OP -- is the application strictly limited to playing CDs, or do you think you will be getting into streaming later on? When I was shopping for an integrated amplifier, the dealer played music via the Luxman D-03X. To be honest, I wasn't impressed. The dealer suggested that the dac-only Luxman model, DA-06, although discontinued now was significantly better. I bought a used one on his recommendation and absolutely love it. I feel the sound signature lies somewhere in the middle ground between R2R and Delta Sigma DACs, i.e. retains the rich, smooth character of R2R, while not sacrificing details like some R2R dacs.
Either way, I agree with other posters to keep the transport and DAC separate.
