Cheaper than cheap: Turn off the lights. I don't know why this works (probably by removing distractions?), but I frequently find I enjoy the sound more with the lights out.
I also find that cleaning my ears with one of the ear wax removing drops from CVS usually helps when my system doesn't sound as involving as usual. I recommend trying this if you've never done it before, especially if you wear earplugs occasionally.
