Didn't know. New for me. Grounding for me has alway been power. Thanks for the infoI think this is not dissimilar from Entreq and any number of other grounding solutions that provide options for spkrs grounding.
They also have to be specifically connected to -ve terminal alone.
Looks like a pretty bog standard list of audiophile traits.From their website:
What improvements can you expect:
- Clean, natural sound with a beautiful stereo image.
- Increased dynamics due to reduced background noise.
- Music is perceived as more natural.
- Even less-than-perfect recordings can pleasantly surprise.
- Spatiality increases as small details are better perceived.
- Bass reproduction sounds very natural.
Really? Sorry to be so blunt, but that sounds like complete BS.
And then "The efficacy of our products has been demonstrated through measurement." I'd like to see the measurements!

Measurements should appeal to the ASR crowd.

All reviews are very, very, very, subjective. I have no horse is the race but the measurements crowd is really boring and predictable. Order them and give them a spin, nothing like experience.I only mentioned measurements since they claim to have them, but don't publish them.
Check out the 6Moons review which basically concludes that they have no effect:

Of course, Ebaen explains this "dud" by the fact that his system must already be optimized.

Smells like cheese to me. Love people who disparage a product and never even giving it a real sniff.Thanks for the nice comment.
I don't consider myself part of a "measurement crowd", but this smells like snake oil.

Did you ever try one? Do you own a system that it would benefit from a grounding box? As my father told me once and only once, you either know or you don’t know, if you don’t then seek to find out and educate yourself, otherwise keep your yap shut as there is no debate.This reminds me of discussions about Entreq grounding boxes. Many audiophiles use them, and swear that they do change the sound. But they don't actually offer any "grounding" (there is no connection to earth). So how do they work? Well, one hypothesis is that they actually work as antennas that introduce noise into your system! You could argue that as long as you enjoy the results, the technical explanations are irrelevant. I am always curious to understand.
Okay sure. Either you know or you don’t. Try them or don’t, time to move on.You could not have made things clearer
I would imagine the results would vary depending on the magnetic radiation of the speaker. But not all will need this as some amps would cancel that high frequency noise so the speakers don't radiate it. There are frequencies above 50Khz that if it leaks into the crossover, the capacitors esr aspect of them becomes inductive and as a result, lowers the efficiency in the circuit. As someone who designed classic tube amplifier circuits, I look at this, especially when the output transformer ends up having a lot of insertion loss and the plates have excessive RF tube noise..From their website:
