Why not use the ground master city. It just plugs into your outlet and connects to the PMS 156. It was intended to be used without an outside grounding rod.
Puritan PSM 156 connecting Puritan Grounding Products?
I've recently added the Puritan Audio Labs PSM 156 to my system, which has been great. There's already a lot of praise heaped on this product, so I won't add to it, other than to say, I'm so impressed, I'm looking at PAL's Grounding Products just to complete the circle so to speak.
My initial thoughts are the GroundMaster, coupled with the GoundMaster City (no inclination to attempt driving an 8ft copper rod through my garden soil).
So my question is, what would be the connection flow for this? I could be way off, but my thinking is:
Groundmaster connected to PSM 156 - Groundmaster connected to GM City.
Is this the way it would work, or would I kill myself 😂?
I can't seem to find much on actually connecting these products
Thanks in advance 👍

Conduct the chase with a professional. I made the complete run with someone smarter than me, Tom at Big Ear Stereo in Tempe. He gave great insight into all of the Puritan products and the why and how of each one. I even grounded all of my components to include my ATC towers (active).
Yeah, it's a rabbit hole, but there is a very nice bright carrot at the end. Each piece added, or in this case subtracted, for improvement of the system.
He even screamed at me, correctly so, about my Netgear meta data transfer. Anything to clear frequency nasties from the chain. I got rid of it.
I do not have any personal experience with Puritan PSM Grounding products. I do have experience, as well knowledge, with the use of dedicated, isolated, earth driven ground rods though. They do not do what, some say, they are said to do...
Does the NEC, (National Electrical Code), allow them? Yes...
There is no requirement for the size of the ground wire used from the ground rod to the connection of the branch circuit EGC, (Equipment Grounding Conductor). Example a #24awg copper wire could be used.
Exception, but the earth shall not used as an effective ground-fault current path as specified in 250.4(B)(4). Therein, the branch circuit EGC cannot be lifted, disconnected..

In the first part of the video the guy has no idea what he is talking about. EMI is not diverted, drained, to Mother Earth. The Earth does not possess some magical mystical that will suck nasties from an audio system. Circuits work in loops. If EMI is connected to the earth there must be a current path for it to return to the source.
Another problem with the guy’s explanation, theory. A ground rod is not directional. It’s a two way street... In other words the rod does not prevent EMI traveling in the earth from entering through the rod and dump EMI onto the audio equipment chassis, metal enclosure. There’s a very good chance it will.
A dedicated, isolated, ground rod is also a good path for a high voltage lightning transient, caused by a near by lightning strike to earth, to enter through the rod and fry audio equipment as it finds its way back to Earth on the branch circuit EGC as well neutral conductor, (The high voltage transient will bounce around inside a piece of audio equipment jumping across to the neutral conductor), at the service equipment where the service neutral and EGC are bonded together and then connected to Mother Earth. And remember it is a two way street.
My advice would be to use the GoundMaster City...
