You can pick up a used PS Audio DirectStream transport for a good price. This unit buffers and reclocks the data which gives your DAC a better signal to deal with. I have one of these and I can vouch for it.
Or, if you go with a regular CD player and just use it as a transport you have way more choices. If your DAC has an HDMI input and you want to use it then you'll need a transport that has that capability.
