Good preamp for Vandersteen and McCormack

I currently have a McCormack DNA-1 Deluxe feeding my Vandersteen 2CE sig. Currently I am using a Rotel RC995 preamp, left over from my old system. What are some preamps that may match well with my system? My roomate uses a DIY Bottlehead Foreplay for his Mac/JBL setup, and I am beginning to understand and appreciate "tube sounds".

I don't want to part with my McCormack, and my budget is less than $1000. I like listening to acoustic music, and I love my rock and electronic stuff too.

Should I stay with SS or would a tube preamp fit the bill? I know such questions are hard to answer, since they are based on preferences and other issues that are hard to quantify. What are some good suggestions? Personal experiences would be helpful.

Thanks a lot...
