You would be really impressed with Redbook (PCM) using with todays ideas of I/V (current to voltage) conversion with proper R2R Multibit dacs, as they are "bit perfect" for PCM conversion.
Instead of using Delta Sigma based convertors in most of todays dacs that are used for dsd, then try to do Redbook replay which can only give an approximation, and is not "bit perfect" .
