This is my point exactly. Your opinions are not a definite fact, but your own opinions. If some people think that the build quality is lacking, you don't have to come in and reply that it is very adequate. Constructive criticism is what helps improve companies. Personally I have not heard how it sounds, but I am very interested in this product, which is why I read this thread. Please stop being so defensive when others criticise your "holy grail".
Well he does have the right to disagree and post his own comments but I do see your point at the same time. As you said you have never heard them yourself so you won't know your own truth until you try them yourself.
