Good outlet for amplifiers

I have a circuit in my listening room for my amplifiers and it uses a dedicated ground.

Dedicated ground ??? Are your present outlets IG, (Isolated Ground) duplex outlets?

.

The PS Audio power port Classic is good sounding, great clamping force and very reasonable $

@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!

I have worked in dozens of hospitals over five decades and have never seen upside down plugs with the ground pin on top. That includes in operating rooms where a spark, especially back in the day, could be disastrous.
