Furutech GTX NCF receptical break in, how long

Most people don't listen to music actively. a quote I remember from an old Stereophile mag, "Most people like the idea of music."
Have others experienced this: in the general admission seating at outdoor concerts, most people are talking throughout the show so that there's a constant buzz in the air? When did this begin to happen and why?

Like evolution being a fact, some equipment,cables, fuses, etc need time to break in. Based on 15 years of listening, Its obvious to my ear that this is true. And, are you sitting down, my stereo sounds better after the circuitry has warmed up for a 1/2 hour or so. And still more madness. Ready for this one, get the padded room available, it sounds better later at night then the rest of the day.
To all you snake oilers, there's is more in heaven and earth than is dreampt of in your philosophy. Electro-magnetism, she is a strange and wonderful mistress
