During the years of research that went into the NAP 500, many technical developments came about that could be successfully applied to the NAP 250. Many of these developments, along with the elegant new styling have been incorporated, resulting in a new Classic line-up.
Like the flagship NAP 500, and the NAP 300, the NAP 250 uses a new circuit design with improved earthing arrangements, built on a very high quality, anti-resonance main audio circuit board. The NAP 250 uses the same 007 transistors that were custom-designed for the NAP 500. These outstanding components each provide up to 80 amps and 350 Watts, negating the need to use parallel pairs of transistors (which always have a negative effect on sound).
The 250 also includes the high power Naim Audio DR (Discrete Regulator) technology used in Statement to provide the smooth, stable power supply we know is critical for the audio electronics to make music come to life.
Additional 007 transistors are used in the fully regulated power supply, ensuring the very best performance. Anti-vibration, resonance-controlling feet serve to protect the sensitive internal components from resonance and microphonic vibration. A new top-quality transformer is used providing the ability to deliver more than 15 Amps and swing a massive 400VA on transients. The NAP 250 is stable into any load and able to drive a 2-Ohm load for long periods of time.
