The Acoustic Revive RR-888/777/77 is an ultra low frequency (Schumann Resonance) generator. This ultra-low frequency (7.83Hz) is also naturally occurring, being the lowest of the frequencies generated by a lightning strike. The RR-888 generates the same pulse and has the same effect albeit in a smaller radius. After only a few minutes of being on, the air in the room feels less heavy, more pliant and the sound of the system takes on a smoother, easier character. There are a few reviews online:
Wonderful equipment and your room/set-up looks beautiful too. I'm curious what country you live in, because I don't see B&O speakers around much. It is really nice to see their high-end speakers being used. And how do your main speakers sound?
