Hi all.

Just interested in these grounding boxes... not sure if they are total foo.

But the prices are astronomically high so I wondered if anyone had made any which they think work?

Thanks

I put Alan's (one of the coherent ones) in my system and the sound stage collapsed.

Had a totally negative effect in my system, yet appears to make a good contribution to his system.

50/50 in my opinion.

There was a massive thread on AoS about them not that long ago.

Yup. It was proved that nobody can prove what it does, if anything!

I bought some bits for this, cigar box, copper plate and wire, some rca plugs and some litz silver wire. Got derailed researching the minerals and then i used the litz for an earth strap on a network switch instead.

Tourmaline quartz and rochelle salt are 3 of the minerals in his box. The minerals donít come cheap and its hard to guess amounts.

Happy to sell on bits if anyone fancies taking it the whole way.

Aahh.. Yes... LOL - I forgot about that EPIC thread.

They do seem to be getting more popular since I first looked years ago.

imo Itís a load of cobblersCan't be Cobblers because it did do something in two different systems.

Trouble is you don't know what it's gonna do without sticking one In and they are far too pricey for that sort of gamble IMO

It does something BUT that something is unpredictable.

Yep and there are other systems where it did bugger all, like I said it’s MY opinion, if you think otherwise that’s fine but please don’t waste your time trying to convince me.

Just saying that it does have an effect, not sure whether it would be desirable or not.

Have you tried one?

I think it must be a synergy thing too.

They are extortionate price wise. The people who have them like them and justify and defend their purchases with vigor.

Can't argue with that. However, because of the expensive nature it would be good for one of the companies to offer a free trial of these units.

One time I visited Tony at Coherant and he demonstrated his groundboxes. Noticeable difference. He switched between a groundbox inline and offline (but blind to me) and I was able to guess which was which.

Sadly he had no demo units I could play with at home and I was not up to springing for buying one.

Seems a shame.

The difference you experienced must have been pretty profound. Would. You say that?

Profound implies something profound - I would say subtle but noticeable. A greater ease to the flow of music, a more refined inner detail. Stuff like that.

I don't think Tony was reluctant to lend me one due to prices, simply that he had many orders. He did lend me a class d amp for quite a while. The amp costs a multiple of his grounding box. I wrote about the class d amp somewhere here.

If I recall they are a box full of charcole and cost a fortune , I think its a Rip off ( Snake oil ) product :)

Possibly a way to test the water (for those that are interested) . . . .

As has been mentioned "can" do something in "some" systems. I like the idea of tweaks like this but also understand the skepticism regarding a box of stones of varying sizes.

If you're firmly in the digital is digital/power is power camp this kind of product will undoubtedly wind you up but I for one won't knock until tried!

Spades being spades after all.

I pick up a Entreq Minimus with cable for a song with a view to flipping it. Gave it a go; I have to say in my system it works. Sonically it changes little probably less perceptible bass, but I think this is due to the absence of background noise. Individual voices and instruments have more space, height. The soundstage is now extremely wide. When sat off access, some tracks the may sound very thin, however very good in the sweet spot. It took about three weeks to fully appreciate it effects, which I find subtle. It's when I removed it from the system there is a noticeable presence of grain and congestion which is acceptable at my budget, but not anymorel. Would I recommend it? not really but it is worth a try if you live in a highly populated location and appreciate music sounding freeded from the speakers. My grounding box will be staying put.

To conclude, IMHO its effectiveness has more to do with the plugged in equipment's environment than the box itself. Hence their controversy nature. https://uploads.tapatalk-cdn.com/20190811/04ea800dd917e4313f3a84804d1b3b36.jpg

Barrington , may i ask what the rest of your system is ?

Did you experiment with what components you connected to it? As i think you can only add 1 piece of kit to the minimus.

Thanks

My equipment is Densen B100 and DM30 Bi-Amped out to a pair of Ushers Standmounts/Tannoy T200 Super Tweeters, with a custom built turntable and phono stage as the front end. The B100 acts as the earthing point to which the phono stage is tethered. Then just spade to spade from the B100 to the Entreq.
