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 SXH2 reveal excellent results by any standards. Tested at
115V and 230V after a 10 minute warm up period.
