Great write up Martin, and echo's my own thoughts on the Audiolab.
To add to what you said:
Clean as a whistle and I'd maybe add that it's a detail monster.
Doesn't let the side down, even with an expensive Dac, which shows how bloody good the thing is.
Best CD playback I've had here at Gaz Towers,
betters my own Oppo too -a modded 203-, as a Redbook transport, even over i2s to the Dac.
Crackin' review to whet yer whistle if your considering a CD transport.

HINT: Dont buy a vintage CD Player, get one of these instead.
Sounds fantastic out the box, but can be given more Fizz with good cabling and isolation.
Co-ax connection sounded best to my ears, which makes sense as that output has had some time spent on it by Audiolab.
(coaxial socket is fed from a differential line driver: basically a much lower noise "balanced" connection)
I think the 6000CDT is a future classic.
