Specifications
The correlation between published specifications and sonic quality is unreliable. A list
of numbers reveals virtually nothing. All technical measurements must be subject to
qualitative as well as quantitative interpretation.
Measurements of the Nº32 yield excellent results by any standards. However, only
those specifications that apply to its actual operation are included here.
■ Frequency response:

0.1 dB
RIAA/IEC response +0.1, -0.3 dB
■ Gain: either 40 or 60 dB
■ THD + N:
2V out, 1 kHz test signal, 80 kHz measurement bandwidth less than 0.008%
■ Residual noise
