the only thing i like about the z5500 is the sub. other than that i think he speakers are crap, the drivers are to small and you loose all your mids. i myself use the Klipsch pro media 2.1. the quality kicks the ass of my z5500, even though the sub is only 6" in packs a HUGE punch. unfortunately i cant hook up my z5500 sub. but even in a 4000sq foot house that i live in, my little 6" shakes the whole place, and my z5500 shakes mine and the house next door lol. and i never had to burn in my klipsch. but if i want real sound quality i will hook my pc up to my klipsch palladium series and listen to the most flawless audio there is. unfortunately its hard to find songs with really high quality, 128bit music sounds like garbage.
