Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

Well, it did make me think about how a laser disk reader works and what effect changes in light levels detected could have.

In the perfect case, the sensor is properly calibrated to detect light levels reflected by its laser from the discs surface perfectly and that light signal is converted to the digital electronic signal and sent downstream perfectly.

Of course nothing is perfect. Each device will vary from that ideal but good devices will do it with some design tolerance that helps assure accurate results.

Also of course performance of all devices declines over time so a 10 year old device no longer functions as well as a new one in most cases.

Now, introduce anything that affects the actual light levels detected by absorbing some of it, and if enough is absorbed, a change in the output should occur and could be audible if large enough.

Regarding Dark Matter there is a chance it could result in less light getting detected like any material that in theory absorbs light at the right wavelengths.

As for how much it actually does or if it does how it sounds, for better or for worse, all bets are still off. Its all just hearsay at this point. It might make a difference at least in some cases, but no way to know. There are a couple of reporters saying it did. So there you go.

Hands up and jonesing up as being one of "those reporters".

I honestly do think it made a difference on both players I installed NDM into.

But what do I know, I am listening to Mamas and Papas so go figure......

GK,

Saying a product of yours "could" make a difference is high praise for Dark Matter compared to most Machina Dynamica offerings. It might even absorb more light or do it more constructively than plastic, who knows?

You gotta take what you can get......

Send some to Stereophile and let them put it through its paces.  Maybe compare it to plastic.   I would appeal to an authority like that in a case like this.

celander,

Do not underestimate yourself. You have enough intelligence left for a few more threads like this. If you want to speed the process up, go back in time to "Talk but not walk" thread and see how quickly your head can get vacuumed. Black holes will seem like carpenters’ workshops after that.

To make it better, this thread, as odd as it may be, is way more useful and challenging than any of the cable threads I have seen. There is even some soft conclusion and agreement about NDM, even from usual skeptics. Try that on a cable thread.
