BTW, someone on page one mentioned he was using a front loader and was not " clamping ". Front loaders do have a clamping mechanism, fyi. Geoff, udaman ! Enjoy MrD. !
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.

mrdecibel1,345 posts04-03-2019 6:28pmThey should never have discontinued the green pens. Art stores have them. >>>>Green pens, sadly, only address 25% of the stray laser light, the red part. The other 75% is invisible, which is not (rpt not) amenable to the color green or any color. That’s why NDM is such a breakthrough. It absorbs the red part AND the invisible part. Hel-loo! |

My listening evaluations are finished. I’m without words: just let me say this is the greatest improvement in my audio system to date. More so than anything other than exchanging loudspeakers, which is more about flavors than realism. Greater microdynamics, seemingly purer sonics and dimensionality. Geoff, this kit is way too cheap! |

I just heard from customer X who told me his big Acoustats sounded great with 9. His big system, the classified one, has 11. I’m not saying 8 or 12 won’t be just as good. You might try the two new ones farther away from the laser - near the outer boundaries of the transport surface. Since scattered light gets emitted out the outer edge of the CD. |
I didn’t mean to imply 8 or 10 are magic numbers. But I did find out it can be overdone. That discovery was made on a classified system. The moral of the story is more is not better. It’s not necessary to cover the entire tray surface. The NDM is currently going out with 10. Subject to change without notice. Your patience is appreciated. I now think 8-10 is great, less might be equal to or...... I see only 6 squares/rectangles in your photo of the top loader. Am I missing something? |
I now have about 10 days of watching the improved video and hearing the improved audio from my New Dark Matter treated Oppo 203. This is a nice improvement to an already good player. I really think if you system uses CD's or DVD's this is an upgrade worth trying. Ordering a second kit to try on a run of the mill Samsung player. David Pritchard |
thecarpathian172 posts03-02-2019 3:43pm@geoffkait, on my way to Theater Camp this morning, I found myself wondering if the material you use relies on surface plasmon resonances? >>>>>>Hmmmmmm....very interesting. 😳 |
The NDM needs to be close to where all the action is as the objective is to reduce the power of the scattered light inside the transport compartment below the level that can be detected by the photodetector which is 75% of full reflected beam. It’s more straightforward in front loaders because you can see, as you said the NDM is right where all the action is. However I think as anywhere inside the transport compartment should be OK. The entire transport compartment is lit up with scattered light, even though most of it is invisible. |
OP George can get that way at times Not much love lost between George and Geoff here. But GK is a big boy and can stand up for himself quite readily. I would agree that you may find better effect inside a traditional front loader, that large cutout is exactly where I stuck a load of the NDM. Please keep us informed |
