Marantz SA-1 550,000yen(February, 2000 release)

The Super-Audio-CD player of No. 1 of a Marantz developed by careful selection part groups including the digital analog converter of the highest precision level.

Every (as a digital analog converter, they are four pieces) two 1-bit dual digital-analog-converter DAC7 (TDA1547) per channel are used,The D-A conversion of a DSD (direct stream digital) signal with the sampling frequency which reaches by 64 times the compact disk is realized.

At the time of compact-disk play, oversampling digital filter DF7 (TDA1307) is used 8 times, the music signal of compact disk with a sampling frequency of 44.1kHz is changed into a bit stream data, and it is delivering to the digital-analog-converter part of 4 tap stream compositions.

Dual HDAM which carried out the twin back of a Marantz and the original high-end device HDAM (high-speed voltage amplification module) is adopted as an audio circuitry. Ideal high slew rate / low impedance are attained by considering HDAM which realized the performance stabilized according to the high shielding structure of suppressing the influence of heat, or an oscillation and electromagnetic waves even on the minimum level as a twin puck.

The super ring-core toroidal transformer with a copper plating shielding cover is adopted as the main power transformer of a power-source part. This transformer has the large capacity of 80VA, and has realized the generous regulation while it reduces leakage magnetic-flux level about to about 1/10.
Moreover, the transformer for exclusive use is prepared for the powering to a vacuum fluorescent tube. Furthermore, the measures against a shutdown of noises, such as a possible, are taken for turning OFF a heater power source besides the data display of the display tube.

The block chemicon of the selection article was specially adopted as the power-source part, and also the part which began to shave and the RCA gilding pin jack, the gilding balance output-terminal, the detachable type AC code, etc. selected carefully is adopted.

In order to eliminate the vibration generated in the oscillation and the interior from the outside, zinc die-casting is adopted as a mechanism and its base chassis, and aluminum die-casting is adopted as a tray, respectively.
Furthermore, the copper plating shielding cover is adopted as a measure against a shutout of the radiation noise generated from the servo system of a mechanism.

While product copper plating made from steel 6.4mm thickness and a base plate with a weight of 6.7kg are used and a die-casting mechanism is fixed firmly, the oscillation, the vibration, and the resonance from inside and outside are reduced by high rigidity.

The aluminum top cover of 5mm thickness is adopted as a top cover, and the case has a structure which eliminated the screw from a front view, the upper surface, and the side.

Playback of the two-channel disk which was equivalent to all the disks (a single layer disk, a dual layer disk, a hybrid disk) which are specification disks of 2chSACD, and was recorded by the device-service-task signal, and playback of compact disk / CD-Recordable disk are also possible.

Aluminum top remote control is attached.
