Specifications In Brief
The 750 specifications are detailed in brief and then subsequently in more detail. In the detailed version, we attempt to explain the significance of each specification.
The correlation between published specifications and sonic quality can be unreliable. A list of numbers reveals virtually nothing. All technical measurements must be subject to qualitative as well as quantitative interpretation. Measurements of the 750 reveal excellent results by any standards. Tested at 115V and 230V after a 10 minute warm up period.
