Topping DX7 Balanced DAC/Amp
Fully Balanced DAC & Headphone Amplifier
It’s not often that a fully balanced DAC/amp comes along at a price like this. Featuring a four-pin balanced connection on the front, the Topping DX7 is ideal for driving headphones like the Massdrop x Sennheiser HD 6XX with a balanced cable installed. Along with being a great pairing with a computer, it can be used as the center of an audio setup and features two XLR outputs, a coaxial input and output, a USB input, and an included remote control. This all-in-one unit uses XMOS and dual ESS DACs and a four-channel amp program, and supports up to 384kHz/32bit PCM files and DSD128. Complete with an OLED display, it can run either 110V or 220V and has a power mode switch on the left side.
Note: At checkout, you’ll have your choice of color: black or silver. This drop is limited to 200 units.
