Tube Preamp to go with Bryston SST2 amp and Magnepan 1.7i speakers


Hello, I'm looking for a good tube preamp to go with a Bryston SST2 amp and Magnepan 1.7i speakers.  My budget is $2000-3000.  I like to listen to a wide range of music, from Dire Straits to Blues to Jazz. I have my stereo in a medium sized room, and listen at moderate levels.

Thanks for your input!

What pre are you using now and what kind of improvements and sound characteristics are you looking for?
With a Bryston amp and 1.7 Maggies I'm thinking about a good tube pre-amp with a good top end. 2 or 3 K is not much budget. I think I would try to demo some at home before I pulled the plug but the Quicksilver is a good starting place or perhaps a used Audio Research. 
Thanks for the suggestions so far everyone!

soix - the pre I'm using is a Schiit Saga.  

I'm looking for better soundstage and instrument clarity.
