Marantz proprietary current-feedback circuit, using discrete components, is adopted in the pre-amplifier and power amplifier. It is a high-speed amplifier using the latest technology developed for the higher-grade amplifiers.

HDAM_®SA3 Module

This unit includes the HDAM_®SA3 which had been developed for highend models. The HDAM_®SA3 is incorporated into many components, such as the current feedback power amplifier.

Short-power-line layout

For strong momentary current supply, a short power-line layout unifies the power circuit and output stage of the power amplifier section.
This layout allows connecting the large-current lines via the shortest route while to arranging the left and right channels symmetrically.

CD direct buffer amplifier

An input buffer amplifier exclusive for CD is mounted near the CD input jacks. This is a high-speed buffer amplifier made with discrete components, which avoids interference between right and left channels and can send the signals to the pre-amplifier with very high fidelity.

Block condenser of large capacity

The unit is equipped with a newly developed 15000 μF large capacity condenser that incorporates the concepts of high-end devices into the power amplifier power circuit.
