SIGNAL/NOISE RATIO

SI-5 Super-T AMP - stock configuration

S/N is very good. The amps have a well earned reputation for a quiet background. Noise is below most CD player thresholds. The peaks seen just to the right of 200 and 2K Hz are measurement artifacts, not noise.
0dB =7.5V RMS for 5066, Fenice, Super-T. 10V RMS for AMP6. Noise is combined amp and PSU noise. See notes.
