In Reply to: DAC's Which Convert PCM to DSD posted by Mikey8811 on March 14, 2016 at 23:50:56:
Hi,
Any DAC or CD Player that uses a Delta Sigma DAC Chip internally converts PCM to single bit (in effect DSD) at a rate of usually something like DSD 128, sometimes even DSD256.
So the list includes anything with Wolfson Micro (yes, that includes certain models of iPhones and iPods), Cirrus Logic (more recent iPhones all use these), Asahi Kasei Micro, Nippon Precision Circuits and recent Analogue Devices Chips. Even many recent TI DAC's are pure Delta Sigma, as are the later Philips/NXP.
Given that Delta Sigma DAC's took over in the early 90's from Multibit it will probably be easier to make a list of DAC's that do not convert PCM to DSD but render it as PCM, than the other way around.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
