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,
Are you absolutely sure it is the amp? There are so many factors, the room, positioning of your speakers, the speakers themselves, and, of course, your source.
