Can you please elaborate on ‘best DCS and MSB’ since they have different tiers of reference. I would like to know which models you’ve tried that were bested by K-01xd?Depends also on what your playing, streamed DSD the DCS and your Esoteric would be the one to go for being bitstream (delta sigma) based dacs.
But if you use PCM RedBook 16/44 24/96 or DXD then "bit perfect conversion" of R2R Multibit like the MSB would be the one to go for. As delta sigma dacs can only give a "facsimile conversion" of PCM RedBook 16/44 24/96 or DXD
