High quality sound

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 technology developed for the higher-grade amplifiers.

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 phono equalizer.

It is generally known that the sound quality is not necessarily the same even if amplifiers have the same specifiations. Marantz considers the cause to be the power to drive speakers. The power amplifier of this unit has the ability to momentarily supply current of 45 A or more to drive speakers strongly.

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.

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.

As a phono equalizer amplifier for MM cartridges, new phono equalizer circuit has been developed for PM8006.

The unit is equipped with a toroidal power transformer to minimize vibration and leakage flux specific to the transformer. Especially to reduce leakage flux, which affects sound quality, the periphery is doubleshielded, using a core ring and a short ring.

The unit is equipped with a newly developed 18000 μF large capacity condenser that incorporates the concepts of high-end devices into the power amplifier power circuit.
