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 Naim know to be essential.

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