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.

Ignorance that borders on stupidity never ceases to amaze me, especially in hi-end audio

Arguing against when it is clear noone of those arguing plunked down $40 to see/hear, when there is nothing that cna be purchased to improve hi-end for $40, points to thr futility and stupidity of those who think they have a clue. 

I for one am thankful for Geoff's willingness to struggle on in the face of such abject stupidity  
Huh? Call me stupid, but I have no idea what you are talking about.

I bought one of these kits, seeing no harm in trying something so inexpensive that had the potential to improve SQ of my system. Not many tweaks can bring about such improvement for the money expended. So the risk/reward ratio is very high. And if one does not find it to "work" to his/her satisfaction, then it’s not a great financial loss.

But any modification that affects signal processing at the very beginning point of a given source is something that should not be ignored. And the inexpensive cost of the kit makes the decision a low-barrier no-brainer.
Hey, tweak1, let’s try to keep this civil. These outbursts of yours are not constructive.
