Which CD-R best for Audio?

Any mitsui is good, or only the gold?

The best for me so far is memorex black - noticeably better than imation.

All Mitsui (gold and silver)have their own chemical dye that is different from all other CDRs. All other CDRs use the same chemical dye (including the black ones). Good CDRs are made in good factories. Do a web search and you will find info on which factories are good and which brands they make. Some brands are made in multiple factories (good and bad), and some good factories make mutiple brands.

I have used Mitsui silver unbranded and have had no problems. I've burned hundreds of CD's. They aren't the cheapest out there.
