right now im using an older cheaper pair of logitech 2.1 speakers, dont know the model #, but the 2 satellite speakers emit random buzzing, the left one more notably, and the sub always has a low freq buzzing/static like sound. i am looking for a speaker upgrade, mostly i listen to music and play pc games with the occasional movie/video, so i would like a 5.1 or higher set. my budget preferably would be around 200bucks or so, right now i am looking at the logitech g51's, they look pretty good; also considering the z-5500's although they are a bit over my budget. i am not in need of tons of bass, but i would like excellent sound clarity with crisp highs and mids. i will probably nab a new soundcard this summer, so far im considering the asus xonar d2x and the auzentech x-fi prelude, but i am open to any suggestions. thanks in advance.
