If contradiction is present, often too is the use of logical fallacies.-10 ft max RCA cable based on a fringe case of a super high output impedance preamp.
-All XLR cables sound the same.
-If you don't agree with the above the issue is with your components.
-A vast majority of RCA cables are coax cables.
The Strawman is in use in the quote above.
10 feet is always a good recommendation because you can count on it to always work. I never said it was the limit. You came at that from the other direction and completely missed the point as a result. I never said for example that a 16 foot cable wouldn't work. Heck, if you're careful you can run 30 feet of the stuff. But if you're not careful then 10 feet is a very safe rule of thumb. When you distort my arguments, at first I'm patient because I don't like pointing out to someone that they used a logical fallacy. They usually don't take that well. But just so you know, the use of a logical fallacy in an argument means its false by definition, so not a good debate tactic.
Nor did I say all XLRs sound the same. What I've said is that the balanced line system is very good at eliminating cable artifacts- that was one of the reasons it was adopted and its proven itself very good at it over the last 70 years of high fidelity recordings. If its set up properly, its easily demonstrated that most cables will sound identical (there will be some exceptions as there is a Bell curve, and of course expectation bias). But if that system is not in place you'll hear differences. This is so very easy to demo!
I know of a few RCA cables that are not coax such as the woven Kimber cable. But it is correct that the vast majority of RCA cables are coax, which is to say that there is a shield around a conductor- or perhaps two conductors, one of which will be tied to the shield at one end (this latter type of cable is really limited to high end audio use, which in the scheme of things is a tiny proportion of all RCA cables made). At any rate, after being asked a simple question, I answered it simply and correctly that the shield is responsible for the capacitance of the cable. Of course this isn't correct with something like the Kimber, but in the big wide real world, cables like that are so rare that they are so many signifcant digits past the decimal point the don't alter the accuracy of my answer.
