NAP 250
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.
Key Features:
- Can be used with legacy products via the legacy range of cables.
- Separate DR PSUs for power amplifier, including the XLR input stage.
- Eight NA009 Naim custom designed power transistors as developed for Statement (4 for the PSUs and 4 for the output stages). Each mounted on ceramic insulators for ultra low capacitive coupling.
- New triple transistor constant current source (CCS) in delicate gain stage – uses a newly developed CCS for improved sound quality.
- Party-proof: new heatsink design responds to temperature fluctuation, keeping things cool.
- 20 minute auto power off for legacy systems, will wake on detecting music (auto off can be disabled).
- 0.5W standby power Using two internal power supplies; one is a high quality audiophile linear type, based on a large toroidal transformer. The other is a highly efficient SMPSU for 0.5W power consumption in standby during standby mode.
- Soft-start power up sequence, preventing the large toroidal transformers from tripping mains circuit breakers due to the large influx of voltage required.
- 3.5mm optical inter-product communications for synchronised system control, preventing ground loops. This facility offers LED brightness and power control.
- Eddy current divide situated between speaker output terminals for improved sound quality.
- Custom audiophile components such as polystyrene capacitors in filter circuits for low dielectric absorption.
- Through-hole components reducing microphonies picked up via the circuit board fluctuations.
Elegant Engineering
Naim’s highly skilled engineers have created circuits that are both simple and elegant, perfectly complemented by our renowned DR technology. This combination guarantees a stable and smooth power supply, leading to exceptional performance. Our team uses only the best-quality components, including Statement’s NA009 power transistors, and employs ultra-precise measurements to guarantee an uncompromising result.
At Naim, we believe that our products should be both contemporary and timeless. We always avoid adding unnecessary decoration that does not contribute to performance or sound quality. Our iconic NAP 250 power amplifier is designed with both functionality and precision in mind, making it easy and enjoyable to use. Its sleek design and innovative materials make it a true masterpiece of audio engineering.
Aluminium
Naim’s founder, Julian Vereker, understood the benefits of using thick plates of aluminium to wrap electronic components. This decision helped to minimise the negative effects of magnetic fields, unstable temperatures, and vibrations on Naim’s audio products.
Perfect Pairing
For the optimal performance of your loudspeakers and music, the ideal combination is the NAP 250 and NSC 222 preamplifier and streamer. The NAP 250 can be easily connected to any of the New Classic products, as well as the previous Classic lines via new specific cabling. With 100 watts of A/B class power per channel, the NAP 250 can be fully adjusted to bring out the best in your music and deliver a remarkable audio experience.
The cutting-edge design of the NAP 250 keeps it cool even at high sound levels with its responsive heat sink. It also has symmetrical XLR connections, eddy current separator, and Naim Audio DR technology for stable, fluid power supply and exceptional performance.
