I wasn’t sure that a Power Plant would help my system so I’ve been on the fence about getting one for a while. When the P20 came out I asked Paul to try one and I’m glad I did.
With two people (and the handles on the front and back) it was easy to get into the system. I grabbed some Shunyata Taipan power cords I had around and put the P20 between the wall and my Simaudio W-10 monoblocks. Then I played some music loud to see how much headroom I’d have. A little louder than I’d ever want to listen for any length of time I was at about 60% capacity on the P20 so there’s plenty of extra headroom.
After listening for just a little I was hearing things I never heard before - I know it’s a cliché, but the new things weren’t subtle, instruments I’d never heard in a orchestras (e.g. in just about every cut of “The Film Music of Jerry Goldsmith” Telarc SACD and “Round-up” Telarc SACD) as well as in simpler music.
The second day I moved my EMM Switchman preamp to the P20 as well and did some more listening. Everything has a little more ease, a little more flow, more dynamics, tighter bass, a blacker background which, for example, made it much easier to hear when the reverb on the voice of recordings was different than the reverb on one or more instruments, etc.
But what really matters is that my wife immediately reported similar differences without prompting.
It definitely won’t be returned to PS Audio and will be a welcome addition to my system.
