High quality sound

The HDAM_® SA3 is a key amplifier module for current feedback amplifiers. It is installed in the voltage to current converter, the most crucial component, to improve the stability of the circuit and provide high-speed sound.

The HDAM_®SA3 is combined with a JRC volume IC to achieve low distortion and high S/N. A range of volumes between 0 and -99.5 dB can be smoothly controlled in ±0.5 dB steps.

The power amplifier contains a Hypex NCore_® switching power amplifier module. This switching amplifier module minimizes distortion from bass to treble and frequency characteristics are not changed by the impedance of the speakers, achieving extremely high performance. It can be used with a high-speed pre-amplifier circuit containing the HDAM_® SA3 to faithfully and precisely convey the finely detailed information in DSD and high-resolution sound sources.

The new Marantz Musical Premium Phono EQ phono equalizer has been developed for MM/MC cartridges to produce rich sound that is more similar to analog. This circuit contains a new feedbackless equalizer amplifier and MC head amplifier developed by HDAM. J-FET input is used, enabling the input coupling condenser to be eliminated. This improves the purity of the signal path in the small signal section.

High sound quality parts are used in every part of the circuit, including high sound quality MELF resistors and film capacitors.
