Hey Bruce - "what the f*ck is a "time-corrected cable"??? " - Maybe the GC guy meant, if you learn enough in "time", you won't buy this cable -
I think the main advantage to this type of cable is in the quick attach feature - kind of like those "slip over the wire and crunch" tail light connectors for RV places - not the best connection, but DEFINITELY the quickest. For stage use, I could see the attraction, although I've run custom cabling on stage for 20 years and NEVER had a problem with one of my cables.
For a studio, you would be better off permanently soldering quality wire and quality connectors together to make custom length/type cables that go where you want them to go without leaving 20 feet extra to pick up noise/get stepped on/look crappy...
For a clean, quiet recording system, there is no substitute for a properly thought out, competently wired, right wire for each type of signal, custom wiring job. We all know it's a PITA, but those who've tried shortcuts also know it's the only "best" way. If you're gonna have a semi-serious or better studio, learn to solder or be rich and hire someone else to do it. Period.
Just my un-biased, all-knowing, extremely modest opinion... Steve :=)
