A cool-running, 90 per cent efficient Class D design, the Amp 10 claims 100 Watts per channel into 8 Ohms which climbs to 150 Watts into 4 Ohms. The power amplifier is a fully balanced design with an H-bridged output. The single ended input is transferred to a balanced signal inside that feeds through to the power stage. The filter stage is made with high-power, shielded inductors and automobile-spec capacitors.
