I've read so many conflicting views on cabling and so I need some advice. 1. Speaker Wire. Some have stated that you need to buy Monster speaker wire. Others have said to simply buy 12 guage wire from Home Depot. Which is the better choice (or are there other alternatives to consider)? 2. Component and Digital cables. Again, some people swear by Monster (or some other big name) while others say just buy Radio Shack's highest quality cables. Which? 3. Coax vs Optical. I know this is kind of a moot point, but just to be sure... The guy at Radio Shack told me that you should go with optical and others have mentioned the risk for interference with Coax. How great is that risk and is it something to worry about (I'd actually prefer the coax because it seems more solid)? I'm not going to have a high-end surround sound system-- probably something like the Kenwood HTB-504--and my room isn't great acoustically (tile floor, big window and doorway), so that may be a consideration. My TV however, will be HD and the DVD player a progressive scan. Thanks.
