Like so many other pursuits in life, attitude is important. You have to discipline yourself not to get too finicky about it. I have powerful, revealing, accurate music reproduction, but I know I could go far beyond what I have, particularly when it comes to dollars spent.
One simple thing is to back off on the volume at the beginning of a listening session. Always leave something in the tank for the most exciting moments of a track. Treat it like sex, or the rev counter in your 911 GT3. If you take it right up to 8000rpm, you're not leaving much room for an encore!!
Getting into vinyl helps with this concept. I'm much more apt to listen to a whole side of music, put down the remote, read the liner notes, and enjoy the music.
