Naim NAC 332 Preamplifier

The Digitally Controlled, Pure Analogue Heart of the New Classic 300 Series

Inspiration drawn from 50 years of British audio heritage meets ultra-modern analogue circuit innovation. The Naim NAC 332 is Naim’s reference New Classic analogue preamplifier, engineered as the versatile command center for high-end stereo systems where uncompromised signal purity, dynamic pace, and complete source control are required.

Housed in a precision-crafted, solid aluminum enclosure designed to suppress external vibrations and electromagnetic interference, the NAC 332 features Naim's signature brushed finish, a backlit dimmable logo, and an engineered precision-raced bearing volume dial.

Engineering Marvel: Statement-Derived Volume Control, Fully Discrete Circuitry

Don't let its refined exterior deceive you. Under the hood, the NAC 332 features fully discrete transistor gain stages and an audiophile volume architecture directly derived from Naim's flagship $300,000 Statement system. Utilizing reed relays to switch between ultra-precise fixed resistors, it provides perfect channel balance, zero potentiometer noise, and granular input sensitivity trimming across all sources.

Key Performance & Technological Innovations

8 Fully Configurable Analogue Inputs: Accommodates up to 8 physical inputs across 2 x Balanced XLR pairs, 3 x Unbalanced RCA pairs, 2 x 5-pin DINs, and 1 x powered 8-pin DIN. Front-panel buttons can be mapped to any socket.

Statement Fixed-Resistor Volume Architecture: Reed-relay switching across precision through-hole fixed resistors guarantees pristine channel tracking, ruler-flat linearity, and ultra-low noise.

Class-A Headphone Amplifier: Features a dedicated front-panel 6.35mm (1/4") headphone output driven by a state-of-the-art 1.5W Class-A amplifier stage capable of driving demanding audiophile headphones.

Powered DIN Stage for NVC TT Phono: Dedicated 8-pin DIN input provides clean $\pm18\text{V}$ power directly to the Naim NVC TT phono preamplifier.

Bi-Directional Zigbee Remote & System Automation: RF remote control allows non-line-of-sight operation, with optical inter-product links to seamlessly synchronize power and logo dimming with New Classic power amplifiers (like the NAP 350) and streamers (NSS 333).

Upgrade Ready (NPX 300 Compatible): Can be powered directly from the mains or upgraded with the external Naim NPX 300 power supply to completely bypass the internal power transformer for an even lower noise floor.

Audition the Naim Experience at Brisbane HiFi

Sound this visceral, detailed, and musically engaging needs to be heard and felt in person. From the razor-sharp timing and dynamic punch characteristic of Naim engineering to the dead-silent background required for delicate acoustic recordings, the NAC 332 sets a benchmark for modern analogue preamplification.

At Brisbane HiFi, our dedicated audition spaces offer the ideal setting to experience the Naim NAC 332. Whether you are building an uncompromised New Classic 300 Series system or integrating it with your existing reference power amplifiers, our expert audio team is here to guide your audition.
