You know that cable "quality" is 90% bulls**t? You really need "better quality", or a lower gauge cable for when you really take everything out of the amp.
The higher the watts get, the "better", lower gauge cable you need, as long as you never had clipping because of your cable, there's no need to upgrade.
Anyway way there's almost no difference with these cables, a good quality Monster cable for 30-50$ will give you the same as the high-end 150$ cable. Since you'll never transfer this amount of "data", or lets call it watts.
Every average 30-50$ cable can push more than 1000watts, because instrument cables are heavy gauge, a 5$ cable can push around 500watts, and give you the same quality of sound in this power range as the 150$ cable.
Since these cable are analog, and not digital, it does matter what kind of cable you're using, but not that much.
Speaker cable gauge determines how many watts you can push, that's it, all this "carbon", "gold", "etc" elements are not important since it's not that the entire cable is made from gold, that would cost A LOT of money, just the connector.
I'm pretty sure you're not going to play in the Hammersmith Apollo, with 2,000-4,000 watts of amplification, or for about 50,000 people, you'll be fine with a 30$ cable, just pick if you want an angled connector, or not.
