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?

I have many of these. Started with some of the $10 ones.
Initially two in the lounge with music.
Tried on a bunch of different music.
Hard to pinpoint what the difference is.
More authority to the music; a tighter grip.
A little more depth as well."

Then progressed to the Chartres Mk3
Chartres SE 4
Chartres Mk.V
from Jerichojason on EBay (David in Indonesia).

Have the MkV and SE 4 with my stereo.
The two Mk3s are in my classroom, as well as the two cheapies.

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