Cary SLP-2002 or SLP-03?

I'm looking for a preamp that has balanced capability, and also has a HT pass-through. There are several out there, but the Cary ones seem to be match my needs well, and I figure that they would match my Cary CD 303/300 well. Used, the SLP-2002 and SLP-03 are in my price range; the SLP-05 is not...

Can anyone speak to the sonic differences between these two preamps? There is precious little information available about these, and I have found none comparing the two.

I'd be interested in feedback on these, and alos on any other pre's in the $1500 price range that might make a good alternate.

Thanks,
