Yep..my kid is cute, too. And I’m just trying to be objective here.
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.

From what I can tell so far with feedback from customers of NEW DARK MATTER and I am trying to resist being too judgmental those customers with good systems hear the full glory whilst those with mediocre systems or systems with mistakes in them get negative or tepid results. NDM seems to very good at distinguishing between the advanced audiophile and the plug and play type. Kind of a smart tweak, as it were. I have a rather good population of customers to analyze now so I don’t think I’m overstating this. I’m just trying to be objective here. NDM is certainly no panacea. Or a pancreas for that matter. |
mapman 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. >>>>>I hate to judge before all the facts are in but it appears my explanation of how New Dark Matter works didn’t work on you. No biggie. New Dark Matter doesn’t affect the level of direct reflected laser light, only the level of the background scattered light. All CD players, regardless of cost or age, have this problem with scattered light. As do SACD players, DVD players, and Blu Ray players. |

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. |

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.

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. |
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. |
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. |
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! |
