I'm looking for suggestions for bookshelf speakers under $2000US. I've heard (and fell in love) with the Revel M20. I particularly liked it's ability to render bass (something I didn't expect from a speaker this small). I will use these speakers in a music only system and will not be using a subwoofer. I listen to modern rock/punk/pop if that matters at all. The more suggestions the better so I know where to go audition.
