Marantz recommends TDK or Sony on their newer CDB's. I have had the best luck with these brands. BAD luck with Maxell, Memorex, etc.
Marantz recommends Mitsui Gold for their older CDB. I was originaly using Mitsui but had some read erors and ruined discs because the Marantz would crash between tracks when burning CDR's.
This is because the Mitsui's have much tighter tolerances on their burning tracks (the concept is correct even if my explanation isn't) and unless you have a very accurate laser placement there can be problems.
