Grounding boxes - The real deal

[NRG]

Probably the latter, but as I say I don't know.

Heat according to the review posted earlier...oops beaten to it....

[Marco]

What I'm saying is that if whatever it is that has been added is not unpleasant to the ear or below or above your hearing ability, then chances are you'll not know it's been added.

Yes, but what I'm saying is that you may not *truly discover* whether it's "unpleasant to the ear", or otherwise, until after having lived with it for some time, and then removing it and reverting back to what you had before!

Sorry, missed that.
A...

If you actually read the review - link posted in post 269 - it does mention converting the 'noise' into heat

And I'm saying that you might never know if something has been added or taken away, dependent on its subtlety or how pleasurable it is to the ear.
You may determine that something has been taken away from the sound you are hearing, but it could be quite the opposite. This is why measurement could be an eye opener in the case of these grounding boxes.

[Marco]

Agreed. For e.g vinyl adds quite a lot of things that are not supposed to be there but it either doesn't add enough of them to be a real issue...

So does digital; simply in a different way!

Both impart their own intrinsic forms of coloration, to varying degrees. You need to rid yourself of the erroneous notion that digital music reproduction is somehow 'transparent'... It isn't.

I’m waiting with bated breath for comments from others who have tried one rather than discussing the theoretical reasons why they do or don’t alter the sound. I wonder if MikeMusic has a dedicated ring for his equipment or not. Seems like the money to be made comes from the recommended cables. Will a coat hanger wire suffice?

Yes, I agree, but the point is that the effect has to be assessed for and analysed properly, over a period of time, not simply via a quick-fire A/B comparison, or even a lengthy A/B/A one, on the same day at a bake-off...

And measurements are only of any use if you're measuring for the *right* things, in order to correctly prove or disprove an effect, otherwise they're useless. We're not entirely sure how this device works yet, so how would you know what to successfully measure for?

Marco,
You can asses and analyse till the cows come home, but on a piece of music you are familiar with if the differences are huge, then a short A/B should suffice ?
It's all about the music.

Well, the claim is that the box removes RFI. We know now that RFI is across the spectrum so you can't measure all of it but if you can inject RFI into the environment in some band that is measurable, then you can measure it - or the lack of it after use of the grounding box.
You don't necessarily need to know how it works to prove it works, although it'd be nice to know.

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
