I used to own the Usher 520 together with the NAD C320 BEE amp. And I used to hook it up to a computer as well. =) I think it sound very nice at that time. I was using an M-Audio revolution at that time. I am not sure about your amp but does your support optical in? If your amp doesn't support optical in, then I think you will need a better soundcard to get better sound from your setup.
Currently I am using the Onkyo SE200 on Vista Ultimate. Not the cheapest option but it is the best sounding soundcard I've heard so far. I've been through SB Live!, SB Audigy, Terratec Aureon, M-Audio Revolution and SE 90. I think Onkyo SE 200 is worth every penny that I've spent on it. You might want to take a look at it here http://www.geekstuff4u.com/product_i...roducts_id=446
With a good soundcard, and your setup, I think you will just love the sound of it. =)
Edit: I've just checked through the NAD website. Your amp doesn't support optical in so I don't think you would have any luck trying to connect your Audigy optical out to the amp. You would need to use a mini-plug to RCA cable to use your Audigy.
