NAP 250

The iconic Naim amplifier 

First appearing in 1975, the NAP 250 power amplifier has become an iconic product. Its aesthetic and technical evolution has ensured its sustained first-rate performance over the years, creating unforgettable musical experiences. 

The new sixth generation model delivers more power than ever. Its ultra-modern technology provides unrivalled performance and system flexibility. Designed in Salisbury in the United Kingdom, it can be paired with the loudspeakers of your choice to deliver outstanding listening sessions.

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.

Le savoir-faire Naim
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.

A 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.

Perfect integration in a complete system

The NAP 250 can be connected to any of the New Classic products, but also to the previous Classic lines using a new range of specific cabling. Above all, it is the perfect partner for the NSC 222 preamplifier and streamer.

The story of Naim and aluminium
The story of Naim and aluminium

Our 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.

[+]

The Naim Classic range maximises this highly technical and durable approach, with aluminium housings rivalled only by Statement, our 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.
