This is only because you were not bypassing kmixer on the PC. The PC can sound just as good or better than Mac. With XP if you unmap the device, it is superb. The USB interface you are using makes a big difference too. If you are getting 24/44.1 rather than 16/44.1, the sound quality wil be great with Vista. Some USB devices do this.
The Firewire thing is filling the gap right now for 24/192, but it is not asynch. As soon as we have async USB supporting 24/192, it will beat this firewire. This year.
