All This Stereo, But No Party

This seems to be a problem with my audiophile obsessions. Even after I getting all of this great audiophile gear together, it still feels like a major pain when trying to get people to interact with the system and listen to their music. AppleTV seems like the closest solution with AirPlay, but what else is there out there? Surely there must be an alternative to throw a fun small party where everyone can listen to their tunes on a sweet system without having to whip out iTunes, throw on record after record, or plug in a computer with an atrocious RCA cable strung across the room?
