User experience definitely heightens one's perception of the music they are listening to, aside from the usual variables introduced by circuitry (such as bass boost, or to some 'warm tube sound').
Take for instance, steak cooked the same way in two different restaurants.
- Restaurant A has good serving, a nice waiter, and the ambient light is low and mellow with gentle jazz song playing in the background. As the waiter brings the steak to you, he preps the handkerchief and lays it on your lap, positions the steak on the table, and introduced the steak to you like a detailed headphone review. His left hand whisks the air above the steak and agitates the mixture of smells in within the ingredient. With a gentle and professional smile, he then leaves you to eat the steak. Steak was amazing.
- Restaurant B is actually KFC and you brought your steak from Restaurant A. Steak tasted bland.
To tell you the truth, its how you prep your body before you do something. The priming. How supermarkets put fresh flowers in front of vegetable sections, they prime you into thinking the vegetables behind the fresh flowers are just as fresh and beautiful, and you feel that they are fresh.
It works, for everyone. Humans are suckers for user experience. I'm saying this through the eyes of a user interface design student's eyes, so I don't undermine or disprove whether different amps sound different because they are warmer or darker or whatever. Whatever floats your boat, I'm happy for you.
I mean come on, like, you get yourself a $1200 tubeamp, and you turn that **** on and it glows. You feel like you're some sort of 70's mad scientist trying to bring Frankenstein's monster to life. Ain't nobody within your vicinity could top that.
