I'm going to change over to a McIntosh 7108 multi channel amp to run the top and probably just use one RAMSA WP9440 on the bottom. Using two is overkill. I walked outside when it was playing at a moderate level, and I can't believe how much everything on the outside of my house vibrates. That can't be good for the house.
I don't know if this is any help but I run 4 way active with a Marchand XM44 3 way crossover, the Crown class D on the bass has its own crossover.

With the DAC having such a large influence on the sound I find I am getting some nice sounds out of my system.
