I have a fully modified/upgraded P25 and have used many different cartidges, all with pretty good success. You say no price range, so it's kind of hard to narrow down. I'll list my suggestions from expensive on down:
Lyra Delos (overkill for this table, but very nice)
Dynavector 17D3
Sumiko Blackbird
Dynavector 20X2L or H
Audio Technica AT150MLX (currently on my table and WONDERFUL)
Grace F9E (my favorite moving magnet)
Your Fosgate will drive almost anything out there, so no problem on lower output MC.
