Review: Acoustic Revive RR-77 Tweak
| Post removed |
I was pretty skeptical of this, and don’t usually do fringe stuff, but was intrigued enough to get an RR-888. I experimented with positioning it in several different places in the room, just using the wall wart that came with it. My best compromise is about 6 feet off the ground, at a point perpendicular to the speakers, aimed from one side about a foot in front of the speaker line. I eventually bought a linear power supply for it- a bench type with multiple channels, a large toroidal transformer, and the ability to limit voltage and current, connected with Switchcraft barrel plug and banana plugs. I like what it does, and have now idea how it works- I gather the effect may be on the person, rather than some mysterious blocking of EMF. And no, I don’t take substances when I listen or otherwise. :) |
clmelis 10 posts 06-28-2016 9:39am That's the official line. The current model is the 888 anyway. It's not painted with magic symbols inside, but it WORKS! I saved $400 for the same performance. I'm happy. I happy if you're happy. But I kind of doubt your eBay unit has the same performance as the real McCoy. I never said the eBay version doesn't work. But everything is relative. That's why there's an RR-77, RR-777 and RR-888 and why aftermarket power supplies further improve them. |
I have had my RR-777 for over six months now. I found a "Non official" used one on ebay from Japan. Cost $180, which is more in line with reality.It looked new , by the packaging and condition. The effect is of getting immersed in the soundstage, rather than having it laid out in front of you. There is a more relaxed 3D quality to the sound. In my texts with BAGRANT, he commented that the sound is more annoying with the unit turned off! That's how you notice the effect most- you miss it when it's off. There is now a seller of schumann generators with adjustable field strength and massively greater output for the same price. Much cheaper than the questionable practice of using multiple units. How would you know they are producing their pulses in unison? It has dual chartres pattern coil antennas. Look at this on eBay http://www.ebay.com/itm/262452147803 There was a bench test video demonstrating the increased output compared to the 777.... Has anyone tried it? |
I found that this über cheap Ikea shelf was perfect for the task of elevating the wave generator. http://www.ikea.com/us/en/catalog/products/50282177/ |
"Everything" makes a difference... right? Try this one: play a cd (however you typically treat or don't treat it before inserting in the machine). One track should do it. Next, remove the cd and place it, label side up, on the Schumann Resonator, for five seconds, or longer, if you like. Re-insert and play. Do you hear a difference? |
Sabai, I would like to add "vibration isolation" to your list. My Schumann unit is placed at the end of a piece of maple, sitting on a shelf at the rear of the room, six feet high, extending into the room. The quality of the isolating device changes the sound. My choice is Symposium Rollerblocks. My unit, "Earthsafe Whole House" from Less EMF Inc., has two nice features. It has a ground cord to inject the signal into the wiring of the house (their claim). And it has a dial so you can adjust the output of the unit. I can coordinate it with a Synergistic Research FEQ and a Kemp SR that are in the front of the room. |
Using Schumanns effectively is not a simple matter of unboxing and turning on. Among those interested in Schumanns in the audio community, I do not think that there is a good understanding of how to optimize their use. There are 5 factors impinging on the effectiveness of Schumanns: 1. The kind of Schumanns used (not all Schumanns are equal). 2. The number of units used. 3. The location of the units. 4. The height of the units. 5. The direction of the units. It takes quite a bit of experimenting with Schumanns to figure out what works best. In my system, I have one unit of Schumann version 1, 6 units of Schumann version 2, and 8 units of Schumann version 3 -- with more to come. Cumulatively, Schumanns can greatly improve SQ, with the result being more enjoyment of the music. Schumanns work synergistically with Steinmusic Harmonizers, Shakti Hallographs, QRT Symphonies, Synergistic Research ART and other tweaks and accessories. Each addresses a somewhat different but complementary aspect of SQ. |
I can vouch for Bagrant's review.Finally got over to his place a couple of weeks ago for a fun evening of music. Never heard his system sound so musical,warm & spacious! Hope he will come over soon & bring the RR-777 along. I have already decided to get one if it has the same effect on my music room/ system/ wife! |
Interesting comments regarding the perception that the 7.83Hz Schumann frequency pulse generator affected one of the Audiogon member's voice (or, at least, he subjectively believed that to be the case). I have this item, albeit a different brand, and have noticed that when it's turned on, my personal "staying power" is enhanced while both the sound and this author are soft and flabby when it's turned off. |
I have an RR-777. At first I thought it didn't work. I was listening for more bass, detail, that sort of thing. Once I heard it, it became impossible to live without it. I leave it on all the time because the listening/living room feels better with it! Its effect on my voice is obvious. Without it, my voice sounds drier and more inside me. With it, my voice is more liquid and fills the room more. I hear the same difference with my bamboo flute. My 10 yr-old who cares nought for hifi, could hear it with her violin. She was mystified how flipping a switch on a little box, could change the sound of her playing. It was interesting to me to watch her try to describe what she heard, She has no vocabulary for sonic differences. She liked my "wetter," as a description of the sound with. |
Yes Nhaudio, try explaining to your wife how you bought two more...HA I bought a different brand here used. Same findings, I did finally pry it open enough (was glued tight) to see a PC board inside. It does nothing for me. Mine has a red power light. Maybe the blue power lights sound better. I am still trying to hear a difference with the Quantom Symphony Pro I purchased here. Maybe I should stop listening to music and just listen to gear. |
Nhaudio, I had the same experience until I focused on placement. Schumann devices work well in multiples. You will likely get the best results with Schumann devices by placing 2 of them at least 6 feet off the floor -- preferably on top of the speakers -- with a third unit in the middle of your system just above ground level. |
I received the second rr-77 today. First impression: unbelievable. The speakers completely disappeared and the soundstage is huger than huge. Front / back is very impressive and so is the width. Tonight I'm going to experiment with placement because with the first rr-77 I've noticed that this can add a lot. I'll share my "final" placement of the two units and let you know howe it sounds.... |
I bought the new rr777 with king rex mk 2 psu. Wohhhh! Just can't believe it. I have a dedicated listening room and without rr777 it sounds very good. With rr777 it sounds like audioheaven. Why? Enormous soundstage, width and depth and a far greater tonal palet! With classical music all instruments have much more air and their one space. The "you are there" factor. It's very addictive. I'm still experimenting with placement but so far 1,5 m high on top of the cd player sounds the best. I'm so excited I've ordered a second one and king rex. I have the king rex already and expect the rr777 next week.......... |
Hi Dnobel, Thanks for your direct reply. I still have and use the unit and feel I do now understand its effects -- to sum up there is an ease about the music and it also seems more dimensional. Results have varied depending on placement, including height. IMO its a worthwhile tweak for the used price I paid. Not sure about spending $600 for one new based on what I'm hearing, however this is def a case of YMMV, and perhaps others who claim a 'profound' change are really getting their money's worth. |
Tholt, I just stumbled on this thread and saw your several-months-old query with no reply to date. I have owned an RR-77 for well over a year now. While I saw that one person on this thread claims to be able to feel the energy coming off the Acoustic Revive when it is plugged in, I cannot. The only physical evidence I get that it is powered up is the blue light. On the other hand, I can hear a definite improvement in the music when it is on, mostly involving a deeper, wider soundstage. For me it is perceptible and significant, but apparently not as dramatic as others have reported. I believe the relative effectiveness of this tweak depends on the convergence of several variables: the room, the system, the source material, and the person who is listening. Listening to the same music in the same space through the same equipment, some people will hear a dramatic difference, some subtler improvements, while others will hear virtually nothing. Experiment with different device placement and listening to different kinds of music at different times of day. If it doesn't do anything for you...well, it is what it is. Maybe it's not for you. |
Hello, another revival of this thread. I just bought a used one, and do need to follow up with Krell Man's question of how one knows it's working? Is there any physical signs from the unit itself (ie vibration and/or sound, other than the light) or do all of you know it's on because you just hear it's effect? I have not found profound effects in my case, they are subtle, and I am not entirely convinced it's not even psychological. I have only had it for an evening so I will do more listening. At any rate, I put my hand on the unit and didn't feel anything. At least the light comes on when I turn it on. |
