P15 or P12 - best strategy for my setup?

Yesterday I attended a GTG together. One of the members there is an Engineer for a radio station and regularly attends these meets. The last time he was impressed by the P15 sonically so this time he brought a scope out of curiosity. I was able to snap some shots while he was doing it.

The first shot is AC from the P15, second is from the wall that the P15 is plugged into.
