I don't understand why people compare wires and cables to Monster brand stuff. Monster's stuff may look nice, but if you do the proper research, their stuff is mostly fluff. Cut apart any "oh-so-thick" Monster cable, and you'll see that it's mostly plastic insulation. The thickness of the metal wire(s) itself is practically of no difference than an Acoustic Research or other quality brand cable.
For audio cables, the only range that Monster cables perform better on is above 10MHz, WELL beyond the range of human hearing. I won't even go into detail about the "demonstration booths" that Monster has set up for video cable comparisons (i.e. they set up a booth comparing competitor's composite cable to their component cables - apples vs oranges!)
The only reason why they are still successful in being sold is the high profit margins that they provide by preying on ignorant folks. That is all.
