I have met the owner of Puritan ( Mike ) many times really nice guy and honest, great products.

In UK, the "plug in" version does not seem to be supplied so why I have posted a link to Russ Andrews who make other products.

I tried an earth wire 10 mm one wire connected to a Power supply for a DAC then in to a ground rod as an experiment FOR A FEW MINUTES ONLY.

DO NOT CONEECT ANY OF your equipment to a ground rod without a RF router of some type.

Moving on.

Grounding my system with one wire via a ground rod as above made a pleasant surprise, bass improved and treble less harsh so went all in for a full blown system with 2 x 3 meter ground rods 21 metres apart with 16 mm earth cable.

One rod measured 18 ohms two rods 10 ohms.

I must admit there was not much more improvement with the full blown version that ended up being quite expensive various cables and all equipment connected.

My advice is try a ground rod with one wire before you purchase a RF Router.

Hope the above helps......

@ozzy The plug going into the socket provides the ground.  The green wire connects the unit to the Routemaster, which provides a number of connections for grounding all of the components in the system (see photo with different terminations of those other green wires).

twoleftears,

So, the Groundmaster City costs $250 and cannot be used without the other device the Routemaster that costs $700. Is that correct? Why not sell them as a set?

It also seems that it should be able to be plugged into a Entreq that has 4 connections.

Just talked to a rep from Puritan. He advised against using the Puritan Grandmaster City version to connect up to my Entreq.

@ozzy or anyone else experimenting with ground boxes.  Have you been able to confirm whether or not you gain SQ improvement by:

- using silver wire vs. copper

- solid wire vs stranded

- different gauge size

- cable lengths matter

- connector end metal types or just nude

I tried using nps 1260 and didn’t distinguish any additional improvement. Thanks
