To use async mode, don't you just need to install the driver? The other components like the motherboard don't matter, since it's related to the operating system. Do you remember which input setting they were using on the HDVD 800 in the store? If it was "Unbal" or "Bal" it was using the CD player dac, if it was any of the other ones then the HDVD 800 dac was being used and the difference you're hearing is from the music itself.
