[sdiy] Re: Inexpensive 16 bit DAC?

[Mete BALCI]

20-bit DAC in D-50, I dont know that. What is that for
? Do you think it is really needed or just for
marketing purpose ?

As I know D-50 is an hybrid (analog filters) with
16-bit samples, does it use its DAC immediately after
the pcm wave generation ? If so, why is there a need
for 20-bit DAC for 16-bit samples ? Does its internal
processing is greater than 16-bit ?
