Some months back--assisted by a helpful reviewer's knowledge--, I saw the website and the President's posted system, and asked a question regarding isolation. I showed a respectful interest in his system, I thought. No answer came. I sent a second letter to the man, asking about isolation. No answer. With the 3rd letter, I criticized him for not taking the interest in someone's interest in his system. He answers back something to the effect, "I'm not a manufacturer and I don't have any obligation to answer your letter" (or similar haughty attitude). Is this promoting ideas about audio??
