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. 🐥
