I have a Cambridge Audio 640p (black) that I may be looking to sell here soon. I've been using it for about a year and it's served me quite well hooked up to a Rega P1. I've been looking for a vintage Marantz receiver to hook up the turntable to directly. When I find one (hopefully in the next week or so), I don't anticipate a need for the pre amp.
Let me know if you have any interest.
