A 6moons review did show a picture of the inside.
Here's a link to it.
If you check the other side, there are components where the solder points on the PCB are, relatively substantial to the QRT's, in addition to that rectangular coil that I suppose radiate something..

Thanks Hotbird, I was debating about whether I should give the Quantum Symphony Pro a try although I actually have heard the RR-77 in action. Looking at both their insides suggests to me that I can't go wrong with the RR-77. Placement is however a problem as I have nothing higher than 4ft behind the speakers. As it stands now the only place I could put it would be on top of the CDP which occupies the top shelf of my rack. You have one right, would it screw up anything if placed on top of the CDP?

  My bet if you place the rr-77 on top of the CDP, do use some isolation footers, like sorbotane. The transport when spinning discs may "shake" the rr-77, and the ripple wave of 7.83hz produced by the rr-77 may end up distorted.
  
  hmm, I will be getting the rr soon. its light and can be pasted on the wall with some good 3m adhesive.
  
  Perhaps like this?

    Actually when I heard it, the guy placed it on top of the CDP (because there was no other place in the room he could put it) and I came to the conclusion it was effective because of that placement.
    Correct me if I am wrong but 7.83Hz is electromagnetic and not a sound wave so in theory there should be no vibration?
    As for sticking it onto something, I did not think of that, so yes I could stick it to side of my "taller than me" CD rack and it would be out of sight. Thanks for the suggestion.

      My concern is that we spend much of our time trying to shield our equipment from electromagnetic fields, and here the RR-77 is sitting in amongst our equipment generating them. This cant be good for the actual signal, even though the RR-77 is supposed to work on the listener and not the equipment, it will still affect it and not in a good way.
      
      I know that the RR-77 is not supposed to be plugged into the same circuit as the audio system, but what other steps can be taken not to let its EMF affect the system?

        Please correct me if I am wrong but understanding is that the very high EMF in MHz rather than really low Hz are the ones that cause problems. I actually was not aware that the RR-77 had to be pluged into a non-audio circuit although I am not sure what would be able to sneak back into the audio circuit.

        I have two RR-77s. Although I don't have to worry WAF as she forced me into a separate room long ago, I have one between my speakers at just under the 1.5 m height. I experimented with several heights there although only my amp is located there. I used one of these tinker toy like wine racks where you can raise it or lower it by removing portions. I found two inches lower than 1.5m sounded best.
        
        The other unit is on my equipment rack and right at 1.5m. I use a cardboard tube that is about 3 inches wide and it is placed on top my dac. I needed all the outlets of my Acoustic Revive RTP-6 so I never tried the RR-77 plugged into anything other than the wall outlet near the shelves. The RTP is plugged into a dedicated outlet somewhat further away.
        
        This RTP sounded best at this height. I tried it lower down on various components, where it did not perform as well.
        
        I have not tried alternative ac power sources with the RR-77s, but the RIQ-5010s quartz discs do work well on the one over my equipment rack. They harmed the sound on that between my speakers.
