Topping MX3 specs

A digital amplifier with a built-in Bluetooth receiver, DAC, and headphone amp, the Topping MX3 does it all. This versatile, compact unit can be used to power your passive speakers or headphone amp. And in systems that already have a discrete headphone amp (like Toppings conveniently stackable A30), the MX3 can function as a DAC or preamplifier. It outputs an impressive 247 mW of power at 32 ohms in the headphone amp sectiona 190 percent improvement over its predecessor, the VX3, and enough to power demanding headphones like the Massdrop x Sennheiser HD 6XX. Connect the MX3 to your bookshelf speakers with banana plugs or a speaker wire, and itll deliver 38 W per channel at 8 ohms. Featuring a digital display with adjustable brightness, this unit can also be connected to Bluetooth using NFC.
