Acoustic Revive RR-77 - Schumann Resonator Ultra-Low Frequency Pulse Generator in a fantastic condition. Audio equipment: by generating the Schumann Resonance with the RR-77, there is an effect that it neutralizes electromagnetic waves generated from an audio equipment and external harmful radio waves. When interference of electromagnetic waves and radio waves that exist among equipment disappears, it becomes possible to reproduce clearer music, improves S/N ratio and the distortion is reduced. Listening room: also, by generating the Schumann Resonance with the RR-77, there is an effect that neutralizes harmful standing waves, and has the effect of improving the viscosity of the air in the listening room.

The sound is audibly improved with the RR-77, and the depth/resolution of the sound is increased significantly. Listener: it has been established medically that generating the Schumann resonance activates the cellular immunity. And it is also said that the Schumann resonance produces relaxation effects, and the attentiveness is raised greatly. You can hear the details of the sounds that could not be heard before, when using the RR-77.

Conclusion

The RR-77 pulls off a real magic act in accentuating the musicality of a recording and hifi rig. The non-musical elements of the recording process such as soundspace, soundstaging, imaging, extreme detail recovery and so forth all have a dollop of naturalness applied to them so that they don't distract you from the musical elements of tone, melody, rhythm, emotional impact and musical flow. Those non-musical artifacts are still there but now in complete support of the music to never draw your attention away from the music as some audiophile-style systems tend to do.

With the RR-77 doing its little magic act, I can listen all day long with zero listening fatigue. If anything, a listening session becomes energizing and edifying and when a long nocturnal session is over.
At $300 It is a musical bargain though at that price -- or any price really -- for what it does to transform the listening experience. The RR-77 is a music lover's Blue Moon winner if I've ever seen one: absolutely, unequivocally and enthusiastically recommended.
