Let me preface by saying I'm no audiophile. That said, I don't want to have speakers that get fuzzy sounding when it's 3 notches from top volume. What I'm looking for specifically is an iPhone 4-compatible sound system that has a dock for the phone to sit in, and wireless streams music either via the dock or via Airplay to the speakers. Multiple speakers are a must, as looking to have it set up throughout my basement (roughly 500 sq. ft.). I'm considering just buying an old Apple iPhone dock and some Airplay compatible speakers, but wouldn't mind having an all-in-one set up. Budget would ideally be <$300, but if it's sweet enough will spend more.
