What is the advantage of R2R-based DACs for CD playback, you ask?Nodicnorm is correct, this is from MoJo Music which gives you the reason why a R2R Multibit coverters are better to do RedBook (pcm) with, than a dsd (delta sigma converter.
"When a PCM file is played on a DSD or Bit Stream (Delta Sigma) converter, the DAC chip has to convert the PCM to DSD in real time. This is one of the major reasons people claim DSD sounds better than PCM, when in fact, it is just that the chip in most modern single-bit (Delta Sigma) DACs do a poor job of decoding PCM."
The reason why I said to the OP to get the earlier ML no.39 than the later ML 390s. Also the Linn CD12 and Naim CD555 are great older units for RedBook replay. All these are still very pricey on the used market for a good un-molested one..
