Email Or Call To Order

In production since 1975, the 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 unrivaled performance, greater system-matching and flexibility. Designed in the UK, it is ready to drive the speakers of your choice — taking your music to new heights.

• 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.
