Acoustic Revive RR-777 vs RR-888

[Steve]

:dunno: can't tell the difference between the two. I am using a KingRex linear PSU to power mine.

I'm curious about the artificially created Schumann Resonance output, so I am sending a RR-777 to a laboratory for an analysis of its output frequency, pulse/amplitude.

RR-777 was purchased new from a Japanese eBay seller.
RR-888 was purchased from an authorized dealer.

The new model is supposed to be more accurate. Apart from the plastic case color, IC minor revision?, the board looks the same.

Opinion anyone?

Nope. Just a change of colour and corresponding model designation for the Asian market. There is no difference inside the box whatsoever despite Acoustic Revive's claims. Let us know how the lab tests go

My RR-777 is the only piece of gear I have that I still cannot make up my mind if it does anything or not.

Bud, my understanding is the Schumann resonance works on the listener and not the room as such by affecting how we hear the music, therefore the affect can vary from person to person. Could you comment on the location of your RR-777 in your listening room (incl: height above the ground)? Also, have you paired your unit with a 13v King Rex Mk2 or similar psu? The KR Mk2 improves the effect of the RR-777 such that you don't need multiple RR-777's like those crazy guys in Japan :lol:.
