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.

Machina Dynamica is the creation of Audiogon's reigning theoretical physicist, (codenamed) geoffkait. Do a web search and you will find the most interesting things. His website http://www.machinadynamica.com/index.html provides a lifetime supply of word salad.

 I know the guy and he's a regular at several hi-fi type forums I visit. He got so sick of seeing BS audio products being sold to the gullible that he created these bogus products as a joke.


We report. You decide. DYODD.
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. 
All the CD player trays I have seen are already black. They sound GREAT. I don't need to make the tray blacker! My favorite new crazy thing to do is place a refrigerator white board. the sort with a flexible magnetic backing UNDER the CD player. So the magnetic mat is about a half inch below the player. The mat on the shelf under the player's feet. Works. blacker background. better detail.   (not stuck on top, not good)     
Cost is $10 to $20 off Amazon. And guess what? it it does not work for YOU.. Stick in on your fridge.!  Draw smiley faces..
Maybe I need to start my own company. Sell the $10 to $20 device for $599. Claim it has been treated with quantum whatever. "Electratomically-molifigrated" with an ultraviolet ray. derived from mini artificial atoms being made into black holes. I bet ten times more folks would try it than saying it is a fridge magnet costing $10 to $20. and from Amazon. LOL
@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.
