BSG's øReveel

If you were fascinated, as I was, by JA's February 2013 review of the BSG qøl Signal Completion Stage but were deterred from satisfying your curiosity about this unusual device by the asking price, you no longer need hold back. In the ReveelSound room, BSG's Larry Kay showed and demonstrated his new, tiny and inexpensive implementation of the technology in the form of the øreveel. Contained within the small package in Larry's hands is an all analog in/out version whose size and connectors clearly indicate that its target is headphone use. When I told him that I don't listen to headphones, Larry made the convincing demo with a desk-top system. The unit is powered by a rechargeable battery and, although I didn't ask, it looks like it should also run on the included power supply. Price? Just $119.95 and an ear-opener.
