Grounding boxes - The real deal

[AJSki2fly]

Hi Julian.



Nope, you have to take some proper steps to (as far as possible) remove any expectation bias.

We're all susceptible to it, especially when in the company of enthusiastic users of the product in question, keen to show off their 'new toy' - and I wouldn't want to be paying £800 for *anything*, until I was 110% convinced that any benefit I heard was a) big enough to justify the outlay in the first place, and b) real

Here you go Marco, this is what I am thinking of doing.

I have a 2 bottle wine box so will order a couple of good binding posts £6 approx, order some pure copper plate about £10-12 cut to size, and order some mixed natural ORE ( I am trying to find a source for this). Assemble and connect to the pieces of equipment you want to try it on to spare RCA inputs on the units, the connection is done to the negative only of the RCA plug (this is the outside that usually connected to the screening of a cable).

I take no responsibility for any weirdness that may occur or anyone wiring up cables incorrectly and damaging equipment.

No conclusion reached, that's why I said 'seem to be needing', just checking

Good, because you should know me by now!

My personal position is simply that, as with *anything* else in audio, cables, mains filters, stands, grounding boxes or whatever... Nothing gets used in my system unless *I* am 100% convinced it does something positive, which *I* consider as being worthwhile and beneficial.

Other people's testimonies on this device and others like it, whilst interesting to read and something I'd always encourage, mean nothing, in the context of *my* system. That's simply how it is

Nice one, Adrian. I look forward to your write-up of the results. When it's ready, please post it in the DIY section.

Sorry, don't know what you're trying to link to, as all I got was the homepage of some hi-fi site, not to anything specific you're discussing...

For all you nay sayers out there all I can say is go and listen to what one can do.

Tony of Coherent Systems graciously responded to my desire to 'hear' one, so I paid him a visit.

They work. Period.

The transformation was astounding, more of everything positive, nothing negative.

More later.

I paid Tony a visit today, mainly to have a listen to his PWM amps (more on that later in the relevant thread), but also to see/listen for myself what these grounding boxes can do. Essentially there is a step change/improvement in SQ. All what has been said applies - improved ability to 'see' into the music, greater definition, more space around the instruments/voices, widened soundstage. To paraphrase Sugden, the music was rescued.

Tony amply demonstrated the effect by disconnecting all cables from the ground box and, leaving preamp levels unchanged, slowly connected one-by-one the various cables (e.g. from the DAC, preamp etc) back to the grounding box. Each step there was an appreciable improvement to the SQ. My ears did not deceive me and even though there was no blind AB (or ABX) testing I feel I'm sufficiently confident of not letting expectation bias creep in.

I don't have sufficient technical knowledge to explain 'why' it is happening. I'll leave that to others to do. However I feel sure there is some good science underlying it and not simply foo.

Thanks Tony for being so generous with your time.

Ah I see it now... Jeez, after witnessing that eyesore, anyone complaining about ads on here should wash their mouths out!

I just tried it and it’s right, if you scroll down you will see pics of the diy grounding box

Yeah I know mate, you just have to plough through reams of shite to get there.

What on earth are you using, time for a
bigger screen, or perhaps you need to turn down the zoom or go to spec savers
