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.

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.
