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 found that different cords clearly changed the effect, and could descern thw characteristic of the cord making the sound brighter or warmer etc.

It.does have an effect with better seperation and more naturalness.
