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.

One serious flaw with 'modern society' is the one phrase for an entire life's meaning ... disaster. Which is way too many people are pigeon holed as one fragment of a complex life, chosen, almost at random by society, the mob, to completely define a person. The Single News Headline for a lifetime biography.  
Certainly makes decisions easy, everybody you ever meet is turned into a one sentence definition. So for Geoff, this is an easy happening. Folks immediately classify him, ignoring a whole life, for one tiny aspect of his public display. So I say it does not matter what someone says about Geoff. He is just a person. another person with an interesting company, making somewhat crazy products. He is not the product.
Best post ever by Eliz.  Plus infinity to her thoughtful comment.  So true it should sink deeply into each of our minds before posting some of the harsh words I so regularly read here. Best post award!
