Having tried and noted that the Quantum Resonance products seem to work, even though I have never gotten a real explanation as to how, I feel compelled, as a wide eyed optimist as it relates to audio improvements to respond.
Imagine trying to explain (though they haven't yet tried to prove in any notable scientific manner how this works) the broadcast of a radio transmission, back in the middle ages--even x-ray technology to those not yet exposed (no pun here).
There are many more things beheld by us yet not understood or quantified by our current level of understanding or interpretation of physics. Hell, we're still working on 'dark matter' string theory and 11 diminsions.(For that matter, at this seemingly late date, we, about 75 years after discovering Pluto, find it's mate just beyond-- what makes us have the audacity to presume that we can understand what these items do, or don't do?
What if it works and even those who made it don't fully understand why?
Supposedly, the person who designed the Quantum product, refuses to openly discuss why it works, presumably for proprietary reasons. I was told that his background is in Biomed--and that he is capable of turning a dead, fetid pool of scum on a farm, into a thriving ecosystem with some of his other work. True? I don't know. Stories always seem to surround people like this with no full explanation.
The solution here is a 'blind' A/B. Why not a challenge of listeners to quantify this device--if it works, who wouldn't purchase this kind of improvement for $200.?
I would-- so, how about a challenge?
Anybody game? Especially those selling it--we all WANT to believe, give us a reason, not just compelling side statements.
