New Naim Classic 2023
The 300 Series line includes NSS 333, a high-resolution streaming solution, the NAC 332 preamplifier, the NAP 350 power amplifier, the NVC TT phono preamplifier and its dedicated power supply NPX TT.

NAC 332
NAC 332 is the “analogue centre” of your system, delivering optimal performance to your amplifier and loudspeakers. It is our most versatile preamplifier to date, allowing you to connect headphones as well as the NVC TT phono preamplifier for playing vinyl with incomparable quality.

Taking several elements from the Statement S1 preamplifier, a benchmark product at Naim, NAC 332 combines performance and versatility thanks to its multiple functions. It allows you to connect many sources, from an amplifier to headphones, as well as a turntable or CD player. Its optimised Naim circuits deliver enhanced musical performance from all your sources and limit internal noise for uncompromising sound quality.

Naim know-how
Under the leadership of Naim’s Technical Director, their engineers have developed specific electronic circuits to give the New Classic products superior performance. The best components have been chosen for NAC 332 and are mounted on printed circuit boards with metallic holes for increased quality. The architecture of the Statement volume knob has been used. Added to this are a high-performance transistor and balanced outputs that preserve sound quality over long distances and allow rack installation.

A timeless design
Naim products are designed to be both contemporary and timeless. Naim’s creations forgo any unnecessary adornments that would detract from the performance and sound quality delivered. The design of the NSS 332 is razor sharp, combining a sleek design, premium materials, and adjustable logo brightness.

Perfect integration in a complete system
NAC 332 links perfectly to the streamer NSS 333 and power amplifier NAP 350 from the New Classic range.

Easy to use
Simplicity is the key. Buttons on the front panel allow quick access to standby mode, mute, and the inputs. For remote control, use the features of the bi-directional ZigBee remote, even without direct visibility of the product. The inputs are configurable so the product can be customised and a “Standby” option, consuming 0.5 Watts, reduces its energy consumption.

The story of Naim and aluminium
Naim’s founder, Julian Vereker, immediately understood the many benefits of aluminium 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 maximises this highly technical and durable approach, with aluminium housings rivalled only by Statement, their flagship product. Naim chose a superior-quality aluminium, which optimally combines thermal and microphonic properties. The front panels are treated with solid 20mm-thick aluminium billets; heat sinks frame the side panels and 5mm plates cover the top and bottom surfaces of the products. The aluminium is brushed, sandblasted and anodised 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.
