I could not resist and I installed the second one tonight. This one is feeding my Bryston BDA-3 only (along TV box and Chromecast). The first thing that struck me after the installation of the second CopperCONN is the scary increase of detail in the music. With the first CopperCONN outlet, the thing that struck me first was that the music was more "there", more forward than what I was used to. I realised that this was probably a thick layer of haze that was removed from the music. But with the second one, the poor 3$ Leviton is completely obliterated. With my reference material like Ballagusto from Adam Ben Ezra, I could hear details I have never heard coming from the back of the stage. All this was hidden not by a layer of haze, but a thick fog. The music sound supremely more precise, especially on acoustic stuff. Truly what this outlet is doing to the music is remarkable.

For those who will go straight from standard household electrical outlets to the CopperCONN, prepare to be wowed. Honestly, the increase in performance is like a huge power cable upgrade, or fuse upgrade. From a price to performance ratio, the performance they bring far outweight their initial cost. Frankly, it makes no sense to invest a large sum of cash in a sound system which is only to be fed by 1$ outlets. From my experience, it starts with the outlet or at least, the outlet is an essential part of the audio chain. Knowing that I got the outlets right, I can build from there and for me that's a relief.

Great review, Serge!

I'll also add that many of the attributes you describe become even more fully presented/embodied with the Denali or Everest PDs. I'm listening to some complex classical music right now, and I can pick out the finest and most subtle details of a fairly low dynamic range instrument (a classical Spanish guitar) against the power and complexity of a full orchestra. There a weight and body to the orchestra that is ample and rich but you can still follow the subtlety and nuance of the continuo in the lower octaves.
