Oh another cool thing about vinyl is the needle can couple to the environment too, try driving its case with another speaker or putting it in front of it's own big amp for feedback.

Also, I'm a little bit surprised that nobody focuses on more "out of the box" perception of sound. One can absolutely sense hgh frequencies, personally feel kind of like pressure where you can't pop your ears to equalize. Playing around with this feeling adds emotional tension and color to tracks.

Also, interference patterns are perceptible, and they sound kind of... Different from pure tones, idk.
