Topping D50-III

The Topping D50-III has a Qualcomm QCC5125 Bluetooth chip for superior wireless reception. It supports Bluetooth aptX, aptX Adaptive, aptX HD and LDAC codecs. Topping decided to offer the possibility of working as a DAC/preamplifier with volume control, in combination with active speakers or a power amplifier. The connection interface of the DAC D50 III contains numerous digital inputs: SPDIF coaxial, optical and USB-C. Outputs include a balanced 6.35 mm TRS jack and an RCA output. it has an attractive display, Bluetooth remote control and 10-band equalization software enhance the user experience.
