The V/I converter circuit, which is the key block of the current-feedback pre-ampliﬁer and power amplifier, is equivalent to the HDAM-SA3 amp- module developed for such higher-grade models as the SC-11S1.

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

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 double-shielded, using a core ring and a short ring.

It is generally known that the sound quality is not necessarily the same even if ampliﬁers have the same speciﬁcations. 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 25 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.
