I am shrinking my AV system and so am selling my Marantz
Pre/Pro (separate ad) and this well-respected power amplifier.  It is a current Marantz model, and I am
the original owner.  I purchased it
from a Marantz-authorized dealer.  Features
balanced and unbalanced connectors, tons of quality power,  and the subtle blue lighting and
sculpted style that Marantz is known for. 
The amp is in excellent operational and cosmetic condition.  Includes owner’s manual and power cord.  I do not have the original box, but it
will shipped well padded in a heavy box similar to that the factor uses.  Please note the photos also include a picture of the companion pre/pro I also listed for sale.  This ad does not include the pre/pro; it is for the power amp only.

Power For Your System

The MM7055 power amplifier produces 140
watts of high current output from each of its five channels.  This is
“real world” power, too, measured across the full audio bandwidth (20 Hz – 20
kHz) at 8 ohms with 0.08% Total Harmonic Distortion.  Among other
attributes, this means the MM7055 is capable of long-term power delivery into
low impedance speakers.

Many Faces of Excellence

In practical terms, the MM7055 is ideal
for a “5.1” home theater system, whether based on a moderately powered receiver
or a surround sound processor.  You can use it to power speakers in
different areas of your home; stereo reproduction in two rooms plus a mono
channel for secondary areas such as a den or kitchen.  For more complex
home theater systems, the MM7055 pairs with one or several MM7025s to help
create a totally immersive “7.1” or “9.1” audio experience.

The MM7055

A massive power supply includes a
multiple-secondary EI-core transformer and over 65,000 µF of custom-designed
energy storage capacity.  Critical circuit components from many
world-class suppliers were chosen only after extensive listening tests. 
Among these, the LAPT Hyper Power output devices were first used in Reference
Series components.  Current feedback topology insures astounding accuracy
and control under high-drive conditions.

Temperature-Controlled Environment

\Physically, the MM7055’s output stages
mount on an extruded aluminum “thermal tunnel” for efficient heat
dissipation.  With temperature-sensing forced air cooling, this
configuration assures cool operating temperatures for long-term reliability,
even when making full use of the amplifier’s substantial output capabilities.


Balanced inputs and single-ended RCA
inputs are both supported, and you can choose either type of input for each
channel, individually, for easy and flexible connectivity.  Audiophile
grade, gold-plated four-way binding post speaker terminals insure tight
connections to your choice of speaker wire.


The MM7055 includes input and output
jacks for DC “trigger” pulses as well as RC-5 jacks for total remote control
convenience, even with legacy Marantz products.

The chassis itself is heavy gauge steel
for maximum isolation from external vibration as well as electromagnetic and
radio frequency interference.  And chassis depth is less than 14½” so the
MM7055 will fit quite nicely on a shelf, in a cabinet, or in a conventional
system rack with the optional rack mount kit RMK8003MM.

Power.  Functionality. 
Dependability.  And classic looks.  The MM7055 is, simply speaking, a
