Naim NAP 500 DR Power Amplifier
The Naim NAP 500 DR is a flagship power amplifier built to deliver outstanding musical performance with exceptional control and clarity. Carefully engineered and assembled by expert technicians in Salisbury, it reflects years of refinement and attention to detail. With its separate power supply design, it helps reduce interference and supports a cleaner, more dynamic sound. Powerful yet composed, the NAP 500 DR brings greater rhythm, depth and realism to music, making it an ideal choice for high-end hi-fi systems.
Features
- 140W per channel output into 8 ohms; capable of prolonged output into 2 ohms with no discernible impact on performance.
- Bridged power amplifier configuration for maximised open and closed-loop speed, with ten stages of local regulation per channel.
- Two-box configuration with 500 PS power supply for optimum rejection of electromagnetic interference.
- 1,100VA toroidal transformer provides 12 raw DC supplies for the power amp.
- 25kg brushed, black-anodised chassis with distinctive heatsink plus variable speed intelligent fan system for discreet extra cooling if required.
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.
