I did a comparison between wiim pro and my MacBook out to my modi3+ and the laptop was significantly better sounding on my system compared to wiim. I assume usb output is better then the spdif output from the wiim, I did try rca output on the wiim as well, but same results. I sent the wiim back. Maybe if wiim comes out with a USB outputs it would be better.
