SA-7S1

Stereo Super Audio CD Player

Although most people think of the Marantz heritage as one based
on preamplifiers and power amplifiers, Marantz was the first
company in the world to announce a Compact Disc player! Since that
groundbreaking event, Marantz has led the way in offering advanced
digital playback with an unwavering focus on sound quality.

The

SA-7S1, unabashedly designed for the finest two-channel music
reproduction possible, continues that tradition.

Capable of playing CDs, CD-Rs, CD-RWs, and stereo Super Audio CDs,
the SA-7S1 combines several significant technical accomplishments
to advance your musical enjoyment.

As are other Reference products, the SA-7S1’s circuitry is housed in a
double-layer, copper shielded chassis for dimensional stability and
thorough isolation from external interferences.

The power supply includes a high-capacity toroidal transformer entirely
shielded by a silicon steel plate and a copper-plated case. This keeps
magnetic radiation from affecting internal circuitry.

The disc transport itself is a Marantz-designed example of exceptional
metal crafting. The mechanism sits in a case of extruded aluminum
while the disc drawer is cast to exacting tolerances. Servo and signal
processing circuits are situated on a four layer glass epoxy board
mounted close to the transport.

A Marantz-developed digital filter/noise shaper with user-selectable
characteristics (including digital phase inversion) operates on new pro-
prietary algorithms. Independent D/A converters process either PCM
information from a CD or DSD data streams from Super Audio CDs.
A high-accuracy master clock insures precise timing for extreme clarity.

A unique Digital Isolator completely separates ground connections
between digital and analog circuitry for optimal isolation. After this,
two D/A converters, each composed of four separate processors,
provide 24-bit resolution for both PCM and DSD signals.

Analog circuitry follows the Marantz maxim of proven quality enhanced
with the best contemporary technology. Fully balanced circuits benefit
from multiple Hyper Dynamic Amplifier Module (HDAM®) modules
in critical sections.

The output buffer amps are HDAM SA2,

chosen for their outstanding speed and timbral accuracy.

Aesthetically, the SA-7S1 evidences the typical care that has always
distinguished Marantz products.

The clean yet functional design

is another manifestation of our desire to meld sound quality
and superior appearance. The SA-7S1 is indeed a Reference.
And indeed a Marantz.

“If a composer could say what he had to say in words he would

not bother trying to say it in music.” -
