I'm not sure your point however every single manufacturer makes claims and uses wonderful language to describe their products. This is called marketing and also advertising. Read any high end web page and its there in black and white. Speakers, Cables, Electronics and even furniture.
We won't ever change that. Manufacturers are under no obligation to join this forum, or any other forum to defend themselves, and in fact most wan't to avoid this type of thing as to not get into these adversarial discussions.
As I said if readers have technical question they should address them to the companies that design and build the gear IMO as they might actually get an answer that satisfies them. I personally am not a technical person and that stuff does truly bore me.
If you dont care for the sound of something thats fine, it happens every day, every showroom, every show. Everyone has the ability to listen for themselves and make a decision as to what they enjoy, its the other nonsense that is truly boring. One last thought,just becasue something comes along that many like better does not mean that what came before is bad. That seems to be the kicker here I think, maybe I am wrong.
