Audio out for cable box to surround receiver: Digital audio or analog?

I am preparing to run audio cable from my cable box to my surround receiver. I have 2 lengths of RG6 cable with RCA connections on both ends. I wasn't sure if I should run a single cable from the Digital Audio Out on the cable box to the Digital Audio In on the surround receiver. Or, if I should use both cables and connect the analog (ie, red/white) jacks between the box and the receiver.

One instinct is that digital will be superior to analog. But, another, more primitive instinct is that two is better than one.

Which connection will give me better sound?

Thanks,
Guy

Digital coax is much better than analog RCA.

Digital is by far better when it comes to audio wiring.

That one digital wire can do 5.1 to 7.1 audio. The two RCAs can do stereo..maybe simu-surround (PLII).

I guess it also depends on your programming too. Some programming only has stereo broadcast..I've noticed some of my free OTA HD have 5.1 listed.

The RCAs can carry full surround in 5.1, but the separation isn't as good, the noise floor is higher, and the bandwidth can be limited.
