The NAP 500 DR is a remarkable showcase of Naim Audio amplifier technology, which was perfected over a period of six years. Our highly skilled technicians in Salisbury spent days on the dedicated assembly, while specialist part suppliers collaborated to make this product possible. The NAP 500 features the NA009 transistors and Naim Audio DR technology. These, along with other minor enhancements, allow the NAP 500 to provide an even greater musical pace, rhythm, and timing.

Craft and Technology
The NAP 500 delivers 140W per channel and can output to 2 ohms without any performance impact. It has a two-box configuration with a separate 500 PS power supply for ultimate performance. Each channel includes ten stages of local regulation, and the 500 PS provides twelve raw D.C. supplies for the power amplifier.
The bridged configuration in the NAP 500 amplifier allows for high speed, less intrusive protection circuitry and reduced interaction between input and output signals. It also features the new output transistor, NA009, designed for maximizing bandwidth and reducing distortion. The circuit topology minimizes power supply dependency and thermally-induced noise.
