Description:
The Marantz SA8003 brings advanced engineering to all manner of discs –
SA-CDs, CDs, even MP3- and WMA-encoded CD-Rs and –RWs. And its advanced
digital processing and best-in-class analog circuitry bring even your flash-card
playlists to life thanks to a front-panel USB input.
But Marantz design doesn't extend to just the obvious. As an example,
we'll ask a question: Almost no one thinks twice about the disc tray,
right? Well, Marantz engineers do. And when you realize that the tray is the
most important mechanical link between your favorite discs and the rest of the
disc player, you realize just how important it is.
That's why Marantz helped develop a material called Zylon for the SA8003's
tray. Zylon is a composition of rigid-rod chain molecules of poly(p-phenyene-2,6-benzobisoxazole)
or PBO for short. (Now you know why we call it Zylon!) This new tray material
has high tensile strength and a high modulus of elasticity. Because it isolates
the disc so well from the micro-vibrations inherent in any drive mechanism,
it allows the digital circuitry to process a more accurate data stream. This,
in turn, translate directly into a more coherent and pleasing aural experience.
While you're taking a virtual tour of the SA8003's interior, look
at the large toroidal transformer. In addition to the exterior casing that damps
stray flux fields even further, you'll notice a large brass mounting screw
that helps hold the transformer firmly in place. Why brass? Simply because it's
totally non-conductive dut to the non-magnetic material, it plays a role in
reducing extraneous noise. True, it might be a small improvement but it's
an example of the lengths to which Marantz engineers go to optimize every aspect
of a component's performance.
We'd also like to point out the separate power supply and audio circuit
boards that flank the transformer for even further noise suppression capability.
We've used the SA8003's high-performance Cirrus Logic digital-to-analog
converter in other – and far more expensive – disc players in the
past. This circuit brings several advantages. In technical terms, its architecture
combines a proprietary multi-bit/Delta-Sigma demodulator with noise shaping
technology. It eliminates the need for dynamic component matching within the
D/A converter itself as well as removes potential destructive artifacts from
the resulting signal. For SA-CD playback, the Cirrus IC accepts the SA-CD's
2.8224 MHz sampling rate directly without the need for decimation. And an integral
50 kHz low-pass filter protects downstream components from potential oscillation.
You'll also notice a number of critically selected parts at important
spots in the analog output circuitry. They've been chosen because they
meet the criteria established not only in the lab but also in the listening
room. And you'll see Marantz's proprietary HDAM SA2 circuits there,
too. Used primarily as output buffers, these HDAM circuits benefit from a discrete
component complement rather than earlier ICs.
Under all this advanced circuitry, you might not notice the double-layer chassis
bottom plate. But it provides long-term alignment for all the SA8003's
separate assemblies as well as helps damp external vibration.
If you look carefully, you'll certainly see the large copper plate behind
the machined, chassis-mounted gold-plated analog outputs. The plate minimizes
any ground potential between the outputs and results in quieter playback. The
outputs themselves are spaced to allow your choice of any interconnect. Mounting
them directly to the chassis means you won't pull them off when changing
cables. Small points? Well, not really. When you add up all the similar touches
within the SA8003, you'll understand their surprisingly-large cumulative
effect. And it results from an almost maniacal determination to make the SA8003
as good as it can possibly be.
The shielded digital output provides yet another example of this approach. Rather
than allowing spurious radiation, as is the case with most digital outputs,
the copper case effectively traps digital pulses and prevents them from interfering
with adjacent circuits.
The headphone output, usually far down on the priority list for lesser players,
includes a high-speed current buffer circuit for minimal interference, maximum
articulation, stability, and fatigue-free listening.
Complete with a soft-touch Power/Standby switch and full-function remote, the
SA8003 brings top-shelf disc playback to a wider audience than ever before.
A true Marantz, it contains the most advanced circuits in a chassis that's
highly styled to blend with any décor. It's a stunning contemporary
expression of the Marantz "look," long the standard for the entire
home entertainment industry. |
