The bat phono and pre are good matches. Plus both have balanced in's and out's which will marginally help some. Retube the p5 phono stage, especially the 6922's. It will make a huge difference. The Lamm is good, but the bat might match better for you...
FYI, the 50se is better than the 50. Also can update to the new 51se as well. good luck...
