Before upgrading to a fully loaded MP-1, I used a Plinius M8 and a Parasound JC-2. The Parasound was an especially good match with my MA-1's and I would have happily kept it if I didn't get a chance to hear a MP-1 in my system.
I have never heard the MP-3, so I can't say how it would compare to the JC-2.
