Anthem A2&A5 vs MCA 20&50
 

I'm trying to decided which amps to go with the A series or the MCA series. I'm going to use them on Studio 100's. Basicly it's the same set-up as what was reviewed here on Avrev. My pre/pro is going to be the Avm50. Would it be overkill if I go with the D2 and the P series amps considering I'm using the 100's and not the S8's?
