Just wanted to post an update on where I ended up purchasing wire. I ended up with some CAT6 and speaker cable from Monoprice, Southwire RG6 QS and Monster speaker wire from Amazon, and CAT6, RG6 QS and speaker wire from Paige Electric. I'm in the middle of installation and all the cable is good quality. The Monoprice and Paige Electric cables are comparable. The Monster speaker cable is okay, but has a thiner shield then the others. My vote at this point though is Paige Electric if you can get dealer pricing....otherwise, Monoprice is a good bet for everything but RG6.
