In the past, I've commented negatively on Richard Gray, here as well as elsewheres. It's my position that he is a charlatan who designs expensive products which provide dubious benefit to the consumer and his 'Gray Papers' are a testament to a lack of knowledge about electrical theory and misrepresentation of reality. The fact that he's sold thousands of his products or that they may be seen in high end salons or shows like the CES in no way diminishes their dubious benefits. You will find that even that hallowed bastion of tweakism, StereoPhile, frowns severely. Read about it here for more insight. For those of you who are considering this product, I urge you to look elsewhere for nirvana. This is the road to perdition.
