TOPPING DX7s 2*ES9038Q2M 32Bit/768K DSD512 Full balanced DAC & Headphone amplifier XMOS(XU208)+OPA1612 USB/OPT/AES/COAX input

TOPPING DX7s is a full balanced DAC & headphone amp with USB, Coaxial, Optical, AES input and Line Out, XLR, 6.35 headphone and balanced headphone output. Besides, DX7s also have a USB to Coaxial output, you can use it as a digital interface even DX7s is turned off.

DX7s use XMOS(XU208) + 2 x ES9038Q2M + 4 x OPA1612 for DAC, in addition, DX7s use customized drivers(Win 7 or above) from Thesycon, all these factors makes DX7s support 32bit/768kHz and DSD512(Native). You can see the detail info from the 2.23 inch OLED screen while DX7s is working. DX7s use 2 x TPA6120 for balanced headphone amp, providing maximum1000mW x 2@32ohm load.
