Topping proposes with the DX7 Pro+ DAC and headphone amplifier, a direct evolution of its predecessor, the DX7 Pro. Thus, this new model benefits from an improved architecture with updated components, allowing an improvement of the overall performance of the device. Its design has also been modernized, now displaying softer curved edges.

Integrated NFCA amplifier

The NFCA headphone amplifier of the DX7 Pro+ has been specifically optimized for this model, offering very low distortion and noise levels. In addition, it provides a nice power reserve that allows it to work equally well with high sensitivity IEMs or high impedance headphones. Still in this optics of adaptability, the device proposes two adjustments of gain.

Balanced & single-ended headphone outputs

As for its headphone outputs, the DX7 Pro+ offers three different formats, in order to adapt to different needs and equipment. There are two balanced outputs with XLR 4 pins and 4.4mm jack, and one single-ended output with 6.35mm jack.

Selectable line output

The DX7 Pro+ has line outputs in XLR balanced and RCA single-ended format. It is thus possible to select to use only the XLR output with the "XLR Only" mode or RCA with the "RCA Only" mode, but also to activate both simultaneously with the "XLR+RCA" option.

I2S input

The Topping DX7 Pro+ integrates an I2S input using the HDMI connector and allowing to transmit the signal to the ES9038Pro DAC in the most direct way possible. This input supports PCM streams up to 32bit 768kHz and Native DSD up to DSD512. The I2S input provides settings for phase, DSD channels and the ability to select the pin for the DSD indicator. These settings allow the DX7 Pro+ I2S input to be compatible with the vast majority of devices using I2S via HDMI.

Tube / Transistor simulation

Borrowing the sound signature of tube and transistor audio systems, Topping has created a system that simulates both in a single device. It is thus possible to enjoy three different listening modes: standard, tube and transistor.

12V Trigger

The DX7 Pro+'s convenient 12V trigger input and output allows for active control (trigger output) or passive control (trigger input). Using only a 3.5mm jack cable (sold separately), the DX7 Pro+ can be turned on and off automatically in full synchronization with other devices equipped with a 12V trigger interface.
