Hi Graham,
The system you're thinking of should work very well. I'd suggest it would be very neutral with the Audiolab CD player and if space is at a premium the sealed-box design of the AE22's should help. The AE22's were also designed to work atop a mixing desk so placement on a unit, shelf or even bookcase is still viable and in some cases preferable (the mid alignment is aided by the surface underneath due to it's intended placement on a desk, although they also work perfectly well on stands).
From what I can see the CDQ has a few inputs on the back so you may well be able to use a hard-drive and turntable with the built-in preamp, though someone who knows the unit better may be able to advise more clearly on that...
Cheers,
Jim.
