Love the detailed [read "very helpful how-to"] photos, Serge. And a great look with the grey cover plate.

Also revisiting this thread with regard to the weight of the outlets I have on hand, just for the heck of it.

Pictured is a Furutech GTX-D NCF(R), Shunyata SR-Z1 and a lowly Leviton. Last picture is the Shunyata CopperCONN as a reference. Off course all are 20A rated.

The SR-Z1 is the heavy weight champion at 112g, next is the GTX-D NCF(R) at 108g, then the CopperCONN at 94g and finally the Leviton at 60g. Surprising that the SR-Z1 is about twice as heavy as the standard Leviton.

I would argue that there is a continuum going from

Furutech GTX Gold plated to Furutech GTX Rhodium plated (NCF) with CopperConn in the middle. I find Rhodium to be: Positive-transparent, detailed vs Negative:too sharp, brittle. Gold-plated is warmer, musical, bloomy on the bottom, less detailed. CopperConn is sort of between the Rhodim-Gold Poles. No matter what people say ("neutral, neutral, neutral") I think we all find a desire to tweak our systems towards one or the other direction depending on where it is or what recordings we like. Having jumped between Rhodium and Gold at times, the middle can be welcome too. YMMV.
Thanks for your input. I had the plan to install the Furutech GTX-D NCF(R) to compare to the CopperCONN but after reading your post I decided to leave it as it is. You pretty much answered the questions I had. And frankly, I am so satisfied with the CopperCONN that I don't want to touch anything..

I had some extra time this morning so I jumped on this golden opportunity to install the first CopperCONN outlet. As I have previously said in my initial post, I installed only the one feeding my amplifier and source as I am just replacing the SR-Z1 for now to isolate the audio benefits of the CopperCONN, and in order to have a proper basis for comparison.

So I started to remove the SR-71 which you can see side by side with the CopperCONN for comparison. I took the extra time to cut the end of each wire and also the ground, which I also cleaned with some sandpaper (there was some leftover paint on it). I realized that I had installed the SR-Z1 wrong by wrapping the wires around the screws like you do with the standard outlets. So by cutting and stripping the wires with the proper clearance (which is shown at the back of the CopperCONN, approx. 1/2"), I inserted the wires the proper way by the back of the outlet. One thing of notice, unlike the SR-Z1 which is compatible with Robertson heads, the screws on the CopperCONN was Philipps only. No big deal but for us in Canada we use Robertson heads screws for about anything. Speaking about screws, I think it would have been nice to have two screws included to secure the outlet to the electrical box. I had to salvage the ones I was using for the previous oultet. Anyway, no big deal but some competitors offer this. Once installed, I turned on the breaker back up and (fortunately) there was no *POOF* so all was good .

I won't do any justice to this magnificent product since I am on the first hours of listening but what I can say right off the bat is that it is significantly better than the SR-Z1. If I relate to price alone, I think the CopperCONN is justifically priced in reference to its performance compared to the SR-Z1. The SR-Z1 is 100$ while the CopperCONN is 295$ and I think it matches equally the performance gap between both. Quite an assertion it does sound like it.

I will post the comments of user Mobiusman about the CopperCONN over What's Best Forum, which I find to match what I can hear so far:

"...much deeper bass with more authority, better percusion and much more realistic and musical sounds throughout. The imaging is already much deeper front and back..."

Please remember that I only changed one outlet. I know that if I had changed both outlets at the same time, the results would have been even more impressive. But for the sake of analysis I chose to change only one. Anyway, to install the second one, I will have to install another electrical box 32 inches away as the other one is too far (and since two is not enough).

So for me, I think I found the holy grail in audiograde outlets. It turns out just to be everything I was hoping for. And this is not even broken in. It has all the quality I like about the cruzeFIRST Maestro I had last year and expand above and beyond. The Maestro is an excellent outlet but it was lacking that tiny bit of bass slam that I like. But to be fair, at 89$ the Maestro is a steal for what it does.

I will report back again later but for now I will just listen even more. Kudos to Caelin for such an amazing outlet.
Nice write up. I'll need to grab one. BTW in the hospitals we install outlets upside down so the straight ground pin can prevent connection loosening. Much better physical connection. Not sure with all these heavy cables why power conditioners etc, are not designed like this.

I orient all of the outlets with dedicated circuits in my listening rooms in this manner.

My house was built in 1983 and in those years the ground pin on electrical outlets was oriented 270º. But now in today's code it's like you describe.
