You're questioning whether cables have improved in 40 years? No. Cars, tires, toothpaste, lightbulbs, computers, phones, homes, (5000 items later) and speakers are better. Cables for some strange reason are just the same. Even socks are better. Underwear. But not cables.
Sorry, having trouble taking this question seriously. Its that far out there. Even with the cost inflation thing. Its just nuts. Cables are so much better its hard to believe.
Ted Denney alone has developed, brought to market, and improved beyond three different technologies- Active Shielding, Quantum Tunneling, UEF- each better than the last. Each generation so much better the worst cheapest version of the new generation outperforms the prior best most expensive model. That's improvement any way you want to slice it.
That said, never underestimate the talent of an audiophile to find some pure crap to throw his money away on. DYODD.
