Have transports improved for Redbook CD playback?

I’m going to compare my SF Ultra Jitterbug against my EA Synchro-Mesh/OTL reclocker using my CAL Delta into my Theta DS Pro Basic IIIA DAC. The Synchro-Mesh/OTL reclocker has significantly lower jitter than the Ultra Jitterbug on it’s output to the DAC, so the audible improvement of that upgrade should be evident. I’ll then move on to comparing the Oppo BDP-83SE and CAL Delta unit’s as transports feeding the Theta DAC with and without the EA Synchro-Mesh/OTL reclocker in the mix.

I recently bought a new Cambridge Audio CXU HD to use primarily as a transport.  Red Book CD's are better (more detail, huge sound
stage) than my Italian made Northstar transport, and Blu Ray movies are stunning! 

As an additional bonus I can stream from my computer (WiFi) through the CXU and straight into my Chord DAC which is MUCH, MUCH better than streaming through Roku (also WiFi) and the TV to the stereo.

For $700.00 I'm very happy!

Note: the CXU HD is strictly a spinner, it has no on-board DAC.

@fixedincome It seems as though the Cambridge unit is a complete blu-ray player (with built-in DAC). 

Nope, no DAC.

Ok. Bad look up from your earlier post. Thanks.
