As the debut product in our 500 Series reference range, the NAP 500 power amp is a monumental expression of Naim audio amplifier technology. Its design was perfected over six years of collaborative work with specialist parts suppliers, and each product takes days of dedicated assembly by our most highly trained technicians in Salisbury. It's this eye for detail, coupled with its extraordinary power, that allows the NAP 500 to bring your music into stunning focus.
New statement technology
Our flagship Statement power amp system was ten years in the making. The research and development project drew on all of our knowledge and experience, resulting in several advances in technology. We have recently introduced two new technologies from the Statement project to our core range of power amps.
The NAP-500 power amp now features the new NA009 transistors first introduced in the Statement power amp. In development for over a year, this key component was created in collaboration with a specialist semiconductor manufacturer to achieve the best possible sound quality. The NAP 500 also features the high power Naim Audio DR (Discrete Regulator) technology used in Statement to provide the stable and consistent power supply we know is essential for audio electronics to bring music to life.
These two new technologies, combined with other small improvements in design and components, mean that the NAP 500 DR can produce even more of the essential musical spacing, rhythm and timing that made the originals so popular with music lovers. .

NAP 500 power amplifier
technology and crafts
The NAP 500 offers 140W per channel into 8 ohms and is capable of long output into 2 ohms with no noticeable performance impact. Its two-box setup is classic Naim Audio, with the completely separate 500 PS power supply for maximum performance. Each channel of the NAP 500 includes ten stages of local regulation. To further reduce power supply interference, the transformer and first power supply stages are housed in a separate enclosure, the NAP 500 PS power supply, which provides twelve raw DC supplies for the stage. of power.
A bridged configuration allows for maximum open and closed loop speed, less intrusive protection circuitry, and reduced interaction between input and output signals, since very high drive currents to the speaker do not flow through the system ground. The NAP 500 also features the new output transistor, the NA009, designed specifically for this purpose through months of collaborative work with a specialized supplier. The circuit topology has been developed to maximize bandwidth and reduce distortion and dependency on the power supply. In addition, special attention has been paid to reducing thermally induced noise, an especially important consideration in power amplifiers..PZA MORE SPECS
