i haven't tried the power amp yet, but i got the CDQ recently and love it. (i'm using it with a Linn power amp at the moment, but i'm saving up for some 8200MB's)
the cdq works great with my Linn, and i tried it at the weekend on some other kit, including a £4.5k Leben valve power amp (as a pre and cd player) and an Airtight integrated (just as a cd player). it sounded fantastic with all the kit i tried, though i think the Leben shaded it. the pre worked really well, and compared favourably to a couple of £2k deidcated preamps with a turntable as source.
can you demo it? if you can, then have a listen with a couple of different amps and see what you think. i don't think you'll be dissapointed.
