I've never heard a CEC transport, so I'm no help there.
I have however compared the Jay's CDT-2 MKIII to the CDT-3 MKIII in an extended comparison with a couple of friends. I personally would not spend double the price for the CDT-3, and in fact for period of the comparison there were times (most of the time actually) where we could tell little difference between the two. That said, they are both BRILLIANT CD transports. Another thing to consider is that the Jay's transports have an I2S output, which the CEC units do not.
Best of luck, and let us know what you decide
