These AA threads on crystals linked below go back even further than the ones Sabai posted. I came out with Brilliant Pebbles in 2003 at the London HiFi Show. They had already been around for a few years. A good time was had by all. Well, maybe not all. 😀
Hi-Fi News Show, London, Sept 2003 -- Audiopax/Ecosse/Meitner exhibit coordinator (Precious Music, Scotland): "Now, if I say that dozens of people said we had the best sound at show, many others said we had the best sound they had ever heard, many dealers, competitors and reviewers came round to check out the room and in particular the Audiopax Amp and Meitner dac...well you can imagine we felt pretty pleased with our efforts." (4 Brilliant Pebbles were used in this room -- one on each Audiopax speaker and two in room corners.)
