Yup, I've been going with Monoprice for all my cable needs in the past, so I'll look to them first. Never tried BJ Cables so I should check them out as well.
Looks like most of you guys run 12Ga so I'll do the same. Might grab some 10Ga for the sub. Thanks for the tip about the subs possibly running on RCA cables, I never knew that. Are they just the regular old-school RCA cables?
GWCR, you mentioned about the relationship b/t speaker impedance and cable gauge. What is the idea behind it and what should I be concerned of? I would need thicker cable if using speakers with higher impedance? What might happen if I don't use thick cables on those speakers?
My room is 18.5' x 14.5'. TV will be on the long wall. Here's the actual diagram (http://www.avsforum.com/t/1459255/where-should-the-components-rack-go-plus-some-other-questions-layout-diagram-provided
), except that I've decided to get a low profile, long cabinet that will sit below the TV instead of a standing components rack sitting in the corner). So it looks like my longest speaker cable run would be no more than 40' (from cabinet to RL speaker on the wall). Like I mentioned, I will be running all speaker wires behind the baseboard and drywall, and they will come straight out from the wall through 1/2" wall bushings at outlet level that I already bought. I hope 1/2" is wide enough for 10-12Ga CL2 rated wires!
I still need to decide whether to place the sub in the front or the back of the room. What do you guys think?
Finally..about the budget...I'm not gonna say I don't have a budget. But I have not started researching into which speakers and brands are of the "higher than average" performance type yet, so I'm not sure what the price range for them will be. I will have to spend as much money as necessary to obtain that level of performance. And they probably have to not look too awkward with my existing room decor. lol.
