I too looked at the Perfect Meditation website, and what strikes me, is that there is not mention of the names or details of the people producing the CDs.
This seems to be a trend in this field, because I have come across other companies producing similiar material, where they mention that it is a a "group of researchers" who produce the CDs.
Why cannot companies state the names of the actual people who create these recordings? Learning Strategies describes the names and educational backgrounds of people such as Paul Scheele and Pete Bissonette on their web site, and on their products, and you can actually see and shake hands with them when you go to a seminar!
It gives the company and the products so much more credebility and makes it easier to trust the genuineness of the technlogy, than when you have a "mysterious" group of researchers producing them....
