In 1975 I was one of the 5 people at a cable manufacturing company Whirlwind Music that made all kinds of cables, splitters, PA snakes, etc, etc.
The company has grown to around 150 people and is still in Rochester New York, they are adding another addition on their factory building as I write this.
For about the first 12 years of the company I did all of the purchasing, which included specifying the cables and what went into them.
I bought many millions of feet of dozens of different cables and many millions of connectors of hundreds of types every year.
I spent an awful lot of time talking to the engineers at a dozen of cable manufacturers (Belden being the first) about how to make the best stuff and also making sure that it handled well in the hands of a roadie and felt good hanging off the mic or off the guitar to the musician.
There is tons of snake oil, and a little bit of truth in what you read from some companies trying to ask for high prices for cables.
What is so funny about it is, you can do any fancy stranding of cable you want, with all the oxygen free copper or fancy silver or whatever, then at each end you are going to connect it with a blob of solder!
Then you are going to use a 19th century designed 1/4" telephone plug to go into a guitar with a very primitive pick up device and then you are going to run it through an amp to a paper coned reproduction speaker device to make electric amplified music to add volume to what an acoustic wood box stringed instrument once made.
On top of that, most electric music instruments go through a half dozen effects devices half the time.
Most of the time when somebody makes a better amp or pickup or instrument, musicians are not happy because it does not sound like the past recordings from their favorite star musicians, hence the still overwhelming popularity of the Precision, Strat, Tele, Les Paul, SG, Marshall or Ampeg SVT stack, etc.
So, the whole thing is kind of a joke and is totally subjective.
