I 've never heard the MA-1, but I have the the MP-3 and it sounds fantastic. I can't see going wrong with the MP-3. You can get the MP-3 with or without phono section and you are on the right side of "diminishing returns". The MP-3 is wonderful for tube rolling, you can really tailor the sound to anything you like (some may see that as a blessing or a curse).
