TOPPING DX7s DAC/Amp
$499.99
The TOPPING DX7s is a fully balanced DAC/amp and features two ES9038Q2M DAC chips and a more powerful amplifier compared to the DX7. The fourpin balanced out has been upgraded from the DX7 and is rated at 1,000 mW x 2 at 32 ohms and 546 mW x 2 at 300 ohms. For inputs and outputs, the DX7s comes with two XLR outputs, coaxial input and output, and a USB input. It can be paired with a computer or can be used to power an audio setup.
