Need help setting up new pc audio system


Just purchased a new desktop - Velocity Micro Edge Z55. Didn't get either of the two offered sound cards - both Creative labs products. Went with integrated sound option with intention of purchasing after-market sound card.

Would like to get top notch 2/2.1 channel audio without going too crazy with the $$$. Looking at several sound cards by ASUS and Auzentech and HT Omega. So many options - can't figure out which one to buy. Can someone point me in the right direction. Should I run Firewire/USB out to external DAC? I would prefer to avoid that set-up unless its really necessary.

Also, very interested in new active speakers. Presently have Cambridge Soundworks Microworks by Henry Kloss which actually sound pretty amazing for what they are. Nevertheless, I'm sure I can do much better. Looking at Audioengine 2 which are very well reviewed. Also looking at Dynaudio MC 15 and Quad 11L active. Would love to hear from someone who has heard all three.

Thanks.

Firewire to firewire/spdif converter and then any dac you want. Not limited to dacs with usb input and not draining cpu cycles. USB, even in asychronious mode, still transmits packets, while firewire transmits streams.
"Cambridge Soundworks Microworks by Henry Kloss"

The only thing is that, the MicroWorks II is equipped with a less-powerful amp that delivers only 20 watts to each satellite and 40 to the bass unit, far less than the original MegaWorks 210D's.
So, new pc is here.

Inputs of old sub disintegrated, so definitely going to get new speakers. Have a pair of Audioengine2's being delivered tomorrow, but I have a feeling they are not going to cut it. In the meantime, I am really focusing on the Dynaudio MC 15's.

Question is do I go with a good sound card, or with USB out into Cambridge DACMagic, or something else. My concern is that while the unit is well reviewed, the USB input option doesn't seem to be so great. I'm not sure I want everything upsampled, plus if I understand what I am reading USB is limited in terms of its output resolution. So any high resolution audio files on my hard drive would be downsampled and then upsampled. That doesn't seem very intuitive.

Are there any external DAC's that will accept a firewire input that don't cost $2,000?
all you need is a firewire to spdif convereter-$200 (MAudio) - then, you can get any dac you want, not limited to USB or firewire input.
