Have you tried any of the MC O.5 plugged into the P10? If so how many and what was the results? Do you use the multi wave feature on the P10?
I removed my PSaudio P10 from the loop, plugged the Hemisphere straight to the wall(non dedicated line 15 amp) The P10 fed the Hemisphere for more than 300 hours. with the P10 no longer in the loop the Hemisphere as about 30 hours straight to the wall. the sound and sound stage has changed. The Mid range and highs have increased quite a bit very smooth and clear not harsh in any way shape, opened way up. The sound stage has gotten wider. Very happy with the mids and highs. The tv picture seems to be much sharper than before.
On the down side the base has lost a little, it just not have the clean or detailed base as before the change. May be not as deep as before or tight. Going to give it some more time, before i make a decision on putting the P10 back in the loop.
I have add 4 more MC O.5 to the power line that feeds my amp for a total of 7. The line that feeds the Hemisphere has always had 3 MC O.5 on it(same for the P10 when in the loop) The Hemisphere has 2 MC O.5 plugged into it.
Enjoy Pete
