Paradigm Reference Servo 15 Version 2 Subwoofer

Hello,
Does anyone out there own or has heard the new Paradigm Reference Servo 15 version 2 with the built in 1400 watt amp?
If so, what are your impressions of it?
Has anyone compared it with the original Paradigm Reference Servo 15 with the 400 watt amp?
If so, what were the differences?
Is the new version significantly better?
Thanks for your help.
