After doing a lot of searching and even emailing the author of the whitepaper mentioned in the other thread, I haven't been able to find anything mentioned about black cd's being any different save for the black scratch resistant coating. (There is some mention about black cd's designed for playstations which have a difficult time reading standard cd's, etc) Besides, that whitepaper on the black cd's is a little too black and white for me (heh) hinting that the black cd's are better but without regard to differences amongst brands, etc.
I also find it perplexing that there's so little information available about the differences between cd brands... I mean, hell, we've already outlined our experiences good and bad between brands (mainly on the other thread), yet nobody who gets paid to review audio equipment seems too interested in the quality of the source.

In that regard, I'm with ehider. What's that old saying about the baby and the bathwater???
CD's are cheap compared to other formats of days gone by. I don't mind spending a little extra for the best. Mitsui definitely sounds interesting, but even still their lineup has me confused. Which to try? Silver, Gold, Gold Audio, Silver Audio, etc. What are the differences? Am I too dumb for these manufacturers to give me a shot at an explanation?
Then there's the burner. I'm fortunate to find that my Yamaha CRW2200E has a firmware upgrade for their Audio Master Quality Recording as does Nero with software, but just try and find any explanation from either Yamaha or Nero explaining exactly what it does differently. So far, I'm guessing the burn speed to be about 4X, but who knows. And, if I'm going to this much trouble to create a copy of my existing cd library (hundreds of cd's), would it behoove me to take the drive out of the noisy cpu chassis and isolate it or put a brick on it? It's certainly not too much trouble, but my point is that trying to find logical information regarding optimal cd burning is weak... certainly when compared to discussions of high-end audio componentry and all the nuances there.
Maybe one of youz out there can enlighten me a bit!
