TOPPING DX3 Pro+ Bluetooth DAC/Amp

The evolution of a classic The TOPPING DX3 Pro+ DAC/Amp is TOPPING’s upgrade of their classic DX3 Pro. With a new Bluetooth chip and DAC chip, the Pro+ outperforms its predecessor while also coming in at a lower price point.

The Pro+ has 60% lower THD+N (DAC), 85% lower THD+N (HPA), over 100% more power, and 90% lower output impedance than the DX3 Pro (LDAC version). Bluetooth 5.0 LDAC Hi-Res Audio Wireless and LDAC are supported with a Qualcomm QCC5152 chip. Unlike other DACs that decode Bluetooth codecs with the Bluetooth chip, the DX3 Pro+ uses the ESS ES9038Q2M chip for decoding for even better performance. Plug and play Simply plug the DX3 Pro+ via USB into your PC or Mac to enjoy all the benefits of a high-end DAC without the need for drivers. Only higher-end ASIO applications on Windows 10 require a driver. Low noise NFCA circuit An optimized NFCA circuit provides powerful, distortion-free performance: 1800mWx2 @32Ω, 0.00015% THD+N. High/low gain settings Two gain settings (+6dB/+19dB) make it easy to adjust for the varying impedances of IEMs and full-sized headphones. Four output modes Adapt to every listening situation with the DX3 Pro+’s four output modes: headphone amp, headphone amp + DAC, DAC, and preamplifier. Product highlights
