Anyone's thought of building the Soekris DAC? It's a discrete R-2R capable of upto 384 kHz 24 bit.

Reference DAC Module - Discrete R-2R Sign Magnitude 24 bit 384 Khz - diyAudio

Unlike the usual Delta-Sigma DACs, this uses resistive ladders to achieve digital to analog conversion. Pricing for three versions is based on the precision of resistors used. Very interesting.

Which is the DAC chip?ESS9018?

Which is the DAC chip?ESS9018?

No chip. The resistor ladder network performs the D/A conversion. Example of such a DAC is MSB DACs.
