I agree with you 100% and I was referring not to them using good quality cables (I agree) but rather EXPENSIVE cables. Pretty, net jacketed, NICE cables. That half the time are crap and I have to loan them a GOOD cable that's not nearly as pretty. But yes, I did state it poorly, cable quality matters a lot less as a mic-level, low-impedance, balanced signal. Thus why DI's exist in the first place instead of bringing the signal back to the console as an instrument signal
Regardless, my general point remains, the "audiophile" crowd is hilariously gullible at times. $500 CAT5e Ethernet patch cables (serious product Denon tried to sell as receiver link cables at one point in history), "directional" audio cable, bogus pseudo-science words, etc. It's freaking hilarious - and ought to be illegal.
There are worse crowds. I dare you to look up such products as Asea (VERY expensive salt water solution sold as a nutritional supplement), Amway (LOTS of their products, but "Perfect Water" is probably the most ridiculous), BioPro (and all the ridiculous similar products, bits of plastic and sometimes metal supposedly infused with some type of voodoo magic to keep cell phone signals from harming you), and such similar (mostly multi-level-marketed) products preying on the poor, the gullible, the ignorant, the stupid, and the desperate. Ideally, you fit in more than one of those categories for most such products.
