NAD D 3020 V2 vs Marantz HD-AMP1

Marantz HD-AMP1 review

This unit delivers 20W/8 Ohms of power vs 30/8 from his opponent. The device is made on a two-layer chassis with an additional bottom plate, which effectively dampens any mechanical vibration that can degrade the sound. The HD-AMP1 is the first Marantz model in this class to use pulsed amplification technology. The company's specialists for a long time radiated class D circuitry, setting themselves the goal of achieving with its help sound quality that meets Marantz's high standards. As a result, using proprietary HDAM modules and a specially calculated general current feedback, it was possible to create a class D apparatus that is capable of working with speakers with a wide variety of impedances and has real Marantz sound.

NAD D 3020 V2 review

The aptX Bluetooth module is built into the amplifier, so signal transmission from various mobile devices will not cause any difficulties. It is also very useful to have a 3.5 mm output for connecting headphones on the front panel. Something was added on the rear panel of the new amplifier. The D3020 V2 received an output from the preamplifier and a connector for connecting a subwoofer (the necessary adapters are included), as well as a control 12-volt trigger input. In this model, NAD has installed Class D amplifiers, which it has preferred lately.
