Tube preamp $1500-2000 for a thin sounding amp?


Hi, i'm looking for a good tube preamp that gives body to my sound. I have a Musical Fidelity A3CR amp and preamp and I think this couple is thin sounding, I want to try a tube preamp to see if I can solve this. I like my classical orchestra music to sound full bodied. I have a subwoofer, so the problem is not deep bass, but maybe mid-bass or upper bass (?). I'd appreaciate any help, I've got almost $2,000 to spend.
Thanks/cheers

Mattybunpkin, do you mean the AES signature preamp? have you had experience with it? Thnks
IMHO, try a Musical Fidelity X10 V3 tube buffer (~$275 used). I should allow you to experiment with different tubes which will affect the sound (Telefunken= neutral, tonally accurate, good bass; Mullard= warm, sweet, and smooth, Electro-Harmonix=, a good tube, modern day, highly available and CHEAP, and lots of others). It would be alot cheaper than purchasing a new line stage, and, if you don't like it (Stereophile magazine loved it!), sell it for little no loss. What have you got to lose? Happy Listening,
