I am reminded of the words of Groucho Marx..."I would not want to be a member of a club that would have me as a member." My interests are varied. As they are related to audio, I have been fascinated with it since childhood living in an orphanage. I could not hear music when I was young, only sounds. Music to me was strange noises. I could easily identify the sound of a General Motors V8 as opposed to a a Chrysler V8, for example but they were just different sounds...like music. Some music had different "firing order" and that interested me. I have no education such as college, university, high school or anything like that. In recent years, I have come to believe that it is not the source of shame that I once believed it was. How some young people have endured several years of higher education and escaped having learned absolutely nothing provides fodder for my curiosity. Reproduction of music a fascinating adventure and one that is not often met with success. There is still nothing like the real thing. Some headphones come close but speakers rarely do. In this modern age of thousand watt car stereos...what difference does it make? Soon the occupants of the velocipedes will be deaf anyway. For me, the quest for true reproduction of sounds is my interest. I seek excellence rather than perfection as it has become clear to me that the sound of amplified music can never be as good as the sound of a beautiful voice sung live or the sound of a wonderful musical instrument. My business is that of robotics and related equipment but I have built a lot of equipment over the years related to audio as a hobby. Also, from time to time, I find things that interest me at estate sales, auctions, on line, and so forth.
