VA Series
Technical Specs
Where it is not specified ratings are for all models:

CONTINUOUS OUTPUT NOMINAL POWER *:
[both ch. driven from 20 hz to 20 Khz; THD < 0.1%]
*
These power levels have been measured by very tight and severe Joule's Law phisical effects, it is not possible to directly compare these values with other brand amps declared values.
