Title: Acoustic Revive RR-888
Post by: rollo on March 13, 2018, 08:27:30 AM
   If you like what Salt crystal lamps offer in sound improvement these babies take the cake. Do you desire the recording venue in your room ? DONE. Do you like an open sound stage ? DONE.  Do you like presence ? DONE.
   Cleans your air, makes your music sound better, good for your health a no brainer. There are several commercial Shuman Resonaters out there however this one takes the cake for me.
    Even Herbie Hancock uses them after hearing the difference. He stated his piano never sounded that good. He will NOT record without them.
   Good for Herbie good for you. Everyone needs to experience this. Mind boggling. Not a dealer but I wish I was.

Joe Cohen, nice guy!

They make some very cool and effecacious products. The CD treatment machine is amazing, I heard it before and after on a homemade CD-R. They make a outlet bar that is hollowed out billet aluminum filled with tourmaline dust, it is amazing.

Thanks Nick. There are alternatives out there less expensive however they would need a bigger wall wart of at least 3A. These devices ARE the real deal for health and sound improvement.
Even the Salt crystal Lamps work. Just need several in room [6]. Clean air to boot oh my!

 Thanks Rich That is who I purchased from. Joe is a sweetheart. If anyone wants any AR gear maybe I can help as Joe is a distributor not retailer. BTW you are spot on with CD device. Another good one is the Furutech, both have a VG affect.

For CD treatment nothing works better than a magnetic tape bulk eraser.

But wait!  CDs are not magnetic says you.  Fact is it is the inks used on the CDs that is.  The most common pigments used contain ferric and ferrous oxides.  They ARE magnetic.

I poo-pooed that whole thing until I tried it for myself with other listeners that had no idea what I was doing.  Most common comment was why did those two CDs sound different when it was actually the same one.  Every (EVERY) person heard the difference.  Photons, those almost massless little critters, are easily moved by magnetic fields.  That is what I did in the semiconductor industry: bending photons and ions with intense magnetic fields down the flight tube of an implanter.  Real physics at work, not voodoo.

First time Iíve ever heard an explanation why. I thought it was a static electricity issue. This reminds me I had a Bedini Ultraclarifier many years ago

Ripping the CD to a data file solves any real or imagined magnetic problems, static problems, reflective problems, vibration problems, disc error correction, laser diffraction, etc, etc. Leave the physical and all it's problems behind. :)

Reducing jitter and maximizing sample rate offer greater improvement than treating a CD.
Title: Re: Acoustic Revive RR-888
Post by: _Scotty_ on March 14, 2018, 03:14:18 PM
It should be mentioned that you will have better sonic results if the drive you use for ripping has C2 error correction capability. A full explanation of the hows and whys can be found on the Web.
 dBPower amp has the ability to apply C2 error correction if the drive has the capability. EAC can also do this. Error correction is not the same as error interpolation, which is a guess at the missing data. Burst ripping employs interpolation only. Which unfortunately is sometimes the only way to get a rip of damaged or weird CDs.

Donít doubt that at all as to jitter and sampling rate. It would be an interesting experiment to use the devices to correct magnetism, static, diffraction, etc and then immediately rip to a data file.  Then compare the CD to the data file. Iíve never done it.

   You who have great ears WILL appreciate the sonic improvement. Shuman Resonaters work. As I said good enough for Herbie Hancock good enough to try.
 BTW guys for static nothing more effective than the Mapleshade device. Circa $35.

Iíd like to understand in more detail why is there an improvement after demagnetizing a disc?
Nick

I'm not sure there is a whole lot of detail to it. Magnetic fields on the disc can cause a "bend" in the laser light path whick can result in the reflected light not missing the photo sensor and certain bits not being read properly. If the magnetic field was static it would not be a problem as the photo cell could be adjusted to compensate for the4 bend, but since the discs is spinning, that means the magnetic field is moving around and the displacement from the intended laser path out be random in nature causing data errors.

Nick, using this device accomplishes the same thing as the Bedini Ultraclarifier.just not automatically as you would need to hold down the power button on the demag unit and move it around by hand.

And if you do use one of these devices be sure that it is always moving while it is on and move it at least an arm's length away from the CD before letting go og the power button t the sudden collapse of the magnetic field will re-magnetize the disc (or at least that is how it worked when we bulk erased reel to reel tapes when  I worked at the radio station.

Doug,
The link about the Telos diffuser and mention of alpha waves made me recall an incident from 25 years ago. At that time, I had severely injured a hip muscle and was constantly in a lot of pain. I had a dance partner at the time named Isabel who years before had been at UCLA and was involved in a study about pain control. Over the phone one time, she walked me through a sequence of mind relaxation and uttering the yoga phrase ďomĒ repeatedly. Doing exactly what she said put me in a state of mental and physical relaxation and the pain ceased. I asked how this was possible and she said the study found that producing alpha waves somehow caused a body frequency response less than 20hz? and below that point the body could no longer feel pain.
As I only ran into her at dance functions occasionally, I lost track of her, but was able to recall, as best I could, this incident of so many years ago

Iíd like to understand in more detail why is there an improvement after demagnetizing a disc?
Nick

I'm not sure there is a whole lot of detail to it. Magnetic fields on the disc can cause a "bend" in the laser light path whick can result in the reflected light not missing the photo sensor and certain bits not being read properly. If the magnetic field was static it would not be a problem as the photo cell could be adjusted to compensate for the4 bend, but since the discs is spinning, that means the magnetic field is moving around and the displacement from the intended laser path out be random in nature causing data errors.

Nick, using this device accomplishes the same thing as the Bedini Ultraclarifier.just not automatically as you would need to hold down the power button on the demag unit and move it around by hand.

And if you do use one of these devices be sure that it is always moving while it is on and move it at least an arm's length away from the CD before letting go og the power button t the sudden collapse of the magnetic field will re-magnetize the disc (or at least that is how it worked when we bulk erased reel to reel tapes when  I worked at the radio station.

Thanks, Tom. It appears error correction, or actually lack of absolute error correction,  may be the culprit. My CDs are on a data file, but there are some new ones I need to rip. So my thinking is if some of these gizmos work, why not use them before ripping to possibly get a better sounding permanent result. Maybe I have a demagnifier and antistatic device in an old musty audio box in the garage. Gotta check.....

  After living with the RR-888 for a couple of weeks now I can now appreciate what they offer. The recording enviorment of the recording comes though in spades. The decay of harmonics has expanded to my listening chair. Just fills the dam room. I can feel the sound now. Amazing. It is when you unplug it the effect just goes away.
Doug has supplied a bunch of choices to choose from. BTW two make it even better. A no brainer for any system
Besides the sonic benefit I just feel better. More relaxed with no sleeping issues.
One does not need a high end system to hear the improvements which makes it appeasing. I'm hooked, one would have to rip it from my dead cold hands.

from what i can tell, the "chartres se 4" (~$260 shipped) iteration looks much more powerful than the rr-888(shown on the right; pic on ebay is larger):

and their less expensive model (~$75 shipped) looks a mite better than the rr-777:

the less expensive ones on amazon seem to be closer to the original rr-77.  it seems that if you want several, these less expensive units would be the way to go.

The RR-888 is available at musicdirect.com for $685.   I'd worry that the one on ebay is just a knock-off.    At the full price, I'm pretty sure it will work wonders to my ears.   At $39 from Amazon,  I'd be less easily convinced.   

OK, kidding aside, I did try the early RR-77 many years back.  Thought I heard/felt a difference but who knows - may have just been expectation bias.   I also got caught up in the Alan Maher tweaks and cyrstals as well.   We've all tried lots of different things over the years.   Like all tweaks - it never hurts to try.   Just wish there was a UsedTweak.com site where I could flip some of the stuff I've accumulated over the years.

I think you are on the right track as to why. I think it would probably be the lower of a need for error correction as the demag process will remove a problem that could introduce errors. Keep in mind that into most cases what we refer to as "error correction" with realtime CD playback is not really error correction but rather interpolation, a process in which the CD player makes a guess at what the next value should be based on the read values around it. So the less guessing you have to do, the better off you are.

  OK we compared RR-888 to RR-777 and the 888 was more affective. Using a more powerful power supply [3.5W] made the affect even more noticeable.
  When unplugged during demonstration the sound stage collapses, F'n amazing IMHO. Orientating them N.to S. also made an improvement over E. to W. go figure. Well our magnetic fields go N. to S. that is why.
  This is NOT subtle. Yes $685 is not inexpensive. The end result is that there are zero components out there that can bring this affect for $685.
  Going to try [4] units. My customer has two and we will use all of them , N,S,E and W. Yes I sleep better and just so relaxed.

Iíd like to understand in more detail why is there an improvement after demagnetizing a disc?

My experiences.  I posted a long thread on my old AC site about why and how a demagnetizer works on CDs and DVDs.  It is really a simple, but multi faceted application of physics.

Follow me here:

First is the static electricity build up on the CD or DVD.  Lexan is easily energized with a static field especially when spinning in a dry climate.  Basically a butt load of a single ion polarity.  The direct application of  a strong magnetic field disrupts whatever the polarity of the field is, IF the demagnetizer is used properly.  It must be pulled away very slowly until it is 2-3í away from the disc to not re-energize the disc one way or the other.

The BIG One though is the magnetic polarity of the disc at hand.  Photons are very low energy entities compared to other energy states.  A photon can be easily nudged one of 6 ways depending upon the outside energy field.  What does all of this mean?  The disc itself is not magnetic, but prone to an electrical charge. 

Then why would a bulk tape eraser have any impact on the SQ of rips?  Quite simple.  Most of the inks used to print CDs ARE magnetic.  Black is the worst due to the iron ( ferric and ferrous oxides along with lamp black) in the ink. Red is not much better, again, different iron oxides.  Doesnít seem like a big deal, but when these inks are spun at 600 rpm or so the energy field is multiplied by the speed.  A lot like the way a guitar pickup works:  More lines of force crossed = increased output.

If you do a lot of rips it is worth finding an old BTE.  They are not very expensive and beat the crap out of the commercial offerings out there.

Works good on vinyl, too.


I'm not sure there is a whole lot of detail to it. Magnetic fields on the disc can cause a "bend" in the laser light path whick can result in the reflected light not missing the photo sensor and certain bits not being read properly. If the magnetic field was static it would not be a problem as the photo cell could be adjusted to compensate for the4 bend, but since the discs is spinning, that means the magnetic field is moving around and the displacement from the intended laser path out be random in nature causing data errors.
