The Nagra Classic Power Amplifier is a distinguished solid-state stereo amplifier from the prestigious Swiss manufacturer, Nagra. Part of their “Classic Line,” it offers a compelling blend of Nagra’s iconic design heritage, featuring the signature modulometer, with advanced audio engineering.

This amplifier operates in pure Class A for much of its output, transitioning to Class A/B, delivering 100 W RMS per channel into 8 ohms (or 200 W RMS into 4 ohms). It can also be bridged for 200 W monoblock operation. Its meticulously designed output stage utilizes robust tandem MOSFET transistors, ensuring exceptional sonic purity and stability regardless of speaker load.

The Classic Amp incorporates a sophisticated power supply with an oversized transformer and power factor correction, providing immediate and dynamic response. With both balanced XLR and unbalanced RCA inputs, and housed in a precision-machined solid aluminum chassis, it embodies Swiss craftsmanship. Renowned for its natural, transparent, and dynamically expressive sound, the Nagra Classic Power Amplifier offers a genuinely musical and controlled listening experience, representing a pinnacle in high-end amplification.

- Generally, assembly of an equivalent output stage requires several pairs of transistors, which is difficult to achieve precisely. The simplicity of the CLASSIC AMP’s design is the key to its musicality.
- The input and driver stages also contribute equally to the overall performance and precision.
- The Nagra CLASSIC AMP is characterised by its stability, irrespective of the loads placed upon it.
- The power circuits drew particular care in the design stage.
- They are based upon an innovative concept: An overdimensioned transformer and a diode bridge are placed upstream of the PFC decoupling stage, used to actively correct the power factor.
- The filtering is achieved with a bank of capacitors, totalling 300 000 μF.
- This supply concept, which ensures efficient energy transfer, allows immediate reaction on even the most abrupt transients.
- The Nagra CLASSIC AMP is fitted with a traditional Nagra Modulometer on the front panel, showing the power of each output channel.
- An LED is also fitted to indicate saturations, excessive temperature.
- The amplifier is equipped with balanced and unbalanced inputs and in IN/OUT trigger function. It can be used in a bridged configuration, giving 1x 200 W into
- 8 Ω, and can also be used in a bi-amplification configuration if desired.
