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.

I speculate one reason why a lot folks gave up on CD and moved to streaming or whatever is that they couldn’t get it right and gave up in frustration, that is if they even tried. Or they like the convenience or whatever of streaming or serving or whatever. I understand that. Untreated CDs played on untreated CD players generally sound thin, bland, compressed, metallic, wiry, irritating, remote, plastic, synthetic, two-dimensional, gloopy, generic, thumpy, hard, sour, rolled off, screechy and like paper mache. I’m not trying to set the world on fire. I just want to start a flame in a few hearts.
GeoffKait you are right for the cd untreated.... I dont doubt that....This is the reason that I am interested in this thread.... I will install in the year to come a cd player for sure … I will try your NDM then....But for lowering the noise level I had my own stones and crystals connected grid on the computer and cables and gear and electrical house cables grid,hence "all is quiet on the western front"...
I understand where you’re coming from but when I say signal to noise ratio I’m referring to the optical SNR and the downstream analog SNR which depends on it. By reducing background stray light in the CD transport you increase optical SNR.

Of course, as you say, all sources of noise and distortion in the system should be controlled and minimized, too. The claimed SNR of 90 dB for CDs is achievable only if the system can handle it which, obviously, in most cases it can’t. That’s why the humble LP or cassette oft sound more dynamic than CD. As for the claimed Dynamic Range of 90 dB, many CDs are overly compressed so there goes your dynamic range spec down the tubes!
It’s now clear to me that one must wake up pretty early to beat Geoff to posting here. 
You have to agree that a lot of what Geoff says , on this subject at least, does make sense.

My NDM treated Pioneer DVD/SACD player does sound fuller and more musical all round.

Now tbh my acquisition of a C.E.C belt drive CD transport sounds even better on Redbook CD and I wish I had some of the NDM left to try in this but alas it all went into the Pioneer and the Sony Discman.

But I was suitably impressed enough to say that I will buy a pack from Geoff when I get round to it.
