I would suggest here that the big crowbar issue for a few contributors is 'Whats in the box and how does it work?' which a genuine question. Humans are inquisitive by our very nature especially with unknown parameters.
Let's take Coke a cola for an example, its been around for 125 years, and many companies still try and copy / replicate its formula, oddly (you may feel) is that Coke a cola has no patent attached to it (neither does Lee and Perrins Worcestershire sauce). Simply as in any patent you have to list the ingredients and method of manufacturing special processes, construction method-logy etc for the patent to be granted. Which is why both of these are locked away in very secure secrete locations.
So forgive me why I am not prepared to divulge the whole process to the public after much research/design/construction/material manufacturing and near misses, not to mention time and outlay.
There are quite a few grounding boxes which are on, or have been on the market for around six years now, it is not a new premise by any means. They are a few different methodologies that are circulating Piezo electric type of mineral absorption, capacitor networks, bus bar connectivity etc.
Having tried pretty much 90% of them, I feel that pretty much all do what they say on the tin to a greater or lesser degree. You pays you money and makes your choice if your choice is the grounding block route.
Oli's point is also a valid one, in which he cited for his system that speakers would be where I would be looking to update next absolutely agree 100%. As I have stated before these grounding boxes are not magic bullets, they can deliver the possibility of improving what you already have already, if the system is not balanced (By that I mean even handed, not balanced connections) which can be at any level, not just 'Well tasty'
Steve opted form the top of range version due to the amount connections he physically has in his systems, others will not require such connectivity therefore other products can be used whilst still giving the possibility of system improvement. Customers are very happily using the first model in the series with systems around the £5000 mark, which is if you think about is a realistic amount given that forum contributors buy/sell/swap their equipment over a period of time to build up their gains within their systems. IMHO
Now Jules made a valid point, the SGS box is decent enough to get you on the ladder product, it is very obtainable and for those wishing to explore this option also you can fabricate your own cables as well if you do not wish to choose a manufacturers product cabling. 'No cigar box filled with cat litter or similar' there.
It is also nice to see seasoned debate on this thread with it descending into the abyss of null point!

I think most people who dislike silver over copper are getting confused with silver plated copper, rather than solid silver,,, solid silver cables when terminated properly do not IMHO sound course or bright etc.
The problem in my experience has always been when you mix the two metals, usualy silver over copper, if you understand how signals travel through the cable, it is quite easy to understand why you may experience this mismatch in frequency extremes.

I have some of these bi-wire cables purchased about 20+ years ago, https://www.hifix.co.uk/monitor-audi...-speaker-cablethey are slightly different in that the center between the two wire is blue, but are essentially the same style. The ones I have are Monitor Power Silver 4mm multi-strand, I think they are no longer made. They were pretty expensive at the time 4 6m runs costing about £320, so you could probably at least double that now. Anyway they do work quite well, they give a detailed rendition, with a slight top end emphasis, so careful matching is needed with speakers.
Listening is the act of aural discrimination and dissemination of sound, and accepting you get it wrong sometimes.

I agree it is unreasonable to ask for the secret formula. However I think it is reasonable to ask for some measurements though. That would not give anything away as to how it works but it would demonstrate that it does work to those of us who are aware that it can be unwise to place all our faith in sighted listening tests, whether they are our own or someone else's.

Yup, and notwithstanding Tony's amenable input and understandable position here on this matter, that's also how I see things - but *only* if any measurements taken are valid, and seek to prove (or disprove) the claimed beneficial effect of this grounding box, or for that matter, even help explain it.
I'm not into 'wanking over measurements', just for measurement's sake. Or simply to appease someone's scientific belief system. In that respect, a few meaningless graphs or numbers won't further the debate. The *right* measurements are required, so that they can help identify and explain the phenomenon.
So.... What do you propose is measured, and how?
