CD Transport for Rega DAC?

I am about to receive a new Rega DAC to go along with my Rega BrioR amp and Rega RS5 speakers. I am looking for a decent CD transport unit and am considering the following: Cambridge Audio CD30 (recommended by Hawthorne Stereo in Seattle), Marantz CD5004, or Oppo bdp103. The oppo intrigues me because it has the benefit of being a great blu-ray player, but I ultimately want the best audio. Your thoughts would be appreciated!
