More InformationDescription:SA-1V2 is a high-performance fully balanced, fully discrete Class A amp/preamp.Support global voltage AC100V-240V, no need to switch.Ultra-low distortion:THD+N -120db @1khz A weighting 20-22khzWhen outputting 50mv at low gain, THD+N still has -96db @1khz A weighting 20-22khzUltra-low noise:At low gain, the bottom noise is 300nv RMS A weighted 20-22khz (tested after amplification by LNA), the direct test value of AP2522 is 0.66uvAt maximum output, SNR and DNR are 147db.Ultra-low distortion, the following figure shows the performance of APX555 test prototype: SA-1 V2 adopts a true four-way fully independent fully discrete Class A amplifier circuit design, pure analog amplifier circuit and pure analog control, without EMI interference caused by digital control, in order to faithfully restore the analog flavor of music.The amplifier circuit adopts the class AB architecture developed by ourselves. The differential input tube adopts ROHM's ultra-low noise audio d
