Monster cables are snake oil. On top of that most everyone I have ever tried is triboelectric. Meaning if you step on or tap on the cable, it makes a sound!
You are far better off buying Mogami, Proco or Whirlwind and dumping the difference into a set of strings.
I know, "you get what you pay for", but in the world of cables there are diminishing returns once you pay more than whatever Hosa costs.
Honestly, I have literally hundreds of cables (used to run a sound company). Two of them are monster and those were gifts.
As far as the soldering your cables thing, that is generally sound advice, but I get that some folks dont want to muck about with learning how to solder, stripping wire etc. I don't like to change my oil even though I can save $30 by doing so!
As far as lifetime warranty, that is a poor reason to buy a product. The product should just work, it shouldnt be something you have to keep returning. In fact, I'd rather NOT have to keep returning it!
Another issue I guess should be brought up is cable care.
I have cables that have lasted me 20 years. How? I do not "arm crank" my cables like a climbing rope or garden hose. I roll up my cable useing my thumb and index finger. Letting the cable memory guide itself. It is pretty much impossible to describe hold on...
Here you go.
It may seem like an anal nitpicky habit, but this prevents putting undue strain on the cable, AND if you velcro it after wrapping it up it will not tangle!
If you get in the habit you will actually be able to coil your cables faster than the arm crank method. Plus when you are setting up you can grab one connector and throw the bundle where you want it to go and it will unfold as it flies. It looks pretty sharp when you do that!
