Doveman,
If that amp has Digital SPDIF in, you might concider just passing the bitstream to it for decoding. If the computer is lacking SPDIF, you can get a card for under $15.
I guess some people still do analog sound from the computer when just working with 2 channel stereo, but for digital multi-channel formats (like DD5.1 and DTS) ... the amp will work better (even if the speakers are small for now).
I'd love to get a AV amp one day, but unfortunately at the moment I'm just using my TV speakers for L&R and a Tripath stereo amp for the Centre. I'm also setting up an HTPC for my brother, who's even poorer than me so he'll have to use the analog outputs as well (again with his TV and a stereo amp), so it's quite important I get this working.
