Like the flagship NAP 500, the NAP 200 uses a new circuit design with improved earthing arrangements built on a very high quality, anti-resonance main audio circuit board. Anti-vibration, resonance-controlling feet serve to protect the sensitive internal components from microphonic vibration and unwanted external interference.
A new, top-quality 430VA toroidal transformer provides more than 300VA of transient power. Separate windings provide dedicated left and right channel rectified power supplies with two smoothing capacitors per channel. The NAP 200 also has a separate winding providing a preamplifier power supply. This enables it to be used in a two-box amplifier configuration with a Naim Audio preamplifier such as the NAC 202. The Naim Audio NAP 200 is stable into any load and can drive a 2-ohm load for long periods of time.
