Plug and play

DX7 Pro+ has a wide range of compatibility: Windows 10 and above, MAC,Linux, IOS, Android can be plug and play. DX7 Pro+ uses 2nd generation 8 coreXMOS XU208, USB supports up to PCM32bit768kHz and DSD512 native.

 

Flagship DAC chip

DX7 Pro+ uses ESS SABRE ES9038PRO, with 32bit Hyper-stream architecture, achieves ultra-high performance in the audio field. Each channel of the DX7 Pro+ will be arranged in parallel by 4 conventionall balanced channels. This makes the performance of DX7 Pro+ even better.

 

Brand-new I/V conversion circuit

TOPPING designed brand-new I/V conversion circuit with better audio reproduction. The unique circuit design provides lower distortion and lower noise while occupying less space.

 

All-new design

TOPPING has redesigned the DX7 Pro+ inside and out. Not only will it feature TOPPING’s ultra-clean NFCA module and updates to the audio circuit, but the chassis design is based on the Red Dot Award-winning design of the TOPPING DX5. The DX7 Pro+ outpaces its predecessor in category after category. It uses the most up-to-date Bluetooth 5.1 chip with LDAC support. It also has 70% better noise performance, 100% stronger output power, and 99% lower output impedance.
