I'm not doubting you either, it is just the lack of information, explanation and science from the manufacturer is what is throwing up the red flags and doubts.
Oh, BTW, I did search youtube for Nirvana Audio Chronos and found 4 videos. 3 were in Chinese. The forth was a before/after music only, which isn't reliablable. (Sounds like it was recorded by a cell phone.) If you could post the link to the video you found, it would be great. All you have to do is play the video, copy the link in the address bar of the browser, and then post it here.
