Good outlet for amplifiers

@erik_squires Are you saying that the issue is the plug rather than the receptacle?  I've got good power cords (e.g. Shunyata Alpha) and they are not tightly gripped.  Thanks.

@jea48 That's the word I was looking for.  "Isolated Ground".  Thank you! Can any/all of the recommendations above be wired as isolated ground?  I think this is the case if one uses a plastic box for the outlets, or uses plastic washers and screws to attach to a metal box.  Agreed???

@ghdprentice Does this have lugs on both sides, so I can connect through it to a second duplex?  I was thinking I'd get a Furutech for my amps and a lesser unit for the subs.

AND THANK YOU ALL WHO HAVE CONTRIBUTED!

It looks like the furutech cannot be daisychained. I see strapping for a ground lug only on one side. So I’m looking for a good outlet that can be daisychained as I have two duplexes in the same box.

@pinball101 Wouldnt I get a better connection, at least to the first outlet, by going directly into the outlet rather than creating a pigtail in the box? That’s what I was thinking and why I would Daisy chain. Because the most important outlet will be the first one where the two amplifiers are set  also, this quad installation is the end of a circuit… So I’m not too worried about other outlets further downstream.

I’m glad to see that I can Daisy chain.  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? I think I have a metal box… Because the cable is armored and therefore the metal box and armored cable all provide shielding together.

@gdaddy1 I hear you… But I would also have to construct my own cables in that case. I’m using power cables that have plugs on them.

@jea48 Thanks for your attention.  Yes, as you described, there is a green insulated wire included in the run.  I will need to open things up to see if there is also a bare copper wire for grounding the box and to confirm that the box is metal... but I know we used an armored cable running on the outside of the wall to get this additional dedicated circuit to my amps, and so the armor on the cable acts as further shielding/ground, but is not the same as the green wire (isolated) ground. 

When I bought the house, the home grounding went to a water pipe, but the electrician added a outdoor rod. Unfortunately, I am convinced that the rod is sunk just in loose sandy soils rather than moist clayey soils, and I may look into relocating it to something with better grounding properties.

I appreciate your input - feel free to offer more.  If I buy the Furutech and want to maintain the isolated ground, I would need to snap off the metal strap that connects the ground lug to the mounting plate.  I assume this is doable???

I think this is the armored cable used.
