It’s not often that a fully balanced DAC/amp comes along at a price like this. The Topping DX7s improves upon the well-regarded DX7 by taking both the DAC and headphone amp sections up a notch. It features two ES9038 DAC chips and a more powerful amplifier—especially the four-pin balanced out, which is rated at 1,000 mW x 2 at 32 ohms and 546 mW x 2 at 300 ohms (compared to the original DX7, which outputted 420 mW at 300 ohms). Equipped with two XLR outputs, a coaxial input and output, and a USB input, the DX7s can be paired with a computer or used as the center of an audio setup. It can run either 110V or 220V, has a power mode switch on the left side, and is complete with an OLED display.
