Fact! They work far better if you stick them on your forehead.

Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?
I’ve detected little change in SQ when the thin NDM discs are applied to the top loader surface. The top loader has nearly a 100% surface of uniform blackish grey color. Only the spindle and laser track cutout (only narrow enough to accommodate the laser assembly track) is “open” area to the inside of the transport. I’ll remove the disks after a few listening sessions to see whether the SQ changed. I strongly suspect these NDM discs will work better at improving SQ for a front loader, as the typical CD tray has a huge cutout upon which the CD sits on the perimeter. I’d imagine all the laser light reflections, deflections and diffractions are escaping though that large cutout gap in the tray and bouncing off interior electronics boards inside the player. I’ll be testing my Oppo front loader Blu-ray player with these NDM discs next. |
A quantum well is a potential well with only discrete energy values. The classic model used to demonstrate a quantum well is to confine particles, which were originally free to move in three dimensions, to two dimensions, by forcing them to occupy a planar region. The effects of quantum confinement take place when the quantum well thickness becomes comparable to the de Broglie wavelength of the carriers (generally electrons and holes), leading to energy levels called "energy subbands", i.e., the carriers can only have discrete energy values. The CD laser is an example of a Quantum well, for which particles are confined in two dimensions. The laser beam is emitted from the open, unconfined dimension when the Quantum well is excited by electrical stimulation. The active ingredient in the Intelligent Chip - Quantum Dots, I.e., “Artificial Atoms,” for which particles are confined in all 3 dimensions to the (nanoscale) de Broglie wavelength. A torrent of Photons is emitted in a chain reaction when the quantum dot is stimulated by external energy such as a laser. |
Indeed the NewDark Matter with the adhesive paper to attach the Squares is super thin and Easy to apply. A 10 minute project at maximum. I continue to be impressed with the improvement after installation that my Oppo 203 DVD player is showing. added bonus- there is no break in time and the Dark Matter Squares are not directional!

@celander For sure GK can be a challenge to deal with at times and he does rub a lot of people the wrong way but that's his nature here. Now George will say it's the same old group of gullible snake oilers trying this as those who peddle fuses, mats etc. I would agree that some are the same members but for a total different reason. More its the same group of people because they are open and receptive to the possibility that tweaks can work and are willing to try them. Not every tweak works for every person, I have had some I have returned. Imho the NDM did seem to have an effect in my little battery powered Sony Discman. This had GK previous Turquoise inside which I removed to replace with the NDM. Sometimes you just have to work around GK foibles! |
Try not being so darn testy in your posts and they might last longer. Hey he sees it, if it fits, and it’s ok for even a child to see/read it, then why not. Geoff deserves every bit of criticism, just look at his avatar here and then go to his website, for a real "roll your eyes" moment. Cheers George |

For top loaders: If you don’t have enough clearance for the 1/32” NDM between the data side of the CD and the transport surface above which the disc is spinning there’s something wrong with your CD player. Furthermore, even if there isn’t enough clearance, which I doubt, the NDM will be effective ANYWHERE inside the CD transport compartment since the scattered light is filling up the entire space inside the compartment, lighting it up like a Christmas tree. NDM is not limited to the gap between the disc and the transport. |

This has changed into just another directional fuse thread, with the same bunch of snake-oiler’s making themselves look https://youtu.be/RmyucZa6wD0?t=18 |
I have now put the small squares of the Dark Matter product on the tray of my Oppo 203 DVD player. It was easy to attach the small pieces of film- like materiel with the double sided adhesive paper (very thin) to the top of the black tray. Ten minute project. I watched the same scene from the movie - The Fifth Element where the Diva is singing. I think this scene is a good test of both visual and audio performance. The picture now has more detail and the colors are richer. During motion in the scene, the picture is also improved. The audio dynamics are increased. Final verdict - The Dark Matter Treatment Kit works for my DVD player and is staying in place. David Pritchard |
The Dark Matter treatment kit arrived this week and I look forward to evaluating it's effect on my Oppo Blue Ray 203's picture and audio output. The kit is sold with a 30 day money back policy and return postage is cheap so I think it is a fun experiment! I presently use his Turquoise colored ring on the DVD tray, so it will be interesting to compare no treatment, Turquoise Ring, and Dark Matter squares. David Pritchard |
