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.

You don't say!

Do you have a hifi tweak to correct for those gravitational waves too?

Do you have a hifi tweak to correct for those gravitational waves too?

>>>Funny you should ask, Moops. Well, not funny like a clown 🤡. But as it turns out, there are some audiophile tweaks that correct for or take advantage of gravitational forces, (which we now understand to actually be ripples in spacetime. Pendulum type vibration isolators - like my Nimbus Sub-Hertz Platform of yore - employ the force of gravity as a means to damp the pendulum motion (albeit rather small) of the isolator, LIGO project to detect gravity waves also employed a similar but much more complex pendulum isolator as part of its comprehensive program of seismic isolation. But more to your snarky question, there are several PWB Electronics tweaks that address the deleterious effects of gravity on sound. If I recall correctly, the coloring of the inner edge of CDs BLACK has something to do with gravity, as well as painting the outer edge of the CD VIOLET. Obviously the color violet is unrelated to either visible red light or invisible infrared light. These treated (I.e., programmed) BLACK PEN and VIOLET PEN tweaks also apply to LPs. I’m going out on a limb here, and speculating the BLACK PEN around the inner edge of the CD is in a sense replicating a BLACK HOLE in the center of a galaxy. But that’s pure speculation.
"...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.
The most obvious use of springs from a historical perspective was when Kubrick was filming the faked Moon landing on a movie set outside London somewhere as a favor to NASA, under extreme pressure to make a “show of force” to the Ruskies that particular day. Springs on the shoes of the actors who played the astronauts, at least one borrowed from the making of 2001 A Space Odyssey just prior, possibly Kier Dullea, made it appear they were walking on a low-gravity lunar surface. Kubrick stated later in an interview he got the idea from watching Roadrunner cartoons. A side note: it was Kubrick’s wife who came up with the line, “One small step for man, one giant step for mankind.”
I just looked up Stanley Kubrick and his involvement on the Moon. Not that interesting.

However, there was a link to a much more audiophile-related and important topic. The moon is only four miles away from Earth. It is closer than some neighborhood grocery stores.

That changes the whole gravitational waves, black holes, and what not theories. Even directionality may be affected.

In practice, if the spring is appropriate and we, one by one please, get free from Earth’s gravitational forces, next AXPONA could be on the Moon.
I always assumed AXPONA was where all the losers from CES went to try to recover their losses. In fact I was told AXPONA is CES spelled backwards. 
Anybody else tried NDM? Please chime in now before this thread loses all relevancy..
We’re presently waiting for at least two folks to file their reports, the second person is apparently the victim of some kind of USPS mail Delivery fiasco underway in the great state of Florida. In the meantime, I’m perfectly willing to provide my own results, you know, if things get a little dull.
If I have been keeping track correctly, everybody who reported using this NDM did report that it works. It has been only a few reporters, but they were positive about it.

Even with such a small, and easily biased for whatever reason, sample, I would say it is worth trying for intended application. That takes into consideration relatively low price of the experiment.

The thread has been a success. It answered the question "does it work" sufficiently while providing entertainment with theories "why it works".


I hate to be a spoil sport but that’s actually untrue. Can I say that?
@geoff 

I was wondering what took you so long.
  
Three days ago I replaced my PS AUdio Stellar set (all 3 of which was resting on your Promethean Springs), with my Audio Alchemy DPA- 1 and DDP-1 + PS 5. I decided to place them directly on the John Boos boards. The music was very warm tube sounding, rolled off. 

Yesterday, one by one, I put a set of P springs under them. One  by one the sound became more open and lively. Another amazing product
That people report it works? I stand corrected. I was not that careful in following the thread but got an overall impression that reporters were positive about it.

Ok, then, NDM does not work despite my impression that people praised it.
@celander 

I believe you have a created a self driving monster here that is destined to feed on itself continuously  until the end of time.

Or when a black hole swallows us all up, whichever comes first...…..
At this point we really have to consider what kind of world we’re going to leave to Keith Richards.
Fact is my hifis all sound peachy keen, no serious issues to address at present.   So I come to threads like this just looking for problems but gotta say luckily the coast is clear.   Can't fight Mother Nature.   You can try but she always wins.   That includes gravity fields.  

Ironically, I do not even play CDs anymore.  I stream which is a major step forward!   I  do rip CDs but that software does error checking and rereads as needed and rip speeds are still good.   

Someone should test ripping  a CD with error checking, with and without Dark Matter.  If the CD consistently rips significantly faster with Dark Matter, there would be numbers to back up claims of better sound.

Cheers!
Is ripping with error checking making much difference? Is there a significant difference in ripping programs?

I have tried only iTunes and dBPoweramp and cannot hear difference with any consistency.
Glupson.

Heck yes is the answer imho.

I used to use dbpoweramp and even windows media Center.

Now I use jrivermedia and I feel it is superior for rip quality compared to either of the aforementioned programs.

And as for ease of use it is not even a contest......
Glupson,

Yes. Like all software, no two programs do things exactly the same way. There are only a few ways to do it well and many ways to do it poorly.

I use DBpoweramp. CDs can take much longer to rip with perfect rip where no errors are allowed.

if you allow errors and there are, DBPoweramp will complete the track rip faster but show that the track was not ripped perfectly. It determines what the right rip is by comparing to a database of other rips. Actual rip time will still vary with low quality, defective or damaged disks taking much longer still to rip than high quality ones of similar play time.

I find in very few cases where dbpoweramp indicates errors in teh rip are those errors clearly audible. They tend to be minor in most cases, but I have had some very bad CDs I have ripped and allowed errors with just to be able to get a rip at all and you can sometimes hear some defects in teh sound clearly. Not very often in practice though.
Thanks guys,

I was secretly hoping it would be "more or less the same" so I never ever get tempted to redo all my CDs. Appropriate metadata and all that, I need another lifetime.

I noticed people praise jRiver often, I am not sure if it was ripping or other things, so I guess I should give it a try.

Thanks again.

Back to black holes and future of the world.
Please advise if and when anyone tries ripping using NDM. Much obliged.
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.

Mapman

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......

”If I could explain it to the average Joe Blow they wouldn’t have given me the Nobel prize.”
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.
OMG, consider the ramifications of  mapman’s suggestion: 

Geoff sends NDM sample off to Stereophile for review —> Stereophile gives NDM a rave review —> Geoff slammed with NDM orders —> Geoff sets up his own NDM blog/vlog site to support the NDM sales —> Geoff never posts on the A’gon forums again. [Insert “My Pillow” commercial background music here..]

We will miss ya, ol’ buddy! 😥
Is Stereophile still in print? That is so 15th century.

After this thread, I am tempted to order this NDM.
celander OP
As impossible as it might sound, this thread has made me less intelligent.

+1
@celander I’ve been no. 1 here for ten years. I kind of doubt I’ll be going anywhere, ol buddy.
I may need to order a second NDM kit before the crush of new orders hits Geoff’s site. (And before the obligatory price increase hits the product.)
☝🏻 +1 for clarity, @glupson

This thread leads “recent activity” in the forum!

I didn’t realize it’s 2022 AD. 
Not to be too picky, but to make sure everything is clear. I went to the audiogon page where NDM is sold and found this description which brings me back to my question from a couple of days ago...

"...for reducing background scattered laser light, thereby improving performance for CD and ALL digital players."
Many digital players do not operate with laser. Would this work on SSD? If yes, ALL is well. If not, maybe a rewrite of the description is in order.
I may have to come up with my own competing product that will be much better and darker and also matter way more if turns out this is a big money maker.   My Funky Fuses will have to go on the back burner.
"I didn’t realize it’s 2022 AD."
Time flies when you are having fun, with geoffkait.

Now, let's see how that flying time impacts our perception of sound and black holes. Einstein, where did you go?
