I've been using this cable for a while now, both for live stage work, in the field and in the studio, and I'm very happy with them.
There are little noticeable sonic differences between very cheap and more expensive cables. The difference is all in the sturdyness and build quality. More professional and pricier cables don't break that quickly, and are much more reliable. And if there is one thing you need when working in the field, or for a live show, or even in the studio, it's reliability, even when the cable in question is submitted to a fair amount of abuse. No matter how good your other gear is, if the cable connecting it doesn't work, there won't be any sound.
Cordial is one of the brands that is reliable. Not only don't they break quickly, the flex cable means it remains easy to roll up and quickly roll out even after using it for a fair while. The cable has almost no memory, and smoothly follows the musician wherever he goes on stage. And the Neutrik connections remain smooth after countless plugging and unplugging. Furthermore, this cable has adequate RF rejection. And it is still quite affordable.
