$1,500 to spend on a tubed full function pre

I was wondering if it is possible to get a full function tubed pre for $1,500 or less on the used market. I am looking for the pre to be as neutral as possible, but if it must go in either direction, a little to the warm side. I need the phono section to be better than my current phono stage (EAR 834p).

My current system consists of the following gear:

Silverline Sonata II speakers
Kora Cosmos Reference Monoblocks
EAR 834P w/ NOS Mullards or RCA 5751's
Linn LP12/Valhalla/Ittok/Glider
Theta Miles Balanced
Coincident Speaker, IC, and Power cords

Thanks,

George
