Come again? Of course I know he sells diffusion products. A bookstore owner who is republican doesn't become democrat because he also sells books about them! I have also seen that video you posted and hence the reason I know about the flaw in that experiment. None of this has anything to do with you characterizing his believes as: "So in fact Ethan Winer does believe in full sounding rooms with reflection, but he believes in achieving that with even dispersion." Quote me where he says that. Or anything close to it. I posted a picture of his room which shows no diffusion products at all. He is very proud of the sound he gets in that room and has discussed it many times over the years. That again is how I knew to go and dig up his room. Ethan is a prolific posters and it is so simple to read his views across literally thousands of posts. Here is one where were both participating in: There is no suggestion to use diffusion. Or believing in a room full of reflections. He is opposed to letting those reflections be there. If it were up to him, he would block them all. As he should given how his hearing has evolved (trained) to hear their effects and consider them something undesirable. Note to bigshot: if Ethan is your hero, see how he is also advocating carpet on the floor as I did.
