Naim Audio’s iconic amplifier: back and better than ever.
In production since 1975, the Naim NAP 250 power amplifier has gained iconic status.
This new sixth-generation model delivers more power than ever before; state of the art engineering provides unrivalled performance, greater system-matching and flexibility.
Designed & built in the UK, it is ready to drive the speakers of your choice — taking your music to new heights.
Naim NAP 250
To get the best out of your loudspeakers and music, combine the NSC 222 with its perfect partner, the NAP 250 power amplifier.
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 they know to be essential.
Naim know-how
Under the guidance of their Technical Director, Naim’s specialist engineers have developed simple but elegant circuits, combined with their acclaimed and high-performing DR technology, guaranteeing the stable and fluid power supply so essential for superior performance.
Their teams opt for the highest-quality components and perform ultra-precise measurements for an uncompromising result.
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.
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.
