NAD C 328 Hybrid Digital DAC Amplifier

Description

NAD C 328 Hybrid Digital DAC Amplifier

For 45 years, NAD Electronics has introduced aspiring
audiophiles to the vast world of hi-fi. From our flagship Masters Series, to
our budget-friendly Classic Series, NAD has a component for everyone. Following
in the footsteps of some of NAD’s greatest units, the NAD C 328 delivers the
most fundamental of features, while firmly adhering to NAD’s unwavering
commitment to exquisite sound. The C 328 can wirelessly connect to any
smartphone, tablet, or Bluetooth®-enabled device within range, to give you a
seamless listening experience. Featuring a MM phono input, the C 328 breathes
new life into vinyl LPs, thanks in part to NAD’s innovative Hybrid Digital™ amp
technology. The C 328 also features a headphone amplifier, letting you connect
your favourite headphones and settle back into your own world of detailed
sound. Although more modest in comparison to other Classic Series amplifiers,
the C 328 will fit perfectly into your existing system and bring you the
musical nirvana you’ve been searching for.

Getting the Basics Right

When it comes to Classic Series amplifiers, no feature is
overlooked. Low noise circuits, precise volume control action, and accurate
channel balance are all key characteristics of the C 328. With the added bonus
of proper input and output impedance traits, plus high overload margins and
stability with difficult speaker loads, the C 328 is the best choice for
audiophiles who are just starting to build their dream systems. The C 328 also
includes a MM phono stage with precisely correct RIAA equalization, high
overload margins, extremely low noise, and an innovative circuit to suppress
infrasonic noise that is present on all LPs—all without affecting bass
response.

Versatility in Spades

The line inputs of the C 328 can accommodate all kinds of
analogue source components. It offers ideal input impedance attributes with
linear, ultra-low noise buffer amplifiers to prevent any sonic degradation
caused by improper loading of the source device. The C 328 also features a
separate headphone amplifier with low output impedance and very high output
voltage capability, enough in fact to drive even high impedance studio monitor
headphones. The low impedance line outputs can also connect to a subwoofer to
further extend the versatility of the C 328.

Ready for Streaming

With support for Bluetooth, you can instantly connect and
listen to the music service of your choice, or wirelessly stream music and
playlists stored directly on your smartphone, tablet or computer. Plus, with
its high performance digital circuitry, Bluetooth streaming has never sounded
as good as it does with the C 328.

Sophisticated Power

Since moving away from old-fashioned linear power supplies
and Class AB output stages, NAD has developed even better performing circuits
based on switch mode power supplies and Class D output stages. Once thought to
be inferior to traditional topologies, NAD’s advanced work in this area has led
to some of the best performing amplifiers on the market today. These new
designs are linear over a wide bandwidth and provide consistent performance
into all speaker loads, delivering a dramatic advancement.

The power supply of the C 328 is able to provide over 100
watts of audio output when needed. The C 328 can operate with any AC mains
voltage from 100V to 240V and provides pure DC power to all of its various
stages. This extremely efficient supply also provides near perfect regulation
of voltage across a wide range of conditions and provides a solid noise-free
foundation for the amplifying stages.

The C 328 uses a customised version of the proven Hypex UcD
output stage. This allows for massive power with nearly immeasurable distortion
and noise in the audible range. Every detail of this design has been carefully
crafted and perfectly executed to wring out the best performance possible. The
perfect starter amp for audiophiles and music lovers alike, the C 328 will
flawlessly deliver NAD’s signature flexibility and expansive power.
