Classic AMP

MSRP not recorded

The Nagra Classic AMP is a high-power solid-state stereo amplifier made by Nagra. It operates in pure Class A over a broad power range and in Class AB beyond that, with output stages based on tandem MOSFET transistors, an overdimensioned transformer, diode-bridge power supply, PFC decoupling, and 300,000 μF of filtering capacitance. It delivers 100 W RMS per channel into 8 Ω, supports balanced and unbalanced inputs, bridged operation at 200 W into 4 Ω, and bi-amplification.
