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.

The title of that video says...


"...captured by team of Harvard scientists and astronomers"
while the text under the video starts with...


"A global team of astronomers, led by Harvard scientists..."
Are all global astronomers from Harvard?

Is there a description of what "led by" actually means?
Received my NDM from Geoff, thank you. When time permits, I shall install it and share my impression. We now return to our regularly scheduled nonsense...
