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 see what you mean. Nevertheless NDM is superior to phytochrome and IR and UV dyes because it NDM absorbs at all (rpt all) visible and all invisible wavelengths.

@michaelgreenaudio- Mike, you should have just stopped at part one. You said it works and you don’t care how it works. Anything else past that (like your part two and three) is just a segue into you long windedly talking about yourself, what your about, and pretty much a thread hijacking.

NDM part 4

Practical Application

From what I have discovered so far NDM is not a one size fits all tweak nor is it an exclusive tweak. At first I tried one CDP type to experiment with, so I could find a pattern of placement that worked best for me. I went from full size down to 1/8" slices before I found the most entertaining setting. On the down side NDM for me took away from the fullest of soundstaging, on the up side you're able to play with some soundstage tightening. If you're after a lower noise floor and willing to loose some of the stage side this is doable. It has a slightly similar sound to mu-metal transformer shielding. It's a quieter sound, a little too dark for me personally but I know many who like this type of sound, especially if they have unruly CD problems. It's a musical taste that bigger soundstagers may not be crazy about, but for the mid size stage guy who is finding CDs bright this is a possible go to.

I will be doing more on NDM if I get more but have run out of usable pieces. Running out of pieces I did go get some similar looking plastic and found the performance to be along the same line, so maybe Geoff will be offering several types for different types of performance wants.

Hi carp, thanks for your advice but I prefer doing my reporting my way. However I won’t make anymore comments unless the OP asks for them in the future on his thread.

However might I suggest that you've just limited the positive reporting on Geoff's product that I was just getting started on.

I never advise anyone on how to do their reporting. Something called a first amendment (to the extent moderated by the powers that be here) is in play..
