Help Choosing Tube Preamp

Hi, I'm trying to decide on a tubed pre-amp in the $400-500 range. Right now, I'm looking at a Conrad Johnson PV-5 or a Cary SLP-30. Anyone had any experience with these units? What are people's thoughts on CJ v. Cary in general?

I feel like there are two things pulling in favor of the Cary: (1) It's a more recent line than the CJ, (2) I have a Virtual Dynamics Power Three lying around that I could use on the Cary but not on the CJ. On the other hand, I keep reading about that "CJ sound"...

Any input and/or suggestion would be much appreciated. Thanks in advance!
