I've owned the Cambridge Audio CXC and the Audiolab CDT 6000. I like the Audiolab a bit better than the Cambridge Audio. But, it's not a huge difference.
Prior to these I usded a LG Bluray player and Onkyo 7030 both as transports and certainly the CXC and the CDT 6000 are MILES better than those two CDPs used as transports.
I have a Chord Qutest DAC and the CDT 6000 and the Qutest is really very satisfying.
I do plan on upgrading my DAC (5+ yrs with the Qutest) and going even higher with the CD Transport. Many choices, I'm not sure which way I'll go, yet.
