I use a Cary 306/200 as a DAC and a CD player. I am sure your results would be as positive as mine! The Cary was much better than the Lavry DA10 that it replaced or the CEC DA53 that I demoed.
I did find it was worth getting a good audio card (RME HDSP 9623) to help reduce the jitter and minimize computer setup issues. The PC still needs to be setup correctly. I recommend JRiver's Media Center using ASIO to bypass Windows problems.
I have not yet tried a Squeezebox or Sonos. I do not know how bad the jitter issue would be.
