Phono pre recommendations for Technics SL1210M5G

From any Technics TT owners (running a 1210M5G, myself) I'd like to know what phono-preamp you are using. Currently have a Lehman Black Cube. Thinking that upgrading my phono-pre might be good bang for the buck. Considering a tube-based phono-pre. Budget not final but might be up to $1200. Cartridge is a KAB modified Stanton (nuded cantilever). My system is posted. If you have other recommendations, please let me know. Thanks in advance.
