Can anybody recomend a nice set of speakers I could buy for my iPod dock, does the line out support those 4/5/6:1 speakers, surround sound? And if I connected them to my powerbook would the surround sound work nicely with DVD's etc. I quite liked the look of some of the Creative Labs models (bearing in mind I already have the soundsticks for my current iMac) Any suggestions guys? Thanks, Tom.
