Specifications
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. M easurements of the 750 reveal excellent results by any
standards. Tested at 115V and 230V after a 10 minute warm up period.
