May be bs to most, but listening is believing.
But oddly enough, the belief that "listening is believing," combined with the nature of human perception, is precisely what allows all manner of BS to find a market. Because of this, there is literally nothing too absurd, nor anything which does not "work" for some number of people. Up to and including putting photographs of themselves in their freezers causing their audio systems to sound better.
So what is really being said when one says "listening is believing"? If listening is believing, may we also say that seeing is believing?
Upon seeing this:

One may well be led to believe that A and B are the opposite ends of a straight line passing through the black rectangle. However a straightedge reveals this to not be the case.
So again, what is really being said when one says "listening is believing"?
I used 2 of them in my system to ground my dac and preamp and it works better than most other tweaks.
Your DAC and preamp are no more "grounded" than they were before. After reading Acoustic Revive's "explanation" of the thing, it's pretty clear that they haven't any understanding at all of either basic physics or even the concept of "ground." It's as if they're working off some grossly oversimplified, grade school notion of what "ground" is.
Acoustic Revive is very famous in Japan for being an audio company that only specialize in accessories that consistently win annual awards at the local audio awards.
So? The only reason for such awards is to impress people who are impressed by "awards." It's otherwise known as "marketing."

The Japanese are serious at tweaking and certainly have better gadgets than any in the west
And only in this industry can those who haven't the foggiest idea what they're doing, often times just making stuff up out of thin air, consistently come up with these "amazing" tweaks. That in itself is truly... amazing.
