I'm using the CD-67SE with the DAC-AH. The DAC-AH provides a more believable soundstage and a more tube-like midrange and smoother treble than the Cd-67's internal DAC and output section. You'll also need a digital cable, and for a DAC in this price range I wouldn't buy an expensive one. I'm very pleased with an AR Pro Series II digital cable that's about $20 from Parts Express (part #181-866).
