The NP1 Power Amplifier is the first stereo power amplifier to use Audio by Van Alstine's class-defining Advanced Nested Architecture (ANA).

The NP1 Power Amplifier oozes with the transparency, dynamic range, linearity, and pure music for which Audio by Van Alstine is known. Listen to all of your recordings again and you will hear acoustic space and musical nuance in a much more real and involving way. The cost is much less and the performance much better then you have any right to expect.

Amplifier Circuits

The NP1 Power Amplifier uses our Advanced Nested Architecture (ANA) technology to deliver stunning linearity and sound quality previously unimaginable at its price. It generates up to 55 watts per channel into 8Ω and is suitable for nominal 4Ω loads and up.

ANA is a major advancement in audio power amplifiers that brings you ever closer to the original source. Unlike more conventional amplifiers, ANA employs two independent control mechanisms to manage circuit nonlinearities. The first mechanism provides the kind of correction found in typical class AB audio amplifiers. To this, ANA adds a second global correction circuit that reduces nonlinearities to the vanishing point. We are confident that you will find the results exhilarating.

Power Supply Circuits

The NP1 Power Amplifier has an oversized, high-capacity linear power supply to fully support the incredible dynamic range, bass extension, and transient detail the audio circuits are capable of. All of the power supply parts are selected for long life, reliability and operate well within their technical specification ratings.

Additional Information

The NP1 Power Amplifier operates with standard 120V power. It has an IEC power socket, and we include a 120V IEC power cord.
