Grounding boxes - The real deal

[Mr. C]

Hi Jason

RF as Alan mentioned is very pervasive and particulaly elusive if you are trying to locate / pin down a particular issue you know is relevant.

Ive just used one of these to galvanically isolate my hifi network from the modem and in power extenders and the sound quality improvements are significant. Comparable to some of benefits described by people using grounding solutions potentially.

i have essentially eliminated a ground loop in the communication network.

My soundstage is wider, taller and most noticeably much deeper. Music is also more relaxed , open and natural sounding.

I borrowed this from a friend and I grounded the strap to my power hub earth point with 1m of 5 strand solid silver litz that i initially bought for a DIY entreq style ground box.

Good stuff Martin
Seems to be US centric
How much did you pay and where did you get it ?

Do you have any other mains devices around like ferrite chokes, filters or other ?

Yes. The original principles were laid down by Professor Stanley Unwin in the late nineteen fiftes. Every subsequent interpretation has been based on his model.

good old Stan. He was in one of the Carry ons

The network transformer is likely to be 10 years old , they have been sat in a control systems engineers drawer for 10 years at work. The model i have is the 570 but i see some 580 ones on US ebay with starting from 10$.

The guy on the AV forum who put me on to this linked this offering from RS https://uk.rs-online.com/web/p/signa...oning/7511392/

I didnt want to splash out £150 on the off chance , however with the results ive got I absolutely would spend 150 on this, its probably raised my systems performance by at least 10%

I dont run any ferrites , i picked up an old Russ Andrews ultrapurifier about 6 months ago that sits in the same power strip, passively.

I have a few upgraded power cables in the system, all picked up second hand , a couple of which I can see components in the plugs but ive no idea what they are or if they even still work.

Trust me, horizontal or vertical orientation makes no difference to surface area.
Your chosen installation method did that. You could have done the same thing vertically, but it would have been much harder, and more expensive.

Obviously there will no change to the contact surface area between the rods and the soil, but the efficacy of the earthing system will depend on orientation, depending of the variation of soil conductivity with depth. It cannot be assumed that the conductivity will automatically increase with depth: it depends on the composition of the soil, whether there is a rock layer under a shallow depth of soil, etc.

I worked in radar and microwave research for thirty years and can tell you that there are a whole variety of earth electrode geometries and configurations that can be used depending on the environment where the system will be installed, and each have different and frequency dependant complex impedance. At ultra high frequencies often the inductance of the earth system is more important than the resistance.
