My attitude, is that there is definitely a law of rapidly diminishing returns. Whether a $3K cable is worth it over a $380 cable is entirely up to you, your system, your room, your sense of value. Do I think there is a difference? I consider myself lucky in that my ears are not acute enough to hear them after a certain point. And if I can I always ask myself if the gain is worth it. For me, the sweetspot for cables is about $1K. Anything above that only yields marginal gains to me. Do I think anyone is foolish for spending $10K on cables? Nope. To each their own because I am sure there are folks who think I am nuts for spending $1K on cables or for buying an expensive car...to each their own.
