Another Discrete R2R Multibit Dac that can do DSD, again from the land of the Great Wall

George I'm curious, what would be your preferred method of I/V  and output stage circuit if you were to design a DAC?
Charles,

Thanks for your informed response George, I appreciate it. My DAC takes the approach of a single resistor for I/V conversation. It is but only one of several suitable methods but it surely sounds very good as implemented.  I will read the thread you cite.
