Everyone should buy more expensive cables, especially if they can't hear the difference between what they already have. You have to consider directionality, skin effect, interference by gamma, cosmic and Wi-Fi signals plus secret government wavelengths.
Then there's 2G, 3G, and 4G. Of course the game's up when 5G comes but in the meantime I advise everyone to send every last cent they have on the most expensive cables they can find. And every time a more expensive cable comes along you must buy that too.
You just can't take any chances these days. The fact that some say a straightened coat hanger sounds just as good as $1000 per metre cable just shows how unrefined their palette must be. No, I don't need any figures on resistance, induction or capacitance. I prefer to trust my ears. I had them recently checked only 20 years ago.
Now pass me another glass of Screaming Eagle Cabernet 1992. At $500k a bottle it's got to be worth every cent.
