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.

Reading comprehension is helpful; believing what one can Google is not helpful. Go look at a UV-Vis absorption spectrum for phytochromes. Then re-read my post.

Hi All

part one NDM

A while ago Geoff was kind enough to send me some NDM for review. I was excited to get the product as this was the first review item I ever received from Geoff directly. Other product of his have been in some of the systems of some of my clients and I got to preview them there. I didn’t know who Geoff was when I previewed some of his goods before, so this time around was more meaningful.

First off I want to start by saying, I would have needed about 10 kits to do a full reviewing.

I think the main question on everyone’s mind is "does this work"? And from this empirical tester the answer is yes. Does the product work the way Geoff describes it working? I really don’t care. I deal with so many audiophile-ish descriptions that come from directly quoting wiki or other internet sites that for me actually doing for yourself makes things more practically acceptable and less fluff. I am hands and ears on and the rest of this stuff is being studied by professionals in labs with qualified testing equipment and years of experience, so they to me are the go to folks for the technical explanation side of things. Audiophiles sitting at their test benches are cute, but that’s about it when it comes to the real deal in tech talk.

I’m breaking this up in several posts.

As a guy having a Ph.D. in Biophysics from Harvard, I find it nice being marginalized by one who is not.
And you have the attitude to go with it. 😁

You mean the absorption spectrum for phytochrome on this page?
