Why a "digital" coax cable?


Sorry for the noob question, just trying to learn...

What is the difference between a 75ohm digital coax cable and a regular ol' RCA/RCA interconnect?

For instance, would there be a noticeable difference (improvement) between a digital interconnect and an Audioquest King Cobra for connecting the digital out from my Squeezebox (or CD, DVD, etc) to the digital coax input on my integrated amp? If so, how come?

Thanks all!

Each cable has its own impedance characteristics. Does your integrated have its own DAC? At the risk of suggesting the obvious: If not, use an analog cables between analog ins and outs. If yes, try the analog outs into the analog ins with analog cables, then try digital out to digital in with the digital cable. Use what sounds best.
Appropriate cables may change your perspective, but, I doubt it. It will probably steer you further in your current direction. I whole heartedly suggest you investigate appropriate digital cables.
