My perspective is this: there are two separate arguments here, using the same words, and people keep talking past one another.
Many people seem to be against cables because of two main things: high (absurd) prices and crazy, hyperbolic marketing copy from manufacturers. This is often the main knock against cables, once you get through all the posturing and 'electrical engineering' junk.
Those that are for them can often come from the opposite perspective: spending money on something means it's good. More money means more good. And then the idea that if it's a professionally made, special cable, it has to sound good, so they listen, hear a difference, and start spouting ad copy.
I'm too cheap to spend good money on stuff I can make myself. So I experiment and have heard the differences in different architectures and materials while not being too attached to whatever I'm using. If I see a better idea or better materials that aren't stupid expensive, I'll try it and see..
Many naysayers walk in with a contrarian attitude, reacting to silly prices and hyperbole. Many supporters aren't critical enough of what they're hearing or separating cost from performance.
And then the are many like me, who are just curious and play around, keeping an open mind and not getting too wrapped up in marketing or prices. But our middle of the road view, that can accept the truths from both sides while dispensing with their absolutism, is mostly unheard because of the shouting from the fringes.
Huh, does that sound like anything else going on in our world right now?
