SU-9n is also equipped with ESS Sabre ES9038Pro chip but combined with high-performance power supply chip ES9311. SU-9n has a total harmonic distortion (THD+N) down to 0.00006%, its signal-to-noise and distortion ratio (SINAD) is at an even 130 dB for XLR. It adopts a CK-02 clock processing circuit to achieve ultra-low clock jitter, and with the DPLL setting, it could avoid the sound interruption when the clock stability of the input signal is not good.
