The preamplifier circuit has been redesigned to enhance spatial expression capability and detail reproduction.

Like the PM-10 and PM-14S1, a high-precision electronically controlled volume is used in the volume circuit to eliminate crosstalk and gang errors between channels.

This volume IC is combined with an HDAM SA3 to form a current feedback type preamplifier circuit. Also included is the Marantz Musical Phono EQ, a newly developed phono equalizer that aims for a richer, more analog-like sound.

This MM-compatible NF-CR type phono equalizer has a two-stage configuration for reduced distortion.

The power supply circuit and power amplifier circuit have achieved an instantaneous current supply capacity of over 45A by adopting a short power line layout and thoroughly reducing impedance.

This enables bass sound reproduction with a sense of scale and instantaneous power.
