I can't comment on your Hovland, but I can say that anything under my BAT preamp and phono stage makes real difference. I've tried the Black Diamond Racing cones, the DH Cones and Squares and Symposium Rollerblocks and Symposium shelves.
I personally like the Symposium stuff the best. It's an immediate boost-all over. You may just have to try one or two things...
