Wellfed, in my case a suspicion is a step below an opinion in the hierarchy of belief statements. After reading multiple websites and threads on the issue I still haven't gotten enough detailed information to say what is really going on with the RealtyCheck process, but I've still gleamed enough information to make a conjecture. I am not saying RealtyCheck doesn't give the results people have reported, but that the sonic improvements claimed can be equaled by other CD-R burning procedures. I could very well be wrong, but RealtyCheck seems to be a very refined application of a phenomena that was reported more than a decade ago. As a turnkey system (and depending upon the pricing of the proprietary cleaner and CD-Rs) I suspect it could even be a good value for someone interested in taking the time and effort to correctly apply it.
Miklorsmith, please report back your findings on the comparisons. In my opinion your opinion on the subject would be most valuable.
