Naim Audio NAP 350 New Classic Monoblock Power Amplifier

Our highly dynamic monoblock power amplifier

A benchmark amplifier; a pair of NAP 350s offer precise musical performance. Designed to effortlessly drive large and demanding loudspeakers, capturing the true dynamics of music.

NAP 350
The NAP 350 is a pure class-AB linear amplifier, running from fully regulated DR power supplies; producing 175W into 8 ohms and 345W into 4 ohms. It can deliver peak power of up to 1.7kW to drive impedance dips of complex speaker crossover networks. The input is via a balanced XLR socket, facilitating industry-wide compatibility.

Naim know-how
Under the guidance of our Technical Director, our engineers have developed innovative electronic circuits to give the New Classic products excellent audio performance. The NAP 350 has a new high-current output stage that uses matched pairs of Statement NA009 custom power transistors. Combined with our acclaimed DR technology, which guarantees a stable and low-noise power supply, the NAP 350 delivers high power with precision and speed.

Perfect integration in a complete system
NAP 350 combines perfectly with the NSS 333 streamer and the NAC 332 preamplifier.

A timeless design
Naim products are designed to be both contemporary and timeless. Our creations forgo any unnecessary embellishment that would detract from the performance and sound quality.
The NAP 350 combines a sleek design and premium materials such as highly thermally conductive aluminum alloy heatsinks.

The story of Naim and aluminum
Our founder, Julian Vereker, immediately understood the many benefits of aluminum as a material for wrapping Naim electronic components. He knew that delicate audio components are very sensitive to the effects of magnetic fields, unstable temperatures, unwanted vibrations, etc.

The Naim Classic range maximizes this highly technical and durable approach, with aluminum housings rivalled only by Statement, our flagship product. Naim chose a superior-quality aluminum, which optimally combines thermal and microphonic properties. The front panels are treated with solid 20mm-thick aluminum billets; heat sinks frame the side panels and 5mm plates cover the top and bottom surfaces of the products. The aluminum is brushed, sandblasted and anodized to guarantee unalterable beauty throughout the product's life. The New Classic range can be immediately distinguished with one look and one touch, before the first note of music even plays.
