|Summary||Topping D3 Multi-function DAC with Headphone Amplifier
The Topping D3 is an audiophile machine. It incorporates 24 bit/ 192kHz DAC sampling with a powerful headphone amp. Topping uses hi-fi electronic components like an ALPS potentiometer, KOA resistors, capacitors from Nichicon and WIMA, and transistors from Toshiba. The sturdy aluminum case makes the build quality excellent and a gives it a sharp appearance.
Audio signals are sent to the D3 in many ways. The back of the unit includes left/ right RCA inputs, a USB input, and three S/PDIF inputs; optical, RCA, and BNC. This makes connecting the Topping D3 incredibly adaptable to most situations. The front of the case features an input selection button, power button, 1/4″ headphone input, and volume knob. Sampling bit rates are fast at 24bit/192kHz all while keeping distortion low. The integrated amplifier is powerful, with the ability to drive headphones between 16 Ohms-600 Ohms. With both pieces of equipment in one box, the Topping D3 is an irresistible addition to any audiophile’s list of gear.
