PREMIUM INTEGRATED STEREO AMPLIFIER
PREMIUM SERIES
The fully discrete confi guration current feedback circuit of this integrated amplifi er captures such details that
you can even hear the performers’ breath.
Newly Developed Custom Capacitor
A newly developed high sound quality capacitor is
used to support the high instantaneous current supply
capability. The same 3-set winding construction
used in high-end models is employed and wide
tabs are used to connect the electrode foil and the
terminals. Further, an element fixing agent is used
to gently and accurately secure the 3-set winding
construction electrode foil to provide rich sound. In
addition to using high sound quality parts, the ground
line was changed and other modifi cations were made
throughout by incorporating Marantz’s unique high
sound quality know-how.
Linear Control Volume
An inverting NFB circuit is used to successfully
eliminate the inverting amplifier that was necessary
to return the signal phase to the positive phase and
thereby achieve playback sound of higher purity. The
sound volume can be very accurately and smoothly
adjusted from 0 dB to 100 dB in 0.5 dB steps.
Further, there is very little cross talk and interlocking
error between channels, which contributes to greatly
improving reproduction of the sound fi eld space.
V/I Servo Current Feedback Power Amplifi er
Employs a V/I servo current feedback circuit that
boasts the same high stability as the power amplifi ers
in high-end models. A transistor is combined with
the HDAM-SA2 to serve as the input circuit and DC
servo circuit to build an onboard HDAM-SA3 circuit. A
powerful magnetic circuit and low loss network circuit
are provided to greatly improve the instantaneous
current supply capability to provide suffi cient drive at
high speed for the latest speakers, which require a
large drive force from the amplifi er.

Detachable Power Cord
The analog audio output circuit is equipped with
the same HDAM and HDAM-SA2 Marantz original
high-speed amp modules used in high-end models.
The fully discrete confi guration that does not use an
op-amp provides thorough low distortion, low noise,
and high-speed performance. You will enjoy the rich
musical performance that exceeds what is customary
for this class of product.
