Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

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

Cheers George

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.

That’s a deep subject.

What, he asked of Audiogon's reigning physicist, is a "Quantum well"?

@celander, so what are your listening impressions??

So I received the kit in the mail over the weekend. I was going to initially use the kit with my Oppo Blu-ray SE-83 front-loader player. I bit the bullet and applied the kit to my Jay’s Audio CDT2 MK2 top-loader CD transport instead. The listening sessions are ongoing.

Well, they are directional, aren't they? Top surface absorbs; bottom surface does not. Lol

Not directional? That is very suspicious.

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!

The active NDM material, the small Super-thin squares, is not adhesive so Super-thin double-sided adhesive is necessary to attach the NDM to the upper surface of the CD tray. Total thickness NDM + double-sided adhesive less than 1/32”. Bingo Bango Bongo!

Why is it double sided adhesive??

glupson ROFLMAO, but NDM is the real deal

"Geoff questioned my first language as English at one time..."

geoffkait questions many things, except his own claims. You could say he is a pseudo-skeptic.

Toot-toot!

Everything you need to know about NDM is on my main web page, top of the page. 

In any event (yeah, I know, a pathetically uncreative choice of words for a follow-up post), his A’Gon ad ordering platform works like a charm. I plugged in an order to try with my Oppo SE-83 Blu-ray player (front loader).

Looks like a simple misdirect to an incorrect webpage link that’s an easy fix. In any event, the website instructions request the potential buyer directly contact Geoff with a list of desired products so Geoff can generate a PP request for payment.

I suspect the word Earth should be capitalized, yes?

Geoff questioned my first language as English at one time. I wonder if his first planet is earth.

Love his website! Brilliant! His products work and he is creative and quite funny. 

@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!

tuffy72561:
I look forward to your impressions of the Dark Matter treatment in your already much improved Oppo 205. It will be interesting  for sure.
David Pritchard

Yeah, I admit that there seems a lot of merit to this kit after having read additional info from Geoff’s website. 

Thanks David for your review. I plan to try it soon in my EVS modded Oppo 205. 

Gosh, folks down in the Pacific islands sure are superstitious, Andy.

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

Geoff, thanks for sharing your link to the NDM white paper. Most interesting read that makes a lot of sense.

I know it’s challenging for some to properly spell a user name.  But when one does it repeatedly with different misspellings, I do start to wonder if the intent is to be mean. 

celander OP904 posts02-16-2019 11:18pmThe difference George is that he doesn’t believe in his own snake oil.

“The trick, colander, is not minding that it hurts.” - Lawrence if Arabia 🐪

Bit of advice George.

Try not being so darn testy in your posts and they might last longer.

I truly miss reading them, hate to see just a bunch of removed posts.

Breaking Gnus! 🐂 🐂 🐂. 

New Dark Matter White Paper now available!

Thanks for your reply!

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.

Folks, enjoy the thread for as long as it lasts. I’ve gotten my Q’s addressed, including some snarky replies from the manufacturer. 

The difference George is that he doesn’t believe in his own snake oil. 

georgehifi,

Are you saying that fuses are not directional?

geoffkait,

quick, explain to the man.....what you could not to the rest of us.

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 may have to get a kit for my OPPO now too.
Nice review David.

And a great movie! 

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

Not to worry. I wouldn’t have sold it to you anyway. Have a nice day.

Geoff, Thanks for your response. I’ll pass on this tweak. 

"...the NDM will eat your CDs, destroy the magnetic clamp and ignite your transport, causing it to explode in a massive radioactive fireball."

Do not use it!

calabder, yes, the NDM will eat your CDs, destroy the magnetic clamp and ignite your transport, causing it to explode in a massive radioactive fireball. So, yes, you’re right to worry.
