I know some of you here already use a PS Audio Powerplant but two weeks ago I received my PS Audio Power Plant P3 and I couldn't have wished for better results than I got. I was really shocked (in a positive way) that the already so very good sounding D-Premier could improve this much from AC regeneration. Best of yet, the distortion of my AC was at an already low average of 1,6%. The P3 lowers it to 0,1%. Also I already had a dedicated AC circuit and above average quality power cables/AC receptables.
If you have the chance I would really recommend to try one for yourself. Macroµ dynamics, soundstaging, ease, resolved detail, timbre, ..., all got noticably better. Especially the highs got much better. Connected together with my JL Audio Fathom F112 subwoofer and DSpeaker Anti-Mode 2.0 DSP my systems consumes 67W average at normal listening levels so a P3 is able to provide more than enough of power (in 230V regions up to 900VA).
