Isolated ground versus self ground outlet

For the outlet recommendation I posted on your other thread recommending Furutech. For a 4 outlet run you can combine a gold plated and rhodium plated…compare them, or run amps off rhodium and source off gold, or the other way around, or even combine different brand duplex outlets…gives you flexibility.

The type of ground was answered.
Now what are you asking? A four outlet receptacle as in a single quadplex type vs. using a pair of duplex outlets? Or running a line and installing a box that allows you to run 4 outlets as opposed to running a single or a duplex?
Lost here in all the ambiguity…
