Topping DX3 Pro+, the multifunctional DAC/AMP, is an updated version of DX3 Pro. It can work as a standalone DAC, preamp, or a headphone DAC/AMP through Optical, Coaxial USB, and Bluetooth inputs.
DX3 Pro+ uses ES9038QM decoding chip and 2nd generation 8 core XMOS XU208 for USB input. And it adopts the newest QCC5125 chipset to support LDACIAAC protocol, has the certification of Hi-Res Audio Wireless and LDAC. The NFCA circuit in DX3 Pro+ is optimized for better performance, giving ultra-low noise and distortion. Compared with the previous LDAC version, DX3 Pro+ has the same functions but comes with much lower THD+N and higher output power performance.
USB input supports up to PCM 32bit-768kHz and DSD512 native, DX3Pro+ also has a wide range of compatibility, Windows 10, MAC, Linux, iOS, Android can be plug and play. Even in the face of higher-end ASIO applications, DX3 Pro+ can driver-free MAC and Win10 with customized Thesycon ASIO drivers.
DX3 Pro+ has 4 output modes: Headphone Amp, Headphone Amp+Line out, DAC, and Pre-amplifier. TOPPING optimized the NFCA (Nested Feedback Composite Amplifier) circuit for DX3 Pro+, which can provide excellent AC & DC performance and pair with high sensitivity IEMs and power-hungry high impedance headphones nicely. And also it provides two gain settings, which greatly expands the range of headphone adaptation.
Stacking DX3 Pro+ with PA3s power amplifier with RCA, they share the same spatial dimensions and easily match. When used with DX3 Pro+, the TRS balanced input of PA3s is available to be used with other audio sources input. The output power will be 80W X 2@4Q, 10% THD+N, 65W x 2@4Q, 1% THD+N.
