Pass Aleph amps with PS300 or PS600?

I can't comment on the sonic effects with an Aleph amp (used to hafve a 5), but it makes quite a difference with an X-150. I think there is a reasonable chance you'll be able to use the Aleph 3 successfully with a P300, along with your front-end gear. You may need to get the fan kit for the P300, but try it first without. Unless the P300 shuts down with the Pass (not likely, but no harm in any case), you'll be able to see for yourself if it makes a difference with the amp. In the end, if you feel you need more power headroom, you can upgrade to the bigger Power Plant, taking advantage of PS Audio's 30 day trial. --Dan

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.
