I'm not sure about the claim that a reputable CDP will outperform a computer based transport. I would imagine the most of the difference will be in the DAC and the downstream. That's not to say that all transports sound the same, but the difference in the transport is probably a lot more subtle than differences in DACs for example.
I have recently acquired Accustic Arts DAC, and it definitely improved red book over my Linn Unidisk SC. You might want to consider adding a DAC as well.
