Sommer Cable:This is one very interesting high end cable:

It's about one year old cable type with
very low capacitance. I have only one 5 meter sample piece yet but found it interesting.
Galileo is interesting less expensive "high end" cable too for studio use. I like this cable and use it in the studio. It's also mechanically strong. Quite thick but flexible.

Sommer cable is not so old and traditional manufacturer like some others but they have very innovative attitude and interesting products. They make also nice low capacitance and star quad multipair cables.
About Gotham cables:Because i use cables mostly in live use the sound is not only aspect for selecting the cable. I've used Gotham in the past but found that they weren't long lasting in live use. The jacket is too soft and thin and breaks easily. It's the biggest problem. I don't understand why they doesn't make them stronger. Maybe in studio use it is not a problem. Gotham makes some special type with strong PUR jacket but haven't had possiblity to check it yet. (I've used Gac-2, Gac-1 and Gac-7 in the studio which is very good tube mic cable).
Anyway i try to keep more expensive and fine cables in the studio and use more durable brands and types on stage.... In live use i like very much
Belden 1813A. It is about similar diameter cable than Gotham (quite thin. The jacket material is really strong and durable but still very flexible. I've bought 6 rolls yet (100m /328ft) in couple of years... It stays flexible in cold winter conditions too... I don't know why Belden seems to be "out of fashion".
Not much audible opinions in this post but some experiences anyway.
