Overview The Buffalo-II is a 32-bit stereo audio reference DAC module designed for uncompromising audio quality. Based on the ESS Technology ES9018 Sabre Reference chip, the Buffalo32S accepts S/PDIF, PCM, and DSD digital audio signals at sample rates up to 32-bit/400khz. In stereo mode the balanced stereo outputs are made up of four parallel balanced DACs per channel.

Analog Characteristics The Buffalo II does not include an output stage but is designed to mate with the IVY III current to voltage stage. It is not recommended to use the Buffalo II output directly, but it is possible. The output can be used as a voltage source into a high impedance but THD+N will suffer.
