immersing you in the musical or cinematic moment.
Unlike most surround sound receivers (NAD's own receivers are a
rare exception) that only rate power with 1 or 2 channels running,
or use very short term measurements, the T955 can deliver its
full rated power continuously for long periods of time. And dynamic
power, the power that more closely represents the true nature of
musical signals, is nothing short of sensational.
Sophisticated circuitry
The T955 is comprised if 5 individual 'Mono-block' amplifier
channels. Based on NAD's proven all discrete circuit topology
as used in the award winning C352 and C372 stereo amplifiers,
this design offers very low distortion combined with extremely
high current capability. Active current sources and common
base current followers in the power amp section combine to
improve supply rejection to unprecedented levels, well beyond the
audible frequency range. This has the effect of reducing dynamic
intermodulation distortion between music signal components in
different frequency ranges, and between these signals and supply
ripple and distortion components. In measurement terms static
and dynamic IM distortion are reduced by between 10dB to 20dB.
(to between -90dB and - 100dB.) compared to conventional
designs.

In audible terms this improves definition, purity and resolution,
hence imaging. And yes, imaging is very important in an amplifier
designed for surround sound listening.
sound component will surround you with sound, but the best
surround sound components have the effect of transforming your
listening room into the sound stage of the musical or cinematic
performance.
NAD's PowerDrive™ circuitry is a big part of this performance
story. By measuring each channel's dynamic impedance individually
and computing the optimum power supply voltage required to drive
the output stage for maximum power and efficiency. PowerDrive
permits high dynamic power and low impedance drive capability,
while maintaining ultra low (<0.03%) levels of distortion.
Each channel has individual over current, DC, infrasonic and
ultrasonic overload sensing and protection for complete reliability
under even the most severe operating conditions.
Custom designed heat sinks keep things cool under the most
severe operating conditions without the requirement of forced air
cooling and its potential noise. A massive Holmgren toroidal power
transformer insures excellent voltage regulation under the most
demanding conditions, and offers high efficiency and a low stray
magnetic field to help keep distortion at vanishingly low levels.
