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?

LOL roxy you crack me up... I’m still laughing...

I think I’m gonna go for a few and mount them at the 3 - 4 foot level. Hope it mellows the grandson a bit, too. LOL

oldhvymec,
I'll be interested to see what you think. I'll bet that you won't want to be without them.

@jerrybj,

What are the differences in SQ between the cheapies and the Chartres?

Having used two of them for months now, I wouldn't describe the effect as just one frequency extension or depth of image, although those seem improved. For me, it is as if the music suddenly became more organized, and something "busy" in the music disappeared, leaving a natural flow, and exposing rhythms that I hadn't noticed before.

The blue light looks nicer at night!

I continually added upgrades over an 16 month period, so the changes were hard to keep track of.
