Do Recording Studios Use Silver Cables

Not this week.

The engineers don't take the time to even match lengths, let alone brand.

I carried my own cables, mic pre, eq, level control, amp and speakers.

My company did studio installation. Some studios were very specific as to cable, others, not so much. Some studios went offline for a month or so to be rewired. 

Some studios had a wide assortment of mic and instrument cables by Belden, Mogami, Canare, Monster, AKG, Neumann, etc. Some musicians were quite surprised when we changed a cable instead of a microphone to achieve a particular tone.

Bottom line: It's the system.

In the pro world there is some acknowledgement that cables can sound slightly different, but by far the most important quality of a cable is that it is wired correctly and works.  They are tools in the music production arsenal.

I can't say for sure, but I imagine it has to do with the quality of the studio.

I know that Pink Floyd, when they were recording Dark Side of the Moon, went through every single cable they could get their hands on during the recording/mixing/mastering process in order to get the sound they wanted.

And recorded some of it and mixed at Producer’s Workshop, one of the least "advanced" studios in LA at the time. But oh, the sound...
