I did just that a few nights ago. I have a pair of Paradigm Titan v.2's that were sitting around waiting to be wall mounted as surrounds in my HT system. I have this Cambridge Soundworks 5 piece speaker package for my comp - 4 cubes and a "subwoofer." Anyway, I hooked up the Titans as main just for the heck of it. The Titans are broken in and sound wonderful in HT. The results were interesting. The Cambridge cubes sound boxy, tinny and congested. The Titans sound big, wide and painfully detailed. They picked up huge amounts of source crap that I could never hear with the cubes. Also, the amp which is integrated into the "subwoofer" is a real POS. I am not sure where I fall on the whole mid-fi vs. hi-fi amp controversy, but the distortion from this ultra low fi amp (guessing 5-10% THD), hitherto masked by the craptacular Cambridge speakers, had me nautious after about 2 hours of game playing. Base on the Titans was Godlike compared to the cubes, especially at 2 feet distance. My opponent's grand cannon firing at my rhino tanks in my favorite online game Red Alert 2 reverberated through my spine. The "subwoofer," with its anemic 6 inch driver, was nowhere to be heard. Gunning down street thugs with a sawed off shotgun in Max Payne left me shell shocked. After 2 hours, I could no longer bear hearing what the cubes had so mercifully concealed. Anyway, there is a question in this. I have a Sound Blaster Live! Audigy card, and I would eventually like to hook up say 2 pair of Atoms, and an 8" sub. Can I interface a budget receiver (~$200) with my sound card and make this work? If so, what should I buy?
