Acoustic Revive RR-77 Ultra low pulse generator

Chadeffect, I have not felt the butterflies, but I do agree about the effect. At Ozzy's suggestion I tried Vibapods under the unit with a hard to describe effect which, I think, is positive. I also tried the Acoustic Revive QR-8 quartz disc on the bottom inside as described in 6moons. I totally ruined the sound. I have not tried alternative power supplies.

Overall, I find this a mysterious box. It looks like a rip-off as it is very little for the money, but it has a very strong effect if you experiment with it to find the optimal placement in your room

Jea48, I don't think anyone, including the people at AR can answer your question. But since it has no connection with your sound other than being in the room and seem to have no resonance capabilities, I would have to suspect that its effect is on you.

Hi Tbg,
i have to say it is a very strange box. But it does have very nice effects on sound or me. Not sure which although I think I agree with your observation that it is probably me and not the system. Even my TV screen seems to benefit. I mean I benefit when I watch the TV!

Ozzy,
I think I will try the power supply. Is there a particular Kingrex supply that I should use?

Chadeffect , The one of I have is simply called a KingRex PSU.

I just finished auditioning the SR Plug from Kemp Electronics. The Kemp has the same effect, with the added benefit of adjustable signal strength and a long antenna, which makes it much less conspicuous and easier to mount than the Acoustic Revive.

I have to say, the effect was much more dramatic than I was expecting. I heard another level of detail in my music that I haven't noticed before. This would have ordinarily made this a must have, for $300, except for the physical effect the signal had on me. Within 10 minutes after plugging in the device, my eyes began to become dry and tired, my back and neck became sore and I had a slight headache. (I can also feel the butterflies and more intense effect when I move the antenna)

I wondered if I might adjust to the signal and not notice it if I just left it on all the time, but after 6 days the ill effects clearly weren't going away and I couldn't take it much longer.

These devices will effect every person differently. However, I suspect that many customers who aren't aware of this issue will love the effect when they first try it, only to figure out after 3 months why they feel like crap so much. Fortunately, I demanded a 30 day trial period when I bought this thing.
