The NOS R2R DAC design with special emphasis on non-oversampling (without digital signal filter or manipulation of any kind) sounds completely different to the same DAC but with digital filtering  or noise-shaping Delta Sigma, digital signal processing (DSP) type (also in form of FPGA) of digital circuit. In the right design, a great R2R DAC … Continue reading Delta Sigma vs Non-oversampling R2R DAC Designs
