Topping unveils its DX5, a DAC and headphone amplifier combo benefiting from both an exceptional conception and a resolutely modern design. At its heart is a digital to analog conversion stage carried by a pair of ESS ES9068ES DACs but also an excellent headphone amplifier section based on an NFCA circuit.
