To get the best out of your loudspeakers and music, combine the NSC 222 with its perfect partner: the NAP 250 power amplifier. First appearing in 1975, NAP 250 has become an iconic product. Today, it delivers more power than ever and offers ever more flexibility within a complete system. The cutting-edge engineering work involved in the NAP 250 results in unrivalled performance. It delivers 100 watts of A/B class power per channel, fully adjustable to set your music free in the most remarkable way.

The best of Naim
The cutting-edge design of the NAP 250 means it can be used even at high sound levels: its heat sink reacts to the increased volume, keeping the product “cool”. Other improvements include the addition of symmetrical XLR connections and a series of technologies derived from Naim's iconic Statement amplifier, including a eddy current separator available between the loudspeaker outputs. It also incorporates the Naim Audio DR (Discrete Regulator) technology found in the Statement, to benefit from the stable, fluid power supply we know to be essential.

Naim know-how
Under the guidance of Technical Director, Naim’s specialist engineers have developed simple but elegant circuits, combined with acclaimed and high-performing DR technology, guaranteeing the stable and fluid power supply so essential for superior performance. Naim teams opt for the highest-quality components including Statements NA009 power transistors and perform ultra-precise measurements for an uncompromising result.

The story of Naim and aluminium
The 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. While other manufacturers were bending thin sheets of steel, Naim used thick plates of aluminium.
