TOPPING DX7 Pro+ DAC/Amp

The TOPPING DX7 Pro+ is a DAC/Amp from TOPPING in collaboration with Apos Audio. The original DX7 Pro, which many considered to be the sweet spot in the TOPPING line-up, combined world-class DAC design with powerful amplification in a compact form at an unbeatable price. However, due to extreme volatility in the supply chain during the past 24 months, TOPPING had no choice but to discontinue it. The new TOPPING DX7 Pro+ continues the legacy of this fan favorite. 

DX7 Pro+ vs DX7 Pro?

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. 

Flagship DAC chip

The ESS SABRE ES9038PRO is a flagship DAC chip that achieves ultra-high performance in the audio field. Each channel is arranged in parallel by 4 conventional balanced channels, making the performance even greater. 

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.

TOPPING + Apos Audio

We at Apos Audio have worked incredibly hard to bring the DX7 Pro back–and better than before. We’re honored to have the opportunity to partner with TOPPING as the exclusive retailer of the DX7 Pro+ in the US and Canada. 

No channel imbalance

The step volume control is more accurate than previous designs. Both channels remain perfectly balanced even at low volumes.
