Specifications in Brief

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 SX25 reveal excellent results by any standards. Tested at 115V and 230V after a 10 minute warm up period.
