Your right of course FrankieD!! ...and howw U doin?!!
I was being an SOB smarty with that one word answer. || Trying to get a rise...please forgive me!!!! )
I've posted, in the past, several papers about digital mechanisms and how they are effected by distortions as they read. I don't think it'd be too much of a streatch to say that it's pretty well understood that sonics are impacted by how much a player has to chase the data. That's why there are so many little tweeks out there that probably mostly make at little tiny bit of difference. Trueing up the CD edge, cutting a specific slant, the green coating, the anti wobble/dampening rings. But there are also things that the higher end manufacturers do inside of player mechanisms too with dampening, darkening and so on. If you want to know more, I'd suggest going through a few of the Stereophile reviews of the better players. Down in articles, you can lots of times find little nuggets of information.
The black CD thing has been around for some time. Not a new find. My personal experience with black CD's was I couldn't tell. I have a little analysis program that reads a burned disk and counts errors. It's stunning when you see huge numbers and you can't help but think about all the comments you see about "bit perfect"! In the case of my particular burner, the black ones (Memorex I think, sorry Steve) repeatedly came up with a sizeably worse error count than the same speed, same material burn on regular disks. That could be just a reflection of my particular burner.
When I have a chance, I'll find that analysis program, do a few burns and post some results. It's darn interesting. And maybe we could find that program somewhere for others to download and play with too...
So I guess I'd say that from book learning side it'd seem possible it could have a positive impact, but it didn't happen that I could tell. But I don't discount that some have had more clear gains. Maybe better players than mine....
