Is there anyone out there who knows anything about Essence Speakers by Dale Pitcher?

I have read all the threads I can find on the web about Essence Speakers and about Dale Pitcher. I met Dale at the Essence plant in Lincoln in the early 1990s. I know about his eccentricities but found him to be a genuinely nice guy with a great passion for audio. I have owned a pair of early Gem speakers and currently own a pair of Gems from near the end of their production run. His speakers are amazing. I would like to become acquainted with other Essence owners and fans of the Essence product line. I have recently found and purchased a set of Essence Topaz 6 speakers from the mid 1980s paired with a pair of Topaz Subwoofers. Is there anyone out there with any literature, pics, documentation, history,  setup procedures, or an interest in having an informal club or chat room to share the joys and sorrows of these wonderful speakers?
