My favorite audio accessory of all time is the Acoustic Revive Schumann ultra low-frequency pulse generator, and I am delighted to award the Acoustic Revive RR-888 Schumann Generator a 2016 Jeff Award!

Here you can see the RR-77, RR-777, and the RR-888 perched on my mantel (left to right).

I've used every version of of the RR, spanning the last nine years:  the first RR-77 (now discontinued), the second version, the RR-777 (now discontinued), and the current RR-888, spanning the last nine years.

I have RR's in every audio & video room in my home, and I couldn't live without them, as they make such a meaningful difference in every music & video system I've used them in.

The RR-77 was the first Schumann generator to be released, then followed by the RR-777 (which has four times the output of the RR-77), and the current model is the RR-888.

The current RR-888's most obvious difference from the RR-777 is the gold finish of the chassis. They both use the same power supply for the same amount of Schumann pulse strength. According to Acoustic Revive, the RR-888 has an improved "accuracy of the waveform" and a "further low-noise circuit" that offers a performance improvement over the RR-777. It's all good.

I use two RR's in my main system, an RR-77 & RR-888, one RR-777 in my Leben CS600 & Harbeth Super HL5 system, and one RR-777 in my SPEC RSA-M3 EX Real Sound Amplifier & Stokowski Altec A7 Voice of the Theatre system.

Here's how they work: The Acoustic Revive RR's are ultra low-frequency pulse generators that are stand-alone active devices that plug into a wall outlet (but not your HiFi rig). Acoustic revive says the RR-77 generates a 7.83Hz Schumann frequency pulse that 'shields' your Hi-Fi electronics and listening room from radio frequency interference, and thereby improves the S/N ratio so the electronics perform better. Essentially, they are saying that it does a similar thing as a Faraday cage, like the Faraday cage does that Pete Riggle has surrounding his listening room.

What they do for the sound: I've found that the RR's do some pretty interesting things, with the sound becoming more natural, smoother, and more musically lifelike. Space also opens up in a recording's acoustic, with the music enveloping the listener more, and notes decayed in a much more natural fashion. The edge, grit, or glare that was to be heard on noisier recordings also became more tolerable.

The RR's make a significant improvement in every system I've tried them in, and I wouldn't ever want to be without them. In fact, I think every single friend of mine that frequents Jeff's Place has bought RR's after hearing what they did for my systems.

The RR's are good, real good, and I recommend them without hesitation as a way to easily improve a hi-fi system's performance.

Please join me in congratulating Mr. Ken Ishiguro (Acoustic Revive) and Mr. Yoshi Hontani (who exports Acoustic Revive products to the world), for designing, and making available, such outstanding audio products like the RR-888. Thank you!
