Marantz PM-94Limited 260,000yen(around the 1988 time)

The limited model which drove the tone quality into the base for PM-94 centering on the construction or the material side.

The power element MOS FET is carried in the output stage.
The output stage of a MOS FET triple push pull stream composition and the combination with an original circuit technology "Quarter A" form a pure Class-A and AB class into an auto shift by electronic control, and drive a speaker powerfully from Loule Bell to a high-level.

The compact disk/Phono direct position is carried for a pure and quality music play. Moreover, he recorded MC transformer and has promised the tone quality of advanced MC cartridge.
Furthermore, it has a position only for HiFi VCR, and corresponds to the AV source.

PM-94 is improved from a material side and the more advanced tone quality is pursued.
The new materials "raincoat tightness" of a copper plating copper plate are continued and adopted, and also a nonmagnetic material is stuck on a vibration fraction, and the up of the vibration variance by a heterogeneous alloy junction and an intensity is performed.
Moreover, the conventional top plate made from a steel plate was changed into the aluminum drawing-out material of non-magnetic material, and the cross interferencee by the eddy current is banished.

In order to suppress the oscillation and vibration from the outside, the thorough measure against vibration proof, such as filling up the room inside a large-sized insulator with Portland cement, is implemented.

The power-source part is performing power-source serious consideration thought of Marantz tradition, and is constituted centering on the large-sized toroidal transformer and the large-sized electrolytic capacitor for HiFi audios of special edition.

The repetition of the part selection by a hearing and tuning etc. is finished in the tone-quality first priority to the detail.
