The cable you will be using is coaxial cable. The quality of that coaxial cable is really determined by how far you need to go and potentially how much electrical noise you need to keep out of your system. Blue Jeans Cable really talks about the different types of cables they offer and why one is better than another. Why foiled/braided cables perform differently, etc. But, it all comes down to how much you want to spend and the quality you really need.
The Monoprice cables are perfectly fine. They do work well. But, the better BJC models are certainly a step up and worth it in an all analog system.
Digital coaxial cables are using the same coaxial cable that analog audio cables are using.
I typically just use mini RGB cabling for all my analog audio needs and it works just fine. For long runs I use a quality RG6 cable to go from my A/V receiver to the subwoofer.
