I have both the PS Audio 600 and the EP2000. The EP-2000 is rated for 2000 W, the P-600 will max out at 720w. The EP-2000will only put out 120V, the P-600 has an ajustable voltage, multi-wave, and balanced power. The EP-2000 is not balanced. The P-600 eats alot more power (for a given output) than the EP-2000.
I have experimented a great deal with these two and wound up using the P-600 for my audio only system, and the EP-2000 for my projection TV and all video sources. I cannot tell a difference between the two on VIDEO sources. I CAN tell a difference on audio. The P-600 is being used exclusively on an ARC VT-200 amplifier. The main difference is in high frequencies where the P-600 gets rid of the last little bit of hash in the treble.
Good luck!!!
