Integrated amplifier
typical
Among the 59 integrated amplifiers in the catalogue, this one is typical.
A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.
Power amp gain: +29dBu. THD < 0.0004% (class-leading; Jan Ertner design).
Three modes: Integrated / Pre-Power / Pre Mode (disables internal power amp for use as pure preamp).
Assessed against 19 rivals across the sixty systems: 1 head-to-head won, 59 lost.
The dimension the engine names as the weakest link, counted across every head-to-head it lost.
