Grounding of system

[TBG]

Hi all,

I have been following the threads about Entreq and Troy grounding boxes and wondered whether my system would benefit from chassis and signal grounding in this way. Instead of buying one of these boxes, I was considering installing a copper grounding rod into the earth outside my listening room and then star earthing all the components to that. Is this worth doing in your opinion and will the benefits be of the same magnitude than what could be achieved via a dedicated box?

Many thanks,

Bill

Sorry to have been so long in responding. There are really three issues in your posting. The issue of the Earth ground has nothing to do with Entreq. Your ac outlets ground to the Earth. And yes they are a very great improvement in my experience, but note you have to have good moisture in the soil around the grounding rod. If you live in a arid area, you will hear no benefit unless you have a spring nearby or the drip from an air conditione, etc.

The Tripoint Troy Signature does connect to the ac system and thus to Earth. I have no experience with it and top notch Earth ground but expect it would benefit from it.

The Tripoint can be used to ground signal as well as components. With three binding posts, choose one for signal grounding and use the other two for component grounding, but you must use a slide on RCA to get only signal grounding.

The Entreq units that I have seen, only ground the signal to materials in the box.

The connection to Mother Earth has nothing to do with normal day-to-day AC power line quality. It's only there for safety during unusual circumstances.
What is important is that the Safety Ground/Protective Earth make a good connection to the Neutral at the main breaker box/service entrance.

I know that Entreq maintains this, but I tend to find that misleading, because more often than not, signal ground is tied to chassis ground. A simple measurement will confirm this.

You don't need fancy equipment to ground your system.

You need to ground every single component (a wire screwed to the chassis) to ONE (1) single ground point.

Star grounding (bonding) all the components is the key.

Exactly CORRECT.

Hi how does one ensure only one ground if, like me, I want to keep my components plugged into a re generator as my voltage fluctuates, but want to plug my power amps directly into the wall. So is it a common ground since both the re generator and amps are directly into the wall?

 

[Speedskater]

Are the re-generator and the wall outlets on the same circuit?

Yes

Yes

That should work fine... but even better if you have a power distribution block for the amps next to the regen with their chassis tied together with a heavy ground wire.

Gee, another CORRECT answer.

The only issue being that not all manufacturers understand grounding, so even with your best efforts a ground loop can still result. Funny thing is, if the equipment has a properly designed ground plane, the external grounding scheme won't matter very much so long as it is grounded.

And another CORRECT answer.

Now some 20 years later, many hi-fi manufactures still haven't heard about the "Pin 1 Problem".
