Pal, do you get an increase in voltage once it goes through the ZLC as well?

Oh.  I can't see the meter on the back of my ZLC but I think I'm fortunate and have fairly steady power.  There are some advantages to being part of a rural electric coop I guess.

Could be.  My transformer is in my front yard and I'm the end of that line.  I have a voltage readout on my meter which seems very steady.  What I don't have is a meter that I can check my outlets.

ARGH! That is not supposed to happen, and doesn't happen with mine.

I'll call Decware on Monday and report my ZLC. I'm sure it's just one of those things. I certainly was not intending to cast a shadow on the Decware team. The rest of my Decware is fabulous and I can't imagine listening without my ZMA.25, CP3.25, ZP3.25. etc. I was a little hesitant to reach out right away to Steve, I know they are slammed. I wanted to make sure I wasn't having a "stupid moment" with the ZLC before I called. My ZLC has really made a positive difference with my setup. Thanks for the comments

Over the weekend and yesterday I played around once again with adding the ZLC to my main system. I used the exact same power cord for both the ZLC and the PS Audio Power Plant P10 so that variable was eliminated as a factor.

As I had issues using it to power the PS Audio Power Plant P10 and then the rest of the system before (it seemed to add a few percents of increased voltage for some reason, or at least that is what the P10 tells me) I instead first tried using the ZLC to power all the analog components and the P10 to power all the digital. I was able to let it all simmer overnight and listened for a few hours late on Saturday. The sound was different, can't say I preferred it. It seemed a bit tighter, drier, brighter than my default (P10 powering all components). There also seemed a bit less depth to the soundstage, everything pushed forward a bit more. I played with the modes and settings on the P10 but little ameliorated that.

So before retiring I reversed the set up with all my analog components powered by the P10 and the ZLC powering all my digital components. Then I let all simmer overnight and revisited the system late on Sunday. This was a better configuration, bringing me closer to the sound that I had before with some differences. Playing with the settings on the P10 had a happier benefit on the analog components than the digital. I was able to regain that depth of soundstage, and much of the tightness, brightness and dryness to the overall sound dissipated. I left that configuration in place and listened with that setup through yesterday afternoon and got a handle on the sound and enjoyed it with a lot of material, but I missed a certain warmth and "ease" that I felt was there when all components were powered by the P10.

So yesterday evening I removed the ZLC from the system and restored all components to the outlets on the P10 and let it all simmer and I have to say, today. . . I eased into the restored familiar sound and noticed better bass and better dynamics as well as a smooth ease to the sound. So I've put the ZLC back into my least used system, the headphone system, and think I've done due diligence and I'll let it do its good work there.

I wish I could quit tinkering with the setup and just kick back and enjoy the music. . . . I do do that for long stretches but reading here fires up my imagination and I do enjoy the experimentation, especially when it bears new fruit or ratifies my previous choices. This is such an involving hobby if you let it be so.

Well, I'll note that I got the P10 brand new at the lowest official price I've seen for a new one, about 60 percent of the listed price you quote.

And yes, I find it significantly better. I'd not want to be without it. What I can do with the P10 as far as tuning and tweaking is really amazing to me.

The ZLC is great for my headphone only system, a system that I allow myself to have lowered expectations for and that I don't use as frequently. I'm glad I have it. But it's my third favorite of three electrical components I have: the P10, the Power Plant Premier, and the ZLC.

Do you even need to plug in your ZMC1?  I don't plug mine in.  I think the plug is more for a ground issue -- the manual talks about this.  The ZMC1 doesn't use any power.
