It's just worth agreeing with everyone else that while you have a lot of marketing telling you otherwise, the simple truth of the matter is just true simplicity.
Wire is wire.
You are shooting for copper wire of the right gauge, and if you get two wires, one that costs $1,000 for 10' and one that cost $5 for 10' and they are both 12 gauge, they will sound the same. Not just to your ears, but to digital audio test equipment. They can't measure a difference, you can't hear a difference, there is no difference.
I'm sure, if possible, I would not be the first to recommend that even the Monster cable that you claim is cheap, is still far more than you should have spent and if it was returnable, it would be recommended that you do so.
Here you go - 100' of cable, at about 30 cents a foot:

12 gauge - FTW!
Oh, and I actually use Monster Cable quite often because it works very well in-wall. Best stuff I've used so far out of a half dozen brands I've tried, I go back to them. So, I don't dislike Monster as much as some other people do. But, I won't pay their ridiculous consumer prices. Got 500' of cable for 190 bucks. shipped (14/4). That's better than Monoprice can sell it to me for. Still, on a one-off install, stick with the good stuff, but NOT the expensive stuff!
