Roger, I had a good friend who owned one of these. The sound it captured and reproduced was amazing, and the comparison to a Stradivarius is an apt one. When his coastal home burned to the ground, it was not his most expensive possession that he lost, but the one he felt most badly about given the rarity of its ability to rate a 10 on musical reproduction from a radio signal.
