About the NP1
The Audio by Van Alstine NP1 is a current-production, two-channel Class AB stereo power amplifier employing the company’s Advanced Nested Architecture (ANA), a dual-control feedback/correction approach intended to reduce circuit nonlinearities. It is a straightforward analog power amplifier with one unbalanced line-level input; it does not include a preamplifier, DAC, phono stage, headphone output, streaming functions, or wireless connectivity. Its linear power supply uses a high-capacity toroidal transformer. The NP1 is intended for loudspeakers with nominal impedances of 4 ohms or higher and requires an actively buffered source or preamplifier with output impedance no greater than 1 kOhm; unbuffered passive preamplifiers are not recommended.
