{"type":"firestarter.listing","listing":{"id":"lst_cSPiNxC5","product_name":"TOPPING DX3 Pro+ Bluetooth DAC/Amp","category":"Headphone DAC/Amp","description":"The evolution of a classic\nThe 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). \nBluetooth 5.0 LDAC\nHi-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. \nPlug and play\nSimply 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. \nLow noise NFCA circuit\nAn optimized NFCA circuit provides powerful, distortion-free performance: 1800mWx2 @32Ω, 0.00015% THD+N. \nHigh/low gain settings\nTwo gain settings (+6dB/+19dB) make it easy to adjust for the varying impedances of IEMs and full-sized headphones. \nFour output modes\nAdapt to every listening situation with the DX3 Pro+’s four output modes: headphone amp, headphone amp + DAC, DAC, and preamplifier.\nProduct highlights\n\nESS ES9038Q2M DAC chip\nLDAC audio\nTHD+N:
