TOPPING MX3 Built-in Bluetooth Receiver DAC Headphone Amp Digital Amplifier

The Topping MX3 consists of a DAC, an Amp, and a bluetooth receiver that can easily power a headphone amp or a set of passive speakers. It produces 247 mW of power at 32 ohms as a headphone amp and 38 W per channel at 8 ohms for speakers. The MX3 is very versatile and can be used as a PC power amp, a headphone amp, a bluetooth amp, a bluetooth receiver, a power amp, a DAC/preamplifier, and an amp for a digital player.
