Apart from the L3000, which I like quite a lot, but their bass sometimes is excessive, the CD3000 would be a good choice IMHO. I didn't like the W5000 nor the W10 and haven't tried other closed AT.
The D5000 ain't bad, but even modding them (which works to tame the flabby bass of the stock model) still have annoying treble on most recordings, only very good ones sound decent. Overall I find the CD3000 more enjoyable and "righter".
Have you tried the JVC DX1000? Not that I'm advising them, but despite their flaws, they're quite fun depending on the recordings.
