Hey guys, I'm looking to pick up these speakers to use with my MBP and I've got a few questions: 1) I'm assuming I can connect them via the headphone jack. Is that cable included or would I have to buy it? 2) Is there a way to connect the Soundsticks with the optical port? Would that sound better? If so, what kind of cable would I need? 3) I'm currently using these. I'm assuming I'm going to be hearing a massive improvement, correct? 4) Anyone have any alternatives to Soundsticks? Preferably cheaper, heh. I'm big on aesthetics Also, in case it makes any difference, I'm using a first-gen Unibody MBP. Thanks for the help!
