OK guys & girls, I'm going out on a limb here but well, what the hell:
Although I have personally only been involved in the design, building and commissioning of a few small studios here in the UK I have worked in a fair number of top studios including those of major names
Not one of these fine establishments has to my knowledge ever used any of these 'esoteric' cables in the construction of their 'world class' facilities!
No indeed, in fact they tend to use just regular high quality production cable from reliable manufacturers
Some of the TV studios I'm talking about contain several miles of cabling to interconnect their various studio components
Don't get me wrong, I have nothing against the odd 'big name' guitar lead or two but really it's all just a big hype trick
If 'Dire Straits' can record and master such superb sounding albums as 'Brothers In Arms' in studios wired with regular star quad mic cables then it's good enough for me - end of story
My advice is to teach yourself to solder, buy a reel or two of good quality cable and a box or two of good quality connectors such a 'Neutrik' and get stuck in - you won't look back once you've done it
Cheers
