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 Nº390S yield excellent results by any standards.
However, only those specifications that apply to its actual operation are
included here.
