Precision Engineering for Dynamic Musical Performance

The NAP 350 represents a significant achievement in Naim's New Classic amplifier range, delivering high power with the precision and speed that complex musical passages demand. Naim's engineering team has developed specific electronic circuits that set these monoblock power amplifiers apart from conventional designs. At the heart of each NAP 350 sits a new high-current output stage employing matched pairs of the NA009 custom power transistors—the same components refined for Naim's flagship Statement amplifier series.

Combined with Naim's acclaimed DR (Discrete Regulator) technology, the NAP 350 guarantees stable power supply performance with exceptionally low noise floors. This regulated power supply architecture ensures that dynamic musical peaks receive the instantaneous current delivery they require, whilst maintaining the black silence essential for revealing low-level detail. The result is a power amplifier that captures the true dynamics of music, from the gentlest pianissimo to full orchestral fortissimo, without compression or constraint.

Superior Sound Quality Through Thoughtful Design

Running as a pure class-AB linear amplifier from fully regulated DR power supplies, each NAP 350 produces 175 watts into 8 ohms and 345 watts into 4 ohms. More significantly, the amplifier can deliver peak power of up to 1.7 kilowatts—essential capability for driving the impedance dips inherent in complex loudspeaker crossover networks. This substantial power reserve ensures that even the most demanding floor-standing speakers receive the control and authority they need across the entire frequency spectrum.

The NAP 350's balanced XLR input facilitates seamless integration within professional and domestic hi-fi systems alike, offering superior common-mode noise rejection compared to single-ended connections. For those with existing Naim systems, a legacy adaptor lead enables single-ended connectivity whilst maintaining the amplifier's exceptional performance standards.

Timeless British Design Philosophy

The NAP 350 exemplifies Naim's clear-cut design principles, where every element serves a functional purpose. Premium materials include highly thermally conductive aluminium alloy heatsinks that dissipate heat efficiently whilst contributing to the amplifier's elegant visual presence. Naim's founder, Julian Vereker, immediately understood aluminium's benefits for housing sensitive audio components—protection from magnetic field interference, temperature stability, and resistance to unwanted vibrations that can compromise sonic purity.

At just 9.15cm in height, the NAP 350 maintains Naim's signature low-profile aesthetic whilst accommodating the substantial power supply and output stage components within. The aluminium casework not only provides electromagnetic shielding but also contributes to mechanical damping, ensuring that the delicate audio circuitry operates in an optimally stable environment. This is engineering where form follows function, with no unnecessary embellishment to detract from performance and sound quality.

Perfect System Integration

The NAP 350 combines beautifully with the NSS 333 music streamer and NAC 332 preamplifier, creating a complete New Classic system that leverages Naim's system automation capabilities. The included optical system automation cable enables seamless power-on sequencing and volume control integration, whilst the supplied balanced XLR interconnects ensure optimal signal transfer between components.

Each amplifier pair arrives with Power-Line Lite mains cables, balanced audio interconnects, and system automation cabling—everything required for immediate installation. The NAP 350's modest 24W consumption during normal operation reflects efficient class-AB design, whilst deep sleep standby mode draws less than 0.5 watts, demonstrating environmental consideration alongside sonic excellence.

Heritage & Craftsmanship

For over five decades, Naim Audio has refined the art of amplifier design from its Salisbury headquarters, earning worldwide recognition for products that prioritise musical engagement above all else. The NAP 350 continues this British engineering tradition, incorporating technologies developed for Statement—Naim's £150,000 reference amplifier system—and making them accessible within the New Classic range. Each amplifier undergoes rigorous testing and quality control to ensure it meets Naim's exacting standards for long-term reliability and consistent performance.

The use of custom NA009 power transistors—components specified and refined specifically for Naim amplifiers—demonstrates the company's commitment to controlling every aspect of the signal path. These aren't off-the-shelf semiconductors but purpose-designed devices that deliver the speed, linearity, and current delivery capability that Naim's engineering philosophy demands.
