Comparison of Anthem State A2 and P2

[shindsh]

Hello all,
Can anyone please tell me the differences between Anthem A2, P2 and MCA2.

I understand that P5 has 5 power transformers and it acts like a mono-block amplifier.
The MCA5 which I own has 2 power transformers and I was wondering if the MCA2 and the A2 will also act as mono blocks since I am looking for a two channel amplifier.

Currently Own:
Satement D1
MCA5 Amplifier
Pioneer Elite DV59-Avi
Arcam FMJ CD23
JMLab Electra 920 Fronts
JMLab Electra SW900
JMLab Electra CC901
Definitive BP30 for Surround
Cables: Synergistics Alpha Sterling

Wanted to get a 2-channel amp and use it to drive the JMLab Electra 920's in the front. And then get JMLab Electra SR900 for surrounds and use my existing BP30 as back 6.1 speakers and for DVD-Audio.

So in essense my current 5.1 system will become 6.1.

Thanks,
Shree
