More clarity I guess? If you can't hear a difference I wouldn't bother.
Yes, for sure.
Where were you when you tried out the new cable? What guitar and amp were you playing?
I ask because the first time I tried a Monster cable I was in the studio. My cables were good...I soldered them myself and used good cable and good ends...but the studio engineer felt that the new Monster cables might be better, so he gave me one to try out.
I was playing my Les Paul through a nice Duncan tube amp that I used to have and I got to hear everything through an amazing studio system.
The difference between my old cables and the new cable was like night and day: better clarity, better low end response, and even a touch more db in volume. We could hear it with our ears, but just to be sure he hooked up a spectrum analyzer so we could see the difference on a digital graph.
What we heard was exactly what we saw on the red leds.
He let me keep the cable for free (I still have it after nearly 20 years) and have been a convert ever since.
A good cable is a good cable. Doesn't matter if it cost $10 or $100.
