It is fashionable to omit tone controls nowadays: However, provided
that the tone controls are properly designed, they can be really
useful tools in making improvements to the overall sound. The
C355 tone controls only work at the frequency extremes leaving
the critical mid-band essentially unaltered. The tone control circuits
can be completely bypassed by using the tone defeat switch.
The C355 also incorporates NADs acclaimed switchable Soft
Clipping circuit, which significantly reduces the risk of damage to
loudspeakers due to prolonged high power operation.
Design: PowerDrive-„¢
The C355 also benefits from NADs proprietary PowerDrive
circuit topology, now well established and used throughout
the NAD product range. The PowerDrive topology allows the
C355 to deliver maximum performance under virtually any
circumstance, independent of the loudspeakers it is driving. The
circuitry automatically senses the impedance characteristics of
the loudspeaker and will then adjust its power supply settings
to best cope with that specific load. PowerDrive topology is a
practical approach for enabling an amplifier to easily deal with
musical dynamics and difficult speaker loads. Thus we have the
highly desirable characteristics of high dynamic power and low
impedance drive capability in one affordable package.
NAD also takes a stand against the meaningless brochure power
touted by many of our competitors by offering Full Disclosure
power specs. We specify minimum continuous power, across the entire audible range of frequencies, at rated distortion, for both
8 and 4 Ohms with all channels driven simultaneously. Perhaps
even more importantly, we also specify Dynamic Power at 8, 4,
and even 2 Ohms, which better describes the way the amplifier
will perform in the real world, with musical signals and reactive
loudspeaker loads.
Less Distortion = More Music
Noise and distortion mask the fine details of a musical recording
robbing musical texture and dimension and replacing them with
non-musical artifacts. NAD is has spent the last 35 years perfecting
our designs to have the lowest distortion and highest power in its
price class. This cannot be overstated! Our competitors often rate
distortion at only 80% of rated power, and even then cant match
our very conservative spec of 0.03% at any frequency within the
range of human hearing. At 80% power our distortion drops to
0.005% or less. Our noise spec is often 10dB (100 times!) less
than that of competing amplifiers. This is far from trivial.
However, even the most carefully reported specs cannot fully
describe the sonic performance of an amplifier. Only your own
ears can finally judge our achievement. We urge you to listen and
compare NAD to other products in its price range, and even higher.
We dont think youll find anything that comes close to offering the
C355s overall musical satisfaction, well-rounded performance,
and stellar value for money.
