DAC/Preamp Topping D30PRO

Topping D30Pro is a digital-to-analog converter with a preamp in one unit. Audio equipment has two outputs with the possibility of parallel signal output. An internal MeanWell power supply is provided, operating at an input voltage of 110-240V.

 

Topping D30PRO DAC/Preamplifier Overview

 

In this model, Topping has abandoned the use of AKM and ESS chips. Instead, I used two pairs of CS43198 chips from Cirrus Logic. The result is the implementation of a balanced scheme. Thanks to full-fledged 8 channels operating in parallel, it was possible to obtain high performance. It looks like this:

 

  • THD: no more than 0.0001% (1kHz).
  • Signal to noise ratio: approx. 120 dB (1kHz).
  • Dynamic Range: 128dB (1kHz)

The device has an output voltage of 2Vrms and 4Vrms for unbalanced and balanced output respectively. As well as low noise level, which is less than 0.9uVrms and 1.1uVrms. These parameters perfectly characterize the D30Pro as a preamplifier. active acoustics.

Advantages of Topping D30PRO

 

One of the main advantages of the D30Pro is the presence of CPLD. It is a programmable logic integrated circuit. Its goal is to combat jitter by processing clock pulses and then optimizing the signal. The effectiveness of this solution has been confirmed both by the developers of the device and by independent experts.

The USB connection is provided by the XMOS controller model XU208. It has custom Thesycon driver, supports Hi-Res (PCM 32bit/384kHz and DSD256) and ASIO. Windows 7 (and above) and macOS systems do not need to install a driver. That is, they can work on the principle of Plug and Play.

The included remote control allows you to not only adjust the volume, but also select the active input and output. This is very convenient when connecting multiple devices to the D30Pro.
