Bill the only problem with your argument it that those large companies that you just mentioned do get the certification, for them it is nothing to spend the money. It is the small guys like Enlightened audio design that have not been paying the bucks although I believe that even their new stuff is. There have been unfortunatly some instances of companies sending in some receivers for certification then changing the boards at a later time. I believe that Lucas has cracked down on that and also decided to offer the different ratings. I certainly do not look at that logo to make my decisions but lets face it I am a far more edjucated consumer then most and it sounds like you are as well. This is for the guy that knows nothing about audio, and wants a good sounding system. Now does Techniques really offer a THX amy????
