Pass Aleph amps with PS300 or PS600?

I have an Aleph 3 amp and an old Aleph P pre-amp. The Pass Labs literature advises against changing power chords on their amps (they say they're designed in a way that the power source doesn't matter). I was wondering if anyone has tried a PS300 or PS600 with their Aleph amp. Has it made a noticable difference, or can I save some money and buy the smaller power supply for my souces and pre-amp?

Just a quick note to let you know that the PS 300 will NOT work with the Aleph 3 amp...it kicks it into the protection mode ( on the PS300) and shuts it down...too much current draw..over 300 watts at turn on, 290 at idle...you will have to save up for the PS 600 at $2K ....ouch! Regards, Eric

I stand corrected. Good to know the real story here. --Dan

Wait a second...my Aleph 5 drew 300 watts at idle per the manual, as I recall. The half-as-powerful A3 does also? --Dan

I have the Pass preamp, but the model 5 power amp. Recently acquired a P600. According to the P600 panel display the system (including phono preamp, CD and DAC) draw between 370 to 430 watts. The musical advantages of the P600 are as advertised. Give the P300 a try, it might work with the amp. If it doesn't, then you can either use it on the source component, or return it to PS Audio.

Have Aleph P and 2s (300w idle each), and wonder if there are audible benefits from these power-line devices. Isn't one of the benefits of that bathtub of Class A energy idling along to act as a flywheel (sorry to mix metaphors)? Anyone hear a difference?
