This makes the claim that cable actually makes a difference very unlikely. Also bear in mind that none of the manufacturer actually makes their own cables, they merely assembled them. This brings the question how do they QA their cable without a valid theory.
It is my understanding that a few cable manufacturers get cables made expressly for them to their specifications.
To my knowledge this includes Kimber, Cardas and Nordost.
I'm sure there are a few more that I am not aware of.
And there are many more that buy Belden or another brand of basic cables and put some nice mesh and heatshrink on them and mark them up, way up.
But whether they do or don't is irrelevant to whether cables sound different.
May as well just beat on Audiophile Op Amp and Tube vendors while we are at it for selling their own version of snake oil.
In the past I have rolled different Op Amps into circuits, but the differences are so subtle (when I hear them), that I am certain that I would fail any DBT.
In short, probably placebo, expectation bias, etc.
It would be nice to break down any DBT performed on various tubes swapped into amps, i.e. rigourously test the tubes to ensure the DBT is not testing/comparing tubes which have widely varying specs.
Some of the claims made by tube vendors alude to this.
One vendor of audiophile tubes states that it is difficult to make anything but generalities when comparing the sound of all Mullards to all Tungsols to all Sylvanias to all GEs to all Ken Rads to all.................etc.
