Parameter：
Using the original Marantz direct engraved line design, restore high-fidelity tone
Using the original JRC5532 op-amp
The filter circuit adopts Nikon 3300UF/25V*6, part of the capacitor adopts audiophile German Weimar, the sound is natural, the sound field is wide
Resistor selection of the main circuit using the accuracy of 1% of the five-ring metal film resistor, to ensure a good signal-to-noise ratio of the machine.
PCB using 1. 6 mm thick double-sided plate, 2. 0 ounce copper thickness gold-plated full process, to ensure that the size of the current through the good performance. First-class PCB quality. The entire circuit reference Marantz famous machine design, alignment layout is quite rigorous and reasonable, the overall PCB alignment using a point grounding method.
