NuForce Power Conditioner

I would like to get an opinion on power conditioners for a pair of NuForce 9 SEV2. I am currently running an older Chang Lightspeed that feeds my entire system. The system sounds good but I wonder if maybe isolating the amps from the rest of the system would yield superior sound.

System: Esoteric SZ-1, MSB Power DAC, BAT VK 31SE, NuForce 9 SEV2 all JPS wires and Coincident EIII.

Thanks for any imput you can give me.
