Description

The unique HDAM-SA3 circuit of Marantz can provide the amplifier with a wider dynamic range and lower distortion output. Combined with advanced current feedback technology, even when reproducing large dynamic music segments, there will be no distortion while displaying strong bass impact, and clear, precise original sound and outstanding vocals can always be reproduced!

The only original style on the entire website, using imported discrete transistors and current feedback technology throughout the entire version. The modules are buffered, amplified, and filtered in three stages.
Gain: 5 times

preamp board works voltage: +/-DC12V to 22V regulated
if you buy it with our power supply board. the Power board recommend Dual AC20- 25V
PCB Size:10cm*7cm
Adopting 4-layer gold-plated PCB

The HDAM-SA3, a separate circuit board independently developed by Marantz, replaces ordinary integrated operational amplifiers. HDAM-SA3 adopts separate independent components and shorter left and right mirror signal paths, which performs significantly better than conventional integrated operational amplifiers, achieving excellent voltage conversion rates and noise levels, allowing the amplifier to produce more dynamic, accurate, and delicate sound.
