I am thinking getting the XDA-1 DAC too, but the USB hardware support up to 48kHz / 24Bit of the XDA-1 make me think again.
The only way to connect your laptop to the XDA-1 is using USB.
In case, your laptop has TOSLINK optical output. I believe the DAC in your Yamaha receiver is much better than the one in your PC, use it connect direct to your receiver. This way, you should have much better sound by using the DAC in your receiver.
I am not so clear about the specs, but base on your Yamaha spec: D/A Conversion 192 kHz / 24 bit, it looks better than the limited of the USB of Emotiva XDA-1 (USB hardware support up to 48kHz / 24Bit)
I hope this help
