I agree with a lot of these people. I think that the best thing that you could do would be to buy a "cheap" Dolby Digital Receiver. I recommend spending some time at ubid.com. They have great deals on refurbished recievers there. I own a Denon AVR-65 Receiver that I got for $169 + shipping. It sounds great for a student with at budget.
My father has a good paradigm speaker setup. I highly recommend that brand. Buy two bookshelf speakers that'll sound like angels from heaven, and later as your needs and abilities arise, you can add a center channel and some big @ss fronts.
