I am planning to use the coaxial output with my new digital receiver (I'll get it in about 2 weeks), but am still kind of confused as to what cable I should use. As of this moment, I still have my Pro Logic setup, and am using the standard red/yellow/white cables to make the DPL connection. Could I just use one of those three cords for the digital coaxial connection once I get the new receiver? Or is there a more purpose-specific type of cable that I need? Also, I was looking around bestbuy.com, and I noticed they have a section for "audio cables" (click here), and a section for "digital audio cables" (click here) What is the difference in these two types of cables? Why are there cables designated specifically as "digital"? Is there any reason I should buy the digital type over the normal type? Thanks.
