If your system is really "dialed in" and can throw images around like crazy, try any CD by Isao Tomita. This guy did (does?) classical and movie score material in electronic fashion (synthesizer), and everything I've heard is just completely wacky and wonderful - and mind boggling in terms of imaging and soundstage. I have only 2 right now: (i) "Snowflakes Are Falling" (music of Claude DeBussy) RCA/BMG 9026-63588-2; and (ii) "The Planets" (yes, Holst's) RCA RCD1-1919, but I have heard parts of some others, and all of them more or less remarkable. I'm not saying Tomita's music will end up being your favorite or even your cup of tea, although it is very "accessible", but if you want to impress friends with what YOUR audio system can do, as opposed to a Circuit City or Sam Sung special - Tomita will do it for you.
