Despite all my home stereo hi-fi knowledge and experience, I've never bridged the gap between my PC and my home stereo. I've got loads of music on my PC in SonicStage. I know that I can simply hook up my PC to the stereo using a minijack-to-RCA cable, but is this going to get me the best sound? Or will a sound card improve the sound quality? I've read some postings that seem to imply that a sound card would be redundant in this case. I'm confused by all the sound card info out there, so any help or advice would be greatly appreciated...
