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


This is a set of adhesive-backed thin plastic pieces that one attaches to one’s transport or player disc tray. The disk rests on them during non-spin mode, but presumably don’t touch the applied thin pieces during playback mode. The company says the new Dark Matter pieces reduces background scattered light from reaching the photodetector, thereby improving performance. 

Anyone tried this product? Please specify transport or player if you have and your impressions.

Bad behavior is bad behavior. Most will and should give benefit of the doubt and accept apologies for bad behavior if offered. Otherwise if it walks like a duck.......

Being funny in the process does not transform dishonesty and contempt into something acceptable. It is just a further form of dishonesty and contempt.

Sorry not buying it.

celander OP890 posts02-11-2019 2:57pmYeah, I worry about using these thingies in a magnetically-clamped top-loader set up. Seems like doom and gloom would arise. This sort of post should cause Geoff to arise and speak about the perils.

>>>You worry too much. NDM is not magnetic. Why would you think it was? Fear of the unknown? Besides, don’t you think a magnetically clamping device is inherently a very bad idea. Hel-loo! NDM is suitable for all CD, DVD, SACD, BLU RAY players with trays or top loaders. I’m not trying to set the world on fire, just start a flame in a few hearts.

This isn’t the end of the story because what I was missing several years ago is something I have always made a part of my life’s work but somehow wasn’t able to read between the lines because I was trying to understand two people in particular through my eyes instead of theirs. My moto is "everything affects everything else" and as much as I understood this with Tuning in the case of Geoff and May I wasn’t grasping this humanly. On one side I was faithful to both of them and on my own did the experiments they suggested. When I was asked about the results I gave a faithful account. When not asked I didn’t volunteer but still did the testing. I did the listening tests because it’s important to me to be in the know. I don’t necessarily care about someone else’s physics...

>>>>>>It may may amuse you to know, I don’t know, maybe it will surprise you or even shock you, but back in those halcyon days over on Stereophile whenever May sat at her computer composing her posts Peter Belt was sitting right next to her. May is like an animal when she gets going. You were lucky to come out of it in one piece. 🐥

Hi Geoff

I think it was a big waste of time for May cause like I said on that forum I didn’t know who she, you and Peter were. I got to know you guys through those posts and then the research I did by looking you guys up, and then all the emails I started getting. It was after that folks started telling me that I had listened to your products in their systems. That wasn’t unusual for me, cause I kind of live in my own world and have never really paid attention to who I was going to be working with on any given day. It’s not me being rude just very intense when I’m doing something, and I don’t get outside of that bubble. I probably don’t know 95% of the people I have ever worked with. That’s just how I’m wired. Like now when you and I are talking by PM, that’s how I am. When you give me a task to do I’m all over it. I haven’t even gone to bed for two days cause I’m working on testing things here and making testing templates to do stuff. If I have a question I’m going to ask cause when I’m working on NDM for example, I’m not the boss you are.

There are so many variables in testing something that I’m not down with is the quick change because I have learned that all of us see change and our first reaction is that we focus on an instant glance of the immediate. Something new is sticking out and that’s what we see until the rest starts to fill in the blanks. I work the other way around. I make that stage as big as it can get and then I look into the change within the context of that space. That’s probably where my testing is different from most. Most are doing their testing with built in limitations, like chassis, dampening, shielding and mass. I’m starting with a huge soundstage in an environment that is casting a stage that goes way behind me as well as in front, to the sides and up and down. In fact I don’t do my testing till the stage is equal distance in all directions. It’s super extreme nearfield. I’m almost dead even with the speakers plane. When I then install whatever it is that I am testing I can hear the stage grow or squeeze, get phazy or glow, fill out or collapse in, full range or tonally imbalanced. Basically a bunch of different cues that are similar to headphones only much bigger and with more feeling and more layering or fill. Plus I can hear if the image gets stuck in my head or if I can spin around and get the image from any direction. I can also check Pressure Zone inflation or deflation, all kinds of stuff. So whereas most folks are doing their listening test from their regular listening position, way before I get to that there’s other tests to do first. I should also include that I do settling tests.

I came to Stereophile the same way as I’m coming here with one difference. On Stereophile I didn’t know I wasn’t going to be able to be myself, I was trolled relentlessly. On here I jumped in with a thread that took on the trolling right up front. I also said I was here to talk based on my walk. Something I always do in this industry with the exception of what happened on Stereophile. I should have just backed out and moved on, instead of trying to find common ground with folks who didn’t want it. I think it was JAs fault more than anyone else. But it was my inexperience in a forum style I had never done before and frankly am not equipped to take on. It was like throwing a piece of meat to the wolves. I had no business being a part of it.

"come out of it in one piece"? I certainly came out of it changed, and sadly not for the better. Some of the innocence and respect I had for the hobby was taken from me.

anyway now I’m rambling

Peter Belt passed away almost two years to the day at the age of 87. Both Peter and May are the nicest most generous people you ever want to meet. There is one thing though, they are quite confident and not at all shy when arguing sound and audio.  Peter Belt was more like Michael Green than one would imagine since before he got involved with things that go bump in the hight he was a designer in the high end audio industry in UK, in particular ortho something speakers. They were both most generous in allowing me to use their ideas many times. I am probably their biggest fan, in fact I’m quite sure of that. There’s a whole other world, waiting out there. A world perhaps best suited to the more adventurous audiophile. 😛 The last time I looked Peter Belt’s Cream Electret and Silver Rainbow Foils were on Stereophile’s Recommended Components.

CD diode lasers are about 780 nm which is in the infrared and is not visible. Our vision falls off greater than about 633 nm or so. Cheaper, more recently developed 405 nm diode lasers in the violet allowed development of blueray. DVD is 650 nm or visible red. The shorter the wavelength, the more data you can fit onto a disc because the features can be made smaller.
That’s very good, stevecham. But why is the sky blue? If our vision falls off after 625 nm how can 650 nm be visible red? 

Pop quiz: what color is a Blu Ray laser?

part 2: what’s the complementary (absorbing) color for the Blu Ray laser scattered light? 
"Pop quiz: what color is a Blu Ray laser?"

It depends on temperature of the environment and an individual’s perception of colors.


What is my prize?

I totally get it. You’re tone deaf AND color blind. But you’re probably lucky in love. 🥰

Color is your perception, not the absolute value. You also forgot that I may have problems with temperature sensitivity.


I am still waiting to find out what my prize for answering pop quiz correctly is.

Geoff wrote “>>>You worry too much. NDM is not magnetic. Why would you think it was? Fear of the unknown?”

Did I say that your adhesive plastic thingies were magnetic? Seriously? (smh)

My fear is having my CD’s torn up by contacting cheap adhesive plastic pieces in a top loader platform due to a magnetic clamp being on top of the CD. Fear of the unknown is not a fear. Fear of the realistically possible is however. 
Let me ask you straight up, glubson. Have you been dipping into the brownies again? 
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.
"...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!

geoffkait,


I do not like brownies. Too simple of a taste, I would say.

I answered your pop quiz correctly. What is the prize?

Not to worry. I wouldn’t have sold it to you anyway. Have a nice day.
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
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
I may have to get a kit for my OPPO now too.
Nice review David.

And a great movie! 
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
georgehifi,

Are you saying that fuses are not directional?

geoffkait,

quick, explain to the man.....what you could not to the rest of us.
Folks, enjoy the thread for as long as it lasts. I’ve gotten my Q’s addressed, including some snarky replies from the manufacturer.

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.

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

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. 
Geoff, thanks for sharing your link to the NDM white paper. Most interesting read that makes a lot of sense.
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
Gosh, folks down in the Pacific islands sure are superstitious, Andy.
Thanks David for your review. I plan to try it soon in my EVS modded Oppo 205. 
Yeah, I admit that there seems a lot of merit to this kit after having read additional info from Geoff’s website. 
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.

Hi George

"Hey he sees it, if it fits, and it’s ok for even a child to see/read it, then why not.

Have you reviewed Geoff's product yet?

MG

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

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

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.
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).
