There is absolutely no doubt to the fact that this is a marketing/PR piece. It is a very poor PR effort however, with little integrity. To open this piece with a blatant slam to his competitors (in no way veiled) was a very poor choice on the part of Mr. Von Schweikert. I have no doubt that the paper is based on genuine R&D (science) and that the resulting tactical implementation is effective. I would also like to believe that one not need spend ridiculous amounts of money on exotic cabinet materials and that this approach by VS does provide a cost effective solution. Furthermore, my comments are not intended as a slam to VS speakers but to the lack of integrity taken in publishing a public article with such demeaning reference to the competition sounds more like politics.
