Cambridge CXC transport only is a new one that's very good for the money. And I've got my eye on a Denafrips Avatar one day.
Many, at the moment, I'm using a very nice sounding old one Arcam Delta 250 transport only. So far the best one I've had was a Wadia WT2000 two box transport, trouble was it had a Sony KS151A laser, and they are like hens teeth now to get, so I sold it while it was working good. Another good one was a Pioneer PD77 stable platter, same problem getting a laser now.
I would stick with CD only ones as some hybrids have different lasers to play other formats, and to me don't sound as good as dedicated cd ones.
Cheers George
