I recently upgraded to claro halo xt http://www.newegg.com/Product/Product.aspx?Item=N82E16829271005 For some time now, I've only been using my sennheiser headphones. Which are decent enough headphones to notice the improvement after upgrading. But now its time for me to find some speakers. Never used optical devices for anything before. The card supports Dolby Digital Live, DTS Interactive, S/PDIF Loopback. Any recommendations? I also have some old rca speakers lying around. They haven't been used in about four years or so. Anyways, without a subwoofer they're too quiet to be of any use. For some reason I believed I could just use rca speakers without the subwoofer. I guess not though. Any suggestions on how to get these to work would be appreciated too. Sorry for my noobness. PS. For clarification - the users manual wants me to plug both rca speakers and s.woofer directly into the card. Rather than speakers to subwoofer then subwoofer to soundcard. Which means the typical 5.1 speakers at retail stores won't work. (The three green/black/orange or front/rear/sub cables.) The subwoofer needs to use a single rca connection to be directly plugged into the soundcard.
