The Benchmark DAC3-L Reference DAC and Stereo Preamp features an ES9028PRO Converter Chip with quad 32-bit balanced D/A conversion and hybrid gain control technology. Specifications include a sampling frequency of 44.1 to 96 kHz, a signal-to-noise ratio of 128 dB unweighted and 126 dB weighted, a dynamic range of 128 dB unweighted and 126 dB weighted, total harmonic distortion/noise measurements, frequency response data, crosstalk levels, maximum amplitude parameters, inter-channel differential phase, maximum lock time, soft mute functionality, mute features, and de-emphasis settings. The product is designed for high-fidelity audio performance.
