Need some recommendations on Tube Preamps


I recently bought a pair of magnapan 1.6QR which are outstanding speakers. Although this may not have been beneficial for me but when I auditioned the system used was accompanied with a tube preamp. I currently have solid state Bryston BP20 and 3BST system. Sound is great but tube preamp was sweet sounding. My question is what would you folks recommend for a tube preamp paired up with a Bryston 3BST? My price range would be around $2000.00 and my listening pleasure is opera or classical! thanks

Thanks for the responses, great start for me to review these products. The system that was used was Vintage product dating back 40 years! Tubes is new for me and when we plugged the transistor integrated amp it was still nice sound but the tubes were better. Unfortunately many have told me that TUBE amps are not good with Planar speakers which is ideal for me since I want to keep my Bryston Amp to drive the speakers! If I had another question it would be Balance or single ended?
Yesterday I heard a pair of your speakers with a Rogue preamp (the Perseus model) and an Adcom 5802 amp (the Nelson Pass one). I was very impressed. The Rogue is in your price range - check out their web-site.
I suggest Conrad LS17 also, very musical preamp. Try MKII if you can afford it.

I'm using an Eastern Electronic MiniMax pre with my Krell KAV-250a to drive my Mg1.6's. Sounds glorious!
