Amplifier is now off the Power Conditioner

Yesterday, I replaced the wall outlet that my audio system uses to eliminate the switch on the bottom plug. Until now my tube amplifier had been plugged into the amplifier plug on my power conditioner, but now it is connected to the second plug via a basic surge protector.

I have b read that power conditioners are restrictive for amplifiers, but my first impression tonight was "wow". I doubt the wall outlet made the difference and it is possible that it was a good audio night (sometimes things just sound better for no known reason) so I will have to remain open minded for now.

It seemed that things are more clear, almost edgy, and the bass tightened up.

We need to distinguish between conditioners and regenerators here. The first simply filters the AC. The second regenerates it in a cleaner state and provides a store of energy for quick bursts of power so it shouldn't strangle the sound.

My amps have huge power supplies (I know, I built them). The output stage of each mono has >340 joules of energy storage! In a Class A amp! I find the sound to be cleaner and more consistent with the regenerators in place.

Well I'm running my 200WPC 833C SET monoblocks off PS Audio P5 power regenerators, and they sound better WITH the regenerators. Because of the power draw of the amps, I need to use one P5 per channel, but the dynamics seem to be better with the regerators. Perhaps that's because of the low output impedance and 50 Amp peak power capability that PS Audio claims for these units.
