Some people hear nothing, others have reported great improvements. I once walked into a room and while the music was playing, the dealer turned it off. I felt sick to the stomach momentarily, but once I regained my equilibrium, I didn't hear any difference and told the dealer so. Whereupon the dealer turned it back on and I felt sick again. When he asked me if I now heard the difference I told him "yes" so that he wouldn't turn it off again and make me sick.
There were others in the room who didn't notice the turning on/off. Yet others who said that there as an improvement in clarity and soundstage.
Roch, just a tip which might help...try a swab of grey coloured electrical grade tape over the LED. Works a treat & is safe. I have an RR-777 in my audio room connected to a King Rex Mk2 psu via a custom short umbilical with a gold neutrix connector. The RR-777 is said to be 4 times more powerful than the older RR-77, and forum feedback suggests the KR Mk2 roughly doubles the effect of the RR-77. Also, placement is important. Acoustic Revive recommend placing the unit atleast 6ft off the ground, and preferable between the speakers facing the listening position. I have mine just above the LH speaker. There is definitely a calming effect. The effect is subtle, but the music seems a bit more free and liquid (or continuous). I leave mine on 24/7. As Eric remarked in his review of the RR-777 "Since these units work on the listener, the effect on each person varies". You can only try this device for yourself and see if it provides a benefit. The above setup tips should help. Here are some photos of my setup..
Hi Barry, the reason results vary so widely is that the Schumann resonance works on the listener, not on room acoustics as such. From that we could conclude that human physiology is more variable than room acoustics.Thank you to all those who have responded.
Really appreciated.
Also found an Audiogon thread on this which was a lot more positive than The WBF replies.
It's a puzzle that people have such different experiences. I guess you just have to suck it and listen so clearly an audition before buying or finding a good used one.
Thanks.Hi Barry, hope you're good?
I tried one a couple of years back in the room you visited but with a slightly different system. There was nothing I could put my finger on and ultimately I didn't miss it when it was gone.
As others have said the response to using them varies widely, the dealer I used swore by his and used two. The AR grounding conditioner I tried at the same time does make a difference and I bought one, that didn't work for him so go figure!
You're welcome. By all reports the RR-777 is a substantial step up from the RR-77 in terms of power and coverage. The RR-777/KR Mk2 combo imho negates the need to use 2 RR-77, unless you're talking about a very large room. Let us know yours and your Bonsai trees impression of the RR-777 when it's on deck.Thanks for your tips and link. What I own is the old RR-77 (2), I also have the King Rex Mark II LPSU. Just ordered the new RR-777. I will try it also on my Bonsai trees since they love music, but not heavy rock or metal, believe it or not!...

I agree with Mike Lavigne on this one...no real need to know how it works, but should be able to hear something.

Bodhi.
This gizmo appears to be a solution in search of a problem. That last thing I want in my stereo room is some do-dad that is working me over physically. Or, it claims to be working me over physically. Gary said it made him sick.
