The monster cable is good stuff if really expensive. The quality of cable you need is NOT a simple answer because it should be in proportion to the rest of your equipment. If you have really good high end stuff you would want to get cables to match.
The best cables if you have to run any distance are actually home made with coax cable and special connectors, that's what they use in the TV studios and it's cheaper than monster cable. If you do a search on some of the home theater forums you can find instructions. I had to run a cable about 35 feet and that is how I did it, works perfect.
