Power Plants PS300?


Hello, The PS300 can handle 300w. So, my question is the max watts that PS300 handle is dependent on the actual watts you use or on the equipment rated power? Put it in another way, I have Classe CAV75 (75w x 6 = 375w plus other stuffs like pre, cd, dvd...it's over 700w). So, do i have to buy the PS600 + PS300 to handle all my stuffs or the power plant just depends on how lound of the volum I play? Please help and sorry for my English Thank you very much Tranle

I had my NAD T770 receiver (5 x 70 watts) and a Sony SCD-777ES SACD plugged into the p300. Speakers were 6/8 ohms. When listening to 2 channel sources there was no problem. I drew up to 190 watts. It was volume dependent and would be speaker dependent (4 ohm speakers require more watts). I used this set-up until my Bel Canto EVo 200.2 digital amp (120 watts/ch) was shipped. With the SACD and the digital amp plugged in using 6/4 ohm speakers, the p300 idles at 90 watts but draws up to 150 watts when there is alot of low output bass in the music. BTW - Digital T amps tend to be 90% efficient as compared to linear amps which are more like 40 - 50% efficient (class A vs class A/B).
