The Pioneer BDR-S03J Blu-ray burner appears to be a fantastic CD-R burner as well. Check out this quality scan from a disc it burned:
Pay attention to the level of jitter, or lack thereof! I don't know of many drives that can burn with such a low level of jitter, and that is usually the deciding factor in whether the disc will play in old CD players or not. The BDR-S03J was running the newly released 1.1 firmware and the disc burned at 16x.
This may be kind of old school, but still good information. Hopefully I'm not too far out of the loop regarding what is and isn't a high quality CD burn.
