Hi all,
due to having found in a thrift an old Pioneer CDP with dual BB PCM58P-K DAC chips, I started taking an interest in different architectures. I know that the PCM58 is a R-2R ladder DAC which some people say is superior to the delta-sigma DACs more commonly used today. This made me look up the chips used in some of my other gear laying around just out of curiosity. One is a HRT MS II which uses a PCM 1794 which is according to TI an "advanced segment" DAC. I am assuming that that is not the same as delta-sigma as TI explicitly lists other chips as delta-sigma. Is that their term for a R-2R ladder or something different yet? If so, can someone please point me to a resource that I could use to learn a little about what that means?
