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’m well aware. 

I’m surprised that Tweak1 didn’t make the first post here. He’s posted the identical rave posts on several other threads.

@elizabeth  I tried the same refrig magnets and yes they do work, maybe not to the effect the ones selling for $600 do (but don't know since I've not compared) but others should try this tweek out and let all know their experience.
