68pete,
Nice to know another audiogonner has the P-10. No, I have not tried the MC-05’s plugged into the P10. I have 9 of them plugged into the outlet that the P10 is plugged into. That may be something for me to try though.
From the P10 I am using the CPT 300 balanced power cord into my DIY power strip. From there I have all of my Cerious Technologies Graphene Extremes plugged into the strip for my front end components. I will add to this that when I plugged a few MC-05's into this power strip the sound became louder but it lost it's purity, so I put them back at the wall outlet(s). I wonder if the balanced power did this?
I am interested in your findings with the Hemisphere vs the P10.
