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.
