Naim NAP 500 DR

Naim NAP 500 DR eindversterker

The devil is in the detail.
As the debut product in our reference 500 Series range, the NAP 500 is a
monumental expression of Naim amplifier technology. Its design was honed over
six years of collaborative work with suppliers of specialist parts and each
product takes days of dedicated assembly by our most skilled technicians in
Salisbury. It’s this eye for detail, alongside its remarkable power, that allows
the NAP 500 to bring your music into breath-taking focus.

New for 2015 – Statement technology
Our flagship Statement amplification system was ten years in the making. The
research and development project drew on all of our knowledge and expertise,
yielding several breakthroughs in technology. Now for 2015 we’ve introduced two
new technologies from the Statement project to our core range of power
amplifiers.

The NAP 500 now features the new NA009 transistors first introduced in
Statement. In development for over a year, this key component was created in
partnership with a specialist semi-conductor manufacturer to achieve the best
possible sound quality. The 500 also includes the high power Naim 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.

These two new technologies, combined with other small improvements to layout and
componentry, mean the NAP 500 DR can produce even more of the fundamental
musical pace, rhythm and timing that made the originals so popular with music
lovers.

Technology & Craft
The NAP 500 delivers 140W per channel into 8 ohms and is capable of prolonged
output into 2 ohms with no discernible impact to performance. Its two box
configuration is classic Naim, with the power supply completely removed to the
separate 500 PS power supply for ultimate performance. Each channel of the NAP
500 includes ten stages of local regulation. To reduce interference from the
mains supply further, the transformer and first stages of the power supply are
in a separate enclosure, the 500 PS, which provides twelve raw D.C. supplies for
the power amplifier.

A bridged configuration allow for maximised open and closed loop speed, less
intrusive protection circuitry and reduced interaction between input and output
signals as the very high drive currents to the loudspeaker do not flow through
the system earth. The NAP 500 also features an advanced output transistor, the
007, specifically designed for the purpose through months of collaborative work
with a specialist supplier. The circuit topology has been developed to maximise
bandwidth and reduce distortion and power supply dependency. Also, special
attention has been paid to reducing thermally-induced noise, an especially
important consideration in power amplifiers.
