Naim New Classic 300 Series - Redefining Your Very Own Legacy.

If there is one brand synonymous with crafting truly reference-grade audio equipment, it is undoubtedly Britain’s Naim Audio. For more than 50 years, Naim has been shaping the landscape of high-fidelity sound, designing systems that embody musical purity, engineering discipline, and an ever-evolving vision of what modern hi-end can be. Every few years, the brand revisits its own heritage, not to correct it, but to elevate it refining its lines with more sophisticated engineering and deeper musical insight.

The New Classic 300 Series stands precisely in that tradition: a three-component, modular ecosystem created for the demanding listener. Positioned above the Classic 200 Series line introduced in 2023, the 300 Series consists of the NSS 333 digital hub and streamer DAC, the NAC 332 high-precision analogue preamplifier, and the NAP 350 monoblock power amplifier.

The Architectural DNA of the 300 Series

The life of the modern audiophile is no longer defined by a powerful amplifier or a good DAC alone, but by a flexible, future-proof platform, one that remains relevant without demanding constant, costly upgrades. This is the core philosophy behind the New Classic 300 Series: a modular architecture built around the user’s needs, delivering top-tier performance at every stage, while allowing multiple upgrade paths without altering the heart of the system. With carefully executed mechanical design, isolated subsystems and digital precision of the latest generation, Naim once again redefines what true long-term high-end performance looks like.

NSS 333 – The Digital Heart

The NSS 333 operates as the central digital hub in a system built for true reference performance. Based on the NP800 platform, it employs symmetrical LVDS* transmission for ultra-low electrical noise and incorporates dual master clocks (44.1 / 48 kHz families) to achieve exceptionally low jitter**.

*LVDS (Low-Voltage Differential Signaling) uses differential digital transmission at very low voltage, ensuring minimal noise, strong resistance to interference, lower jitter, and extremely clean data transport—keeping the audio signal intact even across internal distances.

**Jitter refers to tiny, unwanted timing variations in a digital signal.

Signal Processing, DAC Performance & Streaming Capability

The incoming signal is processed through DSP up to 705.6 / 768 kHz before reaching the PCM1791A DAC, and then flows into a fully discrete Class A analogue stage. This combination of high-quality oversampling and refined analogue design delivers clarity, stability and micro-detail, especially in high-resolution recordings. The NSS 333 supports TIDAL, Qobuz, Spotify Connect, internet radio, AirPlay 2, Chromecast, UPnP, Roon Ready functionality and Bluetooth aptX. Whether the listener prefers casual streaming or serious hi-res playback, the system adapts effortlessly without requiring different platforms or devices.

Control Through the Focal & Naim App and the “Quiet Path” Philosophy

The Focal & Naim app provides a fast, ergonomic interface that centralises source management and multi-zone control. Roon Ready compatibility enhances workflow, metadata organisation and precise signal mapping. The LVDS signal path and low-jitter design ensure a remarkably clean digital environment, letting micro-details and tonal subtleties pass unaltered through the chain. The NSS 333 is, in many ways, a reference point for minimalist, high-performance digital systems.

NAC 332: A Preamplifier with Statement DNA

When the legendary Statement S1 sets the benchmark, the NAC 332 translates that philosophy into a fully discrete Class A circuit. Volume is controlled via reed relays and an optical encoder, ensuring perfect channel matching and a tactile smoothness rarely found in this price category. Discrete symmetrical Class A stages, hand-selected polystyrene capacitors and a bidirectional ZigBee RF remote give the NAC 332 a sense of engineering discipline wrapped in a welcoming, highly functional interface.

NAP 350: Monoblock Power with Absolute Control

The NAP 350 is the muscular core of the system, engineered to drive demanding loudspeakers without compromise. Delivering 175 W into 8Ω, 345 W into 4Ω and up to 1.7 kW peak, it responds instantly to musical transients with stability and effortless scale. Featuring NA009 transistors from the Statement Series, DR (Discrete Regulator) power technology and a high-current dual-channel output stage, the NAP 350 achieves impressive dynamics, exceptional noise control and a robust thermal design. With an S/N ratio of 114 dB and frequency response up to 100 kHz, its speed, clarity and fluidity become unmistakably Naim.

NPX 300: The Upgrade That Changes Everything

The NPX 300 powers either the NSS 333, the NAC 332, or both independently. By isolating power supplies, noise is reduced dramatically and transparency, depth and micro-detail increase. For demanding audiophiles, the NPX 300 is among the most transformative upgrades available in a Naim ecosystem, bringing precision and stability that are instantly audible.

Compatibility & Design Philosophy

True to Naim tradition, the New Classic 300 Series maintains compatibility with earlier Naim products via dedicated interconnects, something few brands continue to offer in an era of forced, rigid updates. The design remains strictly functional, built with high-grade materials, aluminium heatsinks, galvanic isolation and soft-start procedures that protect sensitive circuitry. This is engineering discipline with musical intent.



Conclusion

The Naim New Classic 300 Series radiates technological maturity and stands as a complete expression of Naim’s philosophy: the pursuit of perfect balance between analogue purity, digital innovation and musical soul. Launched shortly after the brand’s 50th anniversary, marked by the limited NAIT 50, the 300 Series captures Naim’s vision for the future while remaining firmly rooted in its British heritage.

Its understated industrial design avoids anything that could compromise performance, while carefully selected materials, thermal management and isolation techniques reflect a devotion to stability and sonic integrity. At the heart of this system lie the NSS 333, NAC 332 and NAP 350, three harmoniously engineered elements that connect sound directly with the listener’s consciousness. Paired with world-class loudspeakers such as Focal Sopra or Utopia, the New Classic 300 Series delivers an experience where British engineering meets French acoustic artistry, revealing the true essence of modern high-end audio.
