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.

"...there are some audiophile tweaks that correct for or take advantage of gravitational forces..."
The most common of which are colloquially called "equipment racks" and "speaker stands".

I read more about black holes and related topics in this thread than ever before. Which was not that hard, to be honest.

I am considering what the effects of gravitational waves might be on my listening pleasure..... 

OK done.  Does that make me a bad person?

OMG! I forgot the most obvious one. My own Baby Promethean and Super Stiff Springs! It might not be very obvious to the average person but springs are anti gravity devices. It’s a good feeling to get free of gravitational constraints. 🤗 Springs, ironically perhaps, are one way to reduce mass of the audio system. Even Michael Green would have to sign up to that concept. How could he not sign up?

mapman,

It depends how much listening pleasure you get from laying down. As geoffkait points out, springs are very important in whole story. Mattress manufacturers have always been a step ahead of audiophile community.

It is a great feeling to free yourself of gravitational constraints. Every child on the trampoline would gladly attest.

geoffkait,

You actually have something that is called Super Stiff? Good for you, and the end users. Can you elaborate? mapman seems to be interested in all aspects of increasing listening pleasure.
