Acoustic Revive RR-77, 777, 888 Schumann Generator


Love to hear from anyone about their experience with these devices.  Long story short, I have an RR-77 in my room.  Bought it off Audiogon about ten years ago.  Every once in a while I look at it and think to myself "stooopid".  So I turn it off... then back on... then off... then back on.  Then I leave it on because what it does is wild.  And it does wildly good things to the sound in the room. I have it positioned above 5', and off to the side in the room.  It's like an ECU tune on your already high performance engine.  It's like buying a chocolate from a storefront in Brugge, rather than a Godiva from your local mall.  

I've read the threads.  Looked over posts and reviews on the interwebs.  It works and anyone who says it's snake oil... whatevs.

Anyone ever compare iterations of this device?  77 vs. 777 vs. 888?  Any discernible improvements?

I have not delved into any other AR devices.  Anything particularly noteworthy?

Hi Miller,
According to all that I have read, about 5 feet is a good height, and as I said, that happens to be about the height of my speakers on their stands. I would definitely not place them on the floor.
All those units are toys. To do it correctly you would need a several hundred watt semi-pro power amplifier good down to 7Hz and a 1000 feet of wire looped around the room to act as an antenna.
In my room even these toys gives me audible positive effects, i improve them by connecting them in a grid and using my "golden plate" on them...

Your post remind me of those who speak about acoustic treatment using many thousand dollars of materials... I use homemade no cost materials, homemade absorber, diffuser, reflectors, and resonators, and at the end i succeed to have top audio experience for peanuts...

Listen with your ears and experiment.... The sound waves will not know the price you have paid for your materials and devices controls and will act nevermind the price in a positive way or not.... Your ears will dictate the road to take one day at a time....

Simple....
Congratulations speedskater! Only 5 posts and you're already a know-it-all! However, I regret to tell you that these "toys" still do work.

That’s for sure. Professionally made often times does work a lot better. But also a lot of times its surprising how much improvement there is to be had from really cheap alternatives. Springs, just plain old ordinary springs, are surprisingly effective. Townshend Pods are so much better they’re in another league. But so is the price. You get what you pay for. Which is not always true. But that’s another subject for another day.

So the cheap circuit boards came last night. About the size of a pack of cigarettes, only half as thick, they sure don’t look like much. Took a couple boards from the shop, used a rubber band to hold them on there, plugged one in. Blue lights. No sound. Zero. Just the blue lights. Leaned them up against the side walls about a foot behind me and pointing straight out into the room. Unplugged.

Played some music. Plugged one in. Right away noticed a smoother more natural sound. Hmmm.... unplugged, brittle hard edge. Funny, never noticed that before. Sounded pretty good before. Now sounds kinda flat. Plugged it back in. Sure enough, way better, more depth too. Crazy!

Plugged the second one in. Wow. The front of the presentation has moved forward to where it seems in front of the speakers. Not the whole stage. Just the front. The back extends even deeper than before. Forward can be bad, like aggressive in your face. This isn't aggressive at all. More like closer than forward.

Everyone who hears my system winds up complimenting the imaging. Its even better with the Schumann generators. Especially the sense of space, the size and acoustic space of the venue is a lot easier to hear. There’s a smooth natural sense of ease, which was already quite good but now is even better. If I start to think something is missing, unplugging proves yes indeed something is missing- an overlay of gritty tizzy glare that might once have been mistaken for detail or extension but now turns out to have been noise. Like a whole layer of white noise has been removed. Something like that.

mahgister, you are running 9? This is only two. I’m ordering more!
