another option, if you have a computer in your office, is to run your music off your computer. I have had the klipcsh 4.1 speakers for 3 years and they are the best. It beats everyone elses (on my dorm floor) system, boombox, stereo, or computer speakers by a lot
cost 300 dollars, probably less by now. You can probably get them on ebay too. Excellent for classical-good highs.
comes with sub and 4 speakers. There is also the 5.1 system, which comes with a center, but i believe that is unnecesary. Its extremely easy to set up, plugs straight into computer's sound card and you are good to go. Speakers are about 5 inches wide and 9 inches tall and can produce a lot of sound.
Also, you can put them in the 4 corners of your office and it will look nice(they supply you with long wires-just put them under the carpet,or near the ground
