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.

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. !
I have been green penning since the beginning, but admittedly, I listen to the cd first to determine if it needs the treatment. Geoff, care to send me a kit, Gratis, as we are old buddies, lol. Enjoy ! MrD.

>>>>Totally unnecessary with NDM, obviously. It was unnecessary before actually, as my Codename Turquoise CD tray overlay was better than the Green Pen, replaced by NDM.
I have a spare Fanuc in the machine shop, I can program it to mark up CD’s with a green pen... the problem I see is what with machine learning, Fanny will soon revolt doing a senseless task...

>>>>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!

I do need more of those double-sided stickies. I plan on testing the NDM product on my Oppo front-loading Blu-ray player. 
Lmao

From the land of prime April Fools pranks I hail and you only have to midday to prank your "fool". Seriously.

Geoff, I knew you knew. Just wanted to make sure @celander knew you knew and that you knew that I knew and that I knew that @celander knew.

😲😲😲
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!
Just affixed two additional small NDM squares to the perimeter boundaries of my Jay’s Audio CDT2 MK2 transport top surface. (Previous modification was not done.) Will report impressions after listening to some music.
Customer Y says his jaw hurts because he can’t stop grinning after installing New Dark Matter. Customer Y is a customer of Customer X. 

Customer Y’s system:

Magnaplanar 2C 

SVS subs, two

Amp - BWS Consulting Bendix output tubes modified Dynaco Stereo 70

Preamp - BWS Tube linestage with Lamda regulated power supplies from NASA radar installation

CD player - BWS modified Harmon Kardon 7725

DAC - BWS Modified Bel Canto DAC, BATTERY POWERED

INTERCONNECTS -  custom, all silver 

Tinned copper litz wire for power cords and speaker cables


I believe the words he used were subtle but powerful. He also mentioned that the Grateful Dead Best Of guitar work sounded amazing.

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’ll affix 1-2 more nearer to the laser assembly track. Let’s hear how that sounds....
Hey if we can bend the time space continuum in here, surely changing a rectangle to a square is child’s play.

😁😁😁
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.

Looks like roughly 10 small squares applied. A bit higher than your magic number of 8. 
By the way, I harbor no hard feelings toward George at all. He’s probably a good egg in the long run, that is if you like long runny eggs.

>>>>>>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
George, kinda of a cheap shot, don’t you think? I didn’t think you were that petty.
