I'm trying to get my next PC configuration figured out.

I'd really like to mount a LCR Soundbar on the wall just above my desk and below the monitor. There are some really nice non-powered LCR sound bars out there. Saw one on Parts Express, and some more other places.

My issue is...These things don't always come as an amplified speaker assy. How do I get the audio out of the PC, Amplified, then sent to the sound bar. Where can one get a 3 channel amp w/o buying a home theatre receiver. The PC Mobo has 3.5 mm Stereo, Center, and Sub analog outs.

Anyone have a recommendation?
