About the Classic Amp
The Nagra Classic AMP is a purist solid-state stereo amplifier engineered for the highest levels of musical fidelity. It operates in pure class A over a large power band and switches to class AB for higher output. The amplifier features a massive power supply with a 300,000 μF capacitor bank and an overdimensioned transformer for instantaneous transient response. Output stages use tandem MOSFET transistors for exceptional linearity and stability. The front panel includes a traditional Nagra Modulometer for channel power monitoring and an LED for clipping and temperature indication. The Classic AMP supports both balanced and unbalanced inputs, can be bridged for mono operation (200W into 8Ω), and is suitable for bi-amplification setups. Built in Switzerland, it is renowned for its precision, reliability, and musicality.
