Purity for the purists
Marantz follows up on the tradition of high quality stereo SA-CD
players. Based on the well received SA8400 Super Audio CD
Player the SA7001 brings superb audio quality to all music
lovers. This is the answers to concerns of audiophiles regarding
functional integration of CD playback at the costs of audio
quality. This player utilized all the benefits of the SA-CD format
in stereo, of course allowing also standard CDs to be played
back at high level quality. The SA7001 brings you all the depth,
dynamics, and sonic excellence you’ve come to expect from
Marantz’ finest components. And at a cost that puts the best
within the reach of almost everyone.

Super Audio playback
Enjoy the fabulous world of high resolution audio! Finally you
can have an incredible live-experience in your home as it was in
reality. Not only is the total ambiance reproduced, but also the
natural 'sound' of the instruments is being preserved. SA-CD is
based upon the DSD conversion principle that links excellent
specifications like a frequency range of 100 kHz and a dynamic
range of 120 dB, to superb sound quality.

The 'Super DAC'
The outstanding D/A converter, boasting a successful heritage
in high-end machines including the SA-15S1 and SA8400,
produces clear sound for Super Audio CDs and regular CDs
alike. The CS4397, 'Super DAC', from Cirrus Logic is developed
to provide high quality audio output for new standards such as
SA-CD. It incorporates Cirrus Logic's mixed-signal technologies,
including Switched Capacitor techniques, Multi-bit Delta Sigma
Modulator architecture, and Dynamic Element Matching. All this
results in an unsurpassed dynamic range and detailed
resolution, which are key to a striking SA-CD performance.

Current Feedback HDAMs
Audio devices are usually equipped with Op-Amps (operational
amplifiers) for which Integrated Circuit (IC) are commonly
used. Unfortunately these IC's do not match the very high
requirements of Marantz. Marantz developed it's own discrete
circuit boards to replace the IC's. These HDAM's consists of
discrete surface mount components with short mirror image L/R
signal paths. Those devices are doing exactly the same thing as
the Op-Amps, but outperform the regular IC Op-amps
dramatically in terms of the Slew Rate, resulting in a much more
dynamic, accurate and detailed sound, as well as on the signal
to noise ratio. The Marantz HDAMs offering very low noise
operation. There are no IC OP-amps used at all in the SA7001's
analogue signal path.

Full system control

The SA7001’s analogue audio circuitry is a full discrete design
including newly developed Current Feedback HDAM modules
that operates as a buffer amplifier and as a Low Pass Filter. Both
channels are completely identical in terms of components and
circuit layout. This is extremely important to be able to enjoy a
breathtaking sound stage of stereo SA-CD material.

Customized
Every Marantz product is designed with a fine ear and eye for
details. The designers have to know the characteristics of every
component. On paper the component might look excellent but
the result may fall short of the combined design expectations.
Therefore Marantz collects vast amounts of information upon
specifics component performance capabilities. Marantz selects
the appropriate components for the specific design application.
The sonic result is then critically acclaimed by international
reviewers. In other cases it's simply not possible to use standard
components that meet the high Marantz standards. These
components will then be specially made for Marantz only in co­operation with the Marantz engineers.

A touch of Marantz
The strength of each Marantz design can be found in the
attention to detail and cohesiveness of the different elements.
The SA7001 is a clear example of benchmark engineering and
craftsmanship and features a number of Marantz sound
enhancements. The SA7001 SA-CD player is built on a solid
metal chassis. Extensive bracing and shock-absorbing feet result
in minimized internal vibration and mechanically induced jitter.
All of the digital, analogue and control circuits are separated
and shielded in their own enclosures to prevent cross-talk and
other unwanted interference. Independent power supplies for
each dedicated system block secure maximum separation,
clarity and dynamics. Symmetrical lay out hand-selected
Customized Components, gold-plated terminals and the renown
Marantz Current Feedback HDAMs all work in harmony. This
design configuration is capable of a 'live experience'
reproduction of the most complex music pieces composed.

Personal enjoyment
For the headphone listeners we have paid extra attention to the
headphone circuitry to ensure that the pure emotion of SA-CD is
passed on. A dedicated amplifier is developed with a fast
current-buffer amp, constructed of discrete components only,
including a high grade potentiometer for the volume control.
