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.

  1. (of an object) Absorbing all light and reflecting none; dark and hueless."

GK what makes your Dark Matter better than other black things one might put in there or in some cases of good design are probably already there to start? Every CD tray I recall has been black to start with, so a good start there.....


Just wonderin....

What method was used to measure/evaluate scattered invisible light inside a working (CD is rotating) CD player before and after application of whatever is being talked about here?

>>>While that’s a true statement as to what NDM is designed/claimed to do it doesn’t answer the question regarding why the color black won’t work just as well.
