I have bought 6.6' digital coax from radioshack for about $4-5 and they are quite good.

Well......yes and no. To be technical about it, any cable with a RCA connector will pretty much work for video and subwoofer applications. However, there is a loss of signal. Whether or not you will see/hear it is something you will have to determine. Good quality Coaxil will produce a better picture and good quality subwoofer cable will eliminate interference and hum, especially over long runs. Check out Monoprice and Blue Jean Cables, both forum sponsors with links at the top of this page. They have excellent cables at very low prices. I especially like the Blue Jean subwoofer cable, it is very very nice. I got a 12' one and it is super well constructed. For those prices, there is no reason not to get good quality cables that are designed for the purpose you want to use them. Gosh, you paid the money for the receiver, DVD and display, why not get the picture and sound you paid for?

Thanks. Thats what I was hoping. I have plenty of good quality video cables now since from over the years, moving from componet video, to Svideo and now HDMI.

your component cables can easily be used as Coax audio or subwoffer cables. Bonus is one component cable, give you three Coax cables.
