Power Plant Premier making sound worse?


I have 2 new dedicated lines installed using Telsaplex outlets. I have 3 Kubala-sosna Emotion PCs feeding an Ayre V5Xe, Ayre K5xe and Ayre C7xe. They were all plugged into the PPP, a Lossless PC feeds the PPP from one of the dedicated lines. I noticed a buzzing sound that went away from the PPP so out of concern I shut off the PPP and fed all the Ayre stuff to the outlets directly (amp to one outlet, preamp and CD player to other) via all KS PCs. It sounds much better, more texture and detail. I am very surprised so I am not sure if there is an issue with the PPP or should I just get rid of it? Please comment

I had a PPP for a bit in my system and it did what most of the conditioners I have owned (Isoclean, Sound Application) or demoed (Hydra V8) did, it sucked the punch and liveliness from the music. It just softened everything.

However, I did demo a PurePower 1050 for a few days. This is when I discovered how much the Isoclean was not right for my system. The dynamics and punch came back when I used the PurePower. The dealer did not let me demo it long enough to develop a thorough opinion and the fan in it was a deal breaker for me. And the form factor was also an issue. However, I am still considering getting one.
Drubin, in a well-adjusted high end system, the difference between pure copper, gold and nickel plated outlets is abysmal.
I write from experience, because I have four outlets behind my system and can easily test/demo the differences.
Nickel adds a metalic sheen to the upper midrange and treble. Once I hear it, my brain locks on it and all the fun is gone. Think early CD players, that's the kind of effect I hear.

BTW i prefer pure copper, silver and gold plated outlets. I have not enjoyed any experiments with rhodium-plated outlets, but that is one person's taste.
Casouza, I second your opinion of nickel plated outlets (and IEC inlets as well). I've replaced every stock nickel plated inlet in my components. I don't get why all high end manufacturers put some of the finest caps, resistors, and what have you in their equipment, yet install a crappy $1.29 inlet ?
When I tried the Emotion Power cords, I thought they made evrything sound way too dark, with a great dampening of the treble.
Others claim the Emotion cables are great! Well they did not work very good with my gear.

Perhaps the PP is having the same issue with the Emotion cords.
