I've been listening to the Soundstorm a lot lately, for music, games, and movies.
In music, at times, the highs sound a little bit tinny, but that's mainly because I'm used to an SBLive! 5.1, which is the ultimate in crap. It has very nice bass response, however. When playing Deus Ex, when I turn on my lamp, the bassy sound it makes when it powers on is beautifully rendered, with the sound feeling full, almost overwhelming. Frankly, I think it is a very nice setup. If you dislike it, the only reasonable alternative is most likely an M-Audio Revolution 7.1.
