The Denafrips Pontus II 12Th-1 NOS R2R balanced dual-mono DAC represents an excellent high-end digital-to-analog conversion solution, offering ececption sound performance. Here, each channel is equipped with an independent high-speed FPGA to facilitate digital signal decoding by means of 4 sets of high-precision R-2R networks. The choice of such a design results in very low linearity error, high decoding speed and low digital noise, not only to ensure that the audio signal has very low distortion, but also to ensure very low background noise. All digital inputs are buffered in FIFO memory and reclocked by integrated femtosecond oscillators. Excellent jitter rejection makes the Denafrips Pontus II 12Th-1 much less dependent on the quality of the source equipment's clock.
