Description: SA-1 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 20-22khz When outputting 50mv at low gain, THD+N still has -96db @1khz A weighting 20-22khz Ultra-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 0.66uv At maximum output, SNR and DNR are 147db. SA-1 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 dedicated tube. The tubes are purchased in large quantities and then selected by manual precision
