I concur. I can add about the M80 (fabulous!) that they are quite good even at low volume (I am a neighboor-friendly person, so unless they are absent, my listening is low).
I have the EP-500 instead of the EP-600 and it is also an amazing sub (not as great, but amazing nonetheless)... and it fits in an appartment!
As for dynamic range, check the specs of the receiver for a separate specs on dynamic headroom. You can find many receivers that are not all that powerful at constant rate, but have lots fo headroom for dynamics.
