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 Nº383 yield excellent results by any standards. However, only those specifications that apply to its actual operation are included here.
