I have seen a few things that are useful from Audio Science forum. However, I have noticed that they are very firmly in the mentality that is common from traditional engineers: "if you can’t measure it, it doesn’t exist". They put a huge emphasis on distortion measurements, which we over here at Audiogon know does not actually tell you if a product sounds good.
I have seen a thread at Audio Science where the OP started a discussion on a particular piece of equipment and his initial thoughts on sound quality. He then went on to discuss how he wanted to see what the piece sounded like after burn in and different power cords. Immediately, there were at least 5 different forum members posting and telling him he was basically a complete idiot (i.e. "there is no burn in" and "power cords make 0 difference"). And then very soon after, they closed down the thread to prevent any more "controversial" posts! It was unfortunate, because I was actually interested in hearing the OP’s impressions. I can’t remember the actual item or I would post the thread here.
