Quantum Products Symphony Pro


I was first introduced to this product at 2006 CES, where they installed in my listening room for a few days. I noticed an immediate improvement in the sound quality. More smooth and natural. More ambience. I also actually had people that were unaware of the device come in the room and state that they "felt good" in there. I can only explain that it enhances the listening experience in a visceral way.

I was sceptical at first as was my wife and concerned about possible hazards, but after some bench testing and exposure to X-Ray film, I am convinced that the emissions are very low and not a hazard to human health. I wish I knew how this thing works. All I know is that it does work.

I borrowed one from a friend. When I had to give it back, my system sounded broken. It is the only power conditioning product I have heard that I did not see any obvious downside.
I am 'the friend' above. I have two of them, and they aren't going anywhere...
I'm having a bit of a Clever Little Clock deja vu.

Can anyone explain what's the difference between the various products they
offer? Why the Symphony Pro instead of the RT800 or the regular Symphony.
The Website is not exactly wonderful in this or any other regard.
I think it is a 20MHz 100mW emission, but it may also affect the power line. I have to try some battery experiements to determine this.
