Naim Know-How

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

Timeless Design

Naim products are designed to be both contemporary and timeless. Our creations forego any unnecessary decoration that does not contribute to performance targets or add to the sound quality. The design of the iconic NAP 250 power amplifier is functionally coherent, making it a pleasure to use. It also boasts extreme precision, combining a sleek design with innovative materials.

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.
