The NAP350 is an industry-leading monobloc power amplifier from Naim Audio, which offers a multitude of loudspeaker options. Its dynamic power drives even with the most demanding loudspeakers. It can be used alone or combined with others as required by the system. Thanks to its silent cooling system, the NAP350 is easy to install in your chosen environment with no sound disruption.

The NAP 350 offers 175 watts of class A/B power into 8 ohms (rising to 345 watts into 4 ohms) in an elegant monobloc design. The NAP 350 is capable of +/-42 amps peak current into a 1 ohm load at 1.7 kW, meaning it delivers incredible dynamics, and can meet the needs of many of the most demanding loudspeakers available. It offers ultimate compatibility, thanks especially to its balanced XLR input which facilitates connections and can be combined with one or more amplifiers.

Priced at £11,999 per pair – individual examples are available on request.

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.

Newly developed output stage with double
driver and double power transistor – improved sound quality and more power.

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.

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.
