Puritan PSM 156 connecting Puritan Grounding Products?

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.

@jea48 during your reading you've missed some critical points.
The Puritan GroundMaster is not directly connected to the safety earth and has no bearing on that.
Also, it deliberately provides isolation against low (power) frequencies as a safety measure.

What it does do is by virtue of its, "12 Individual Alternately Tuned Frequency Guides" provide a low impedance independent path to ground (via copper wire ;) for electrical noise.

It is very effective.

I have the ground master and the pms-156. I want to ground only 2 units. Must I buy the route master or can I get away with running the two through the ground master?
