I have not played with the ExactPower, but I have auditioned a Power Plant P600 and the Equi=tech. I wound up returning the Power Plant and keeping the Equi=tech. I have a ET5R with Q & MSW Options. I understand that most would consider 230V 30A overkill for the entertainment system power until you hear the difference for your self. In addition, the cost was about $5K to implement rather than $2.4K. The final result using equi=tech offers approximately 4 times the available clean power vs. the power plant, making a comparable PS Audio solution twice as expensive.
