Default Pass XA 100.5 with Premier Power Plant?


I'm new here in this forum and (forgive me) a complete electronics rookie. I hope this is the right place to quote my first question:

Iím living in Europe and the nominal voltage in my country is 220 V; however; though Iím having a dedicated line installed for my stereo, the typical voltage is considerably lower at around 210 V. I just changed my power amplifers to a pair of Pass XA 100.5. I currently have connected just a DCS CD/SACD Player to the PPP.

I set up my PPP to deliver 220 V (also the Pass seems to be set to 220 V, at least its written on their back ;-)). The PP therefore generally has to generate an additional 10 Volt.

Under this circumstances would you recommend to connect also the Pass to the PPP or do they draw to much current from the PPP, especially considering the low wall-voltage?


P.S.: I cannot just connect the Pass to the PPP and give it a try as the cable lenghts do not permit that. Therefore before going out to buy new cables I thought about asking here ;-)

You can try it, but don't be surprised if it doesn't work out.

I use PS Audio Power Plant Premier with the devices connected to it: CD player, preamp, 50W Zen9 (440W idle consumption). Can say only positive words about PPP, it makes sound a bit more transparent, no decrease in the bottom end. But, my opinion, 500W load is almost a limit for PPP, inspite of 1500W declared. At 500W it already becomes hot and after several hours of continuos operation it can reveal some instability.

Hi Vladimir, thank you for your reply. I guess my system draws about 600 W idle, so therotetically the PPP should work; however, it (typically) also has to produce 10 additional Volts in order to reach the nominal 220 V... I guess in this case it will not be anymore able to reduce the THD of power line (from about 1,5%-2% to 0,3-0,5%) as it does currently.

I hope I can do some testing this evening at home!
