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

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.

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.

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.

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.

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!

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

OK done.  Does that make me a bad person?

You don't say!

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

Celander is Geoff? Interesting....

It appears the Dark Matter may absorb one’s senses of wonder and  humor as well. Tricky stuff!

It appears Geoffy Downer is off his meds again today. Or maybe got some dark matter in there where it does not belong? Lighten up! Pun intended.

Breaking news!   The un-seeable has been seen!   The Darkest Matter Out There!!!!

Mazel Tov Geoff! It only took over 14000 posts. Is that some kind of record?

No.  Dark Matter rocks.  Much better than the competition:  plastic.  LOL

Plastic?

Needs some marketing work.....

There is no doubt that changing the amount of light detected by the sensor can affect the sensor's output.

I'll leave it up to the tweakers so inclined to determine what works best for them.  If Geoff's approach floats their boat, they might want to also consider a teleportation tweak or two, if still available!  
  

Glupson,

I wouldn’t worry about it.

Geoff may be a little behind the times with his magic but seems to be fine with that.

Yes there are a lot of straggler lasers out there that need to be focused....

Mail order physics + mail order products = match made in heaven for sure....

Could be.  

I just took it though.   See ya.   Your remaining captive audience of 1 awaits.....

It's your product.   Sounds like you don't understand it either.

Here’s another pop quiz. a) Given the speed of light and the small quarters inside a CD player compartment, what difference does it make if the light, regardless of wavelength is scattered or not ? The sensor detects the light at the same time whether scattered, reflected or direct.

b) Also black matter being black only means it absorbs the light we can see, just like other black things. That alone provides no evidence that either IR or UV wavelengths are absorbed. Even if it was proven to absorb IR, and other black things not, it would not seem to matter given point a).

BTW water absorbs IR frequencies. You might moisten some white matter, stick it in there, and put black matter to shame.

Not to mention that unless the compartment is totally sealed in material absorbing the laser frequencies, some nasty light might still get reflected!!!! Watch out!!

BTW, anyone know the actual EM frequency range that sensors used in CD players actually detect? That would be a good start to know what will be most effective in absorbing the light, not that it is likely to matter....

BTW rumor also has it windmills cause cancer.   Go Figure!

"

black

1. (of an object) Absorbing all light and reflecting none; dark and hueless."

GK what makes your Dark Matter better than other black things one might put in there or in some cases of good design are probably already there to start? Every CD tray I recall has been black to start with, so a good start there.....


Just wonderin....

I’ll go out on a limb here and say of all the Machina Dynamica products out there, the dark matter and springs have the best chance of actually doing something other than playing with your mind. But I must qualify that by saying the MD bar in general is set pretty low.

Also, even for those, if one is impressed, they might try rolling their own and comparing just for kicks or maybe even to save a few bucks.

Also if the MD products do not work, one is only set back 2 or three digits max, not too bad on the grand scale of all things high end audio.

Personally, I will pass. No offense.

Bad behavior is bad behavior. Most will and should give benefit of the doubt and accept apologies for bad behavior if offered. Otherwise if it walks like a duck.......

Being funny in the process does not transform dishonesty and contempt into something acceptable. It is just a further form of dishonesty and contempt. 

Sorry not buying it.
