For your proposed configuration, you have another option, and that is going with a "digital" amp. Considering your desire to ultimately go with the optical output of your soundcard, you might want to look into the Panasonic Digital receivers like the SA-XR45 or its replacement. The street price is under $300 and it really sounds fantastic, especially when feed a direct digital source where it does not need to perform an analog to digital conversion. I've owned one and it does sound very good, especially for the price. If you intend to use the Panny in a 2-channel only setup, get speakers that are bi-wire capable (4 connectors) and you can bi-amp them using the Panny's "party mode". Very nice!
Another much cheaper choice is a Griffin Powerwave. It is a 20 watt/channel digital amp that accepts either rca analog input or USB input directly from your computer. It can be had for $100 and it sounds pretty good. It is tiny (the size of 2 decks of playing cards), but will play plenty loud with efficient speakers. I would suggest speakers of 90-92db eff or greater.
For lots of information on both of these "new age" products, check out www.audiocircle.com and search through the "digital" forum and the manufactures forum for BoulderCable. Both of these units are modification candidates and Wayne at Boulder has worked with both.
Just another way to potentially go...........
