CAD had a similar device on demo at Oxford Audio last Saturday. When I say similar, it was in fact very different. This is a simple black box, made of metal and is filled with electronics (I'm not sure what), not with soil, minerals etc. This was a one off prototype unit, which if I recall correctly, will retail for about £1400. The similarity is the claim that it can reduce unwanted RFI interference etc. Something to look out for in the future.
