I don't think the P4 preferentially improves hi-current components over low current or source devices. Beyond sheer current delivery, the P4 really excels at image solidity, nuance, and low noise. These traits yielded exceptional results with my Cary pre-amp, and Bryston digital components, as well as with my amps. Actually, I equipped my source components with P4's before my amps (which were on P3's) and without a doubt, the impact on the tube preamp and DAC were the most profound of all.
My suggestion is - P4 on highly resolving source components first, then on amps. But that's just with my system. Another option is to get 2 P4's, and try them around before deciding the best spot to start. Whichever way you go, you will quickly come to the realization that you'll need P4's all around!
And don't forget the long burn in. I invested in a Cable Cooker when I realized the path I was heading. It helps, but nothing replaces time.
