Good outlet for amplifiers

Hubbel 5362. These come in 15 and 20 amp versions and are better made than typical outlets from Home Depot. They are all copper and are heavier duty than a typical outlet. They are under $15 each on Amazon.

They are not copper, they nickel plated brass. Of course brass is half copper. 

In order to isolate the ground, however, would I break off the tab that wraps around one side of the unit to the ground lug? 

But why the priority for isolated grounds? Why not use Puritan groundmaster instead. Shunyata or nordost have their grounding systems also for much more money. 

@jea48 what are your thoughts on isolated grounds? 

I want it to grip the plugs well. Recommendations?

Grip is one thing, the tendency of the heavy attached power cable falling out is another. Shunyata came out with their cradles for that reason.

Viborg also has one also: Viborg outlet

Beyond the actual grip, because the cheaper brass hospital plugs do this with stronger springs and more metal, there is the issue of damaging the outer layers of metal on the plug on your expensive cable. In theory this would deteriorate the performance.

That is what is wonderful with the Furutech GTX in that its clamping system does not marr the plug end. And it sounds wonderful too.

Best - Furutech GTX-D(G Gold) - The GTX-D(R Rhodium was too bright for me, but it is a detail machine...but took forever to break in)

@vthokie83 

I have the GTX-D Rhodium and did notice it took more than 400 hours. So it was the rhodium that caused the long break in, and not the NCF? The gold broke in with less time? 

@thecarpathian 

It is just the coating that is rhodium in the one described above, the contacts are all copper. You can't have uncoated copper, unless you want to clean the corrosion off weekly. 

Viborg VM02

@vthokie83 

I'm not sure what caused the long break in to be honest, I just know the Rhodium took me over 3 months.....not sure of the total hours. I was working with 8 (9?) receptacles for about 13 months. I also tend to prefer gold plated, then silver plated, then rhodium plated in that order

The GTX-D(G) took about 6 or so weeks

Thanks, sounds like it is the rhodium then. 

Just received a Viborg rhodium outlet, and I'm debating putting in on the freezer in the garage for a month instead of into the hifi system. One hand it is interesting to hear the changes, but 400 hours again; even listening for 12 hours a day that is 33 days. Think after just doing that math I have decided the former. 

@thecarpathian

Maybe it’s applied in such a thin coat it’s conductivity isn’t so much an issue.

That is my understanding, but then why does it sound the way it does? How can a few microns of a coating make a difference to the sound? No idea, but it does. Cardas and all those other plug, connector and cable companies must have had some reason to use it over brass/silver/gold. Caelin Gabriel is the only guy who has stated he didn’t like rhodium to my knowledge, and does not use it in his stuff.

...on the all copper is your attaching bare copper wires to it anyway some decades old

You know, I’ve never thought of that. It never occurred to me to clean the ends of the wire with some emery cloth. Obviously I don’t think the most anal and eccentric audiophile would do this on a regular basis, but yeah, if you’re installing the plug it would be a good idea- why not? I am sure some audiophiles use some deoxit there.

And silver tarnishes too, don't forget.
