Pioneer PD65 or Wadia 850

Is this logical? I want to buy a great CD player to go direct into my BAT VK60 monoblocks, so I was thinking of buying a Wadia 850. But with the everchanging digital sampling rates I thought, why not buy a great transport and have the ability to upgrade the DAC as necessary. The Pioneer Stable Platter is one of the best transports out there. Wadia and Theta use them. I read a lot of reviews of other high end transports that seem to always have problems. The pioneer doesn't seem to have any, and I can pick one up for less then $500. If this is the way to go, what would be a good DAC with balanced outputs and a digital (or analog) volume control?
