Review: Topping DX3Pro+ LDAC Headphone Amplifier

For my newly built Windows 11 PC, I initially planned to install an Xonar Essence STX PCIe audio card, but it is no longer manufactured. As a replacement, I decided to purchase a standalone DAC and headphone amplifier to use with my Sony MDR-7506 headphones.

I had read very positive review results on the Topping DX3 Pro+ on the AudioScienceReview website, where laboratory measurements are done in a controlled environment.

I really enjoyed the DX3 Pro+ DAC headphone amp, but I replaced it with the slightly better Topping DX5 II DAC/headphone amp. 

I found no issues in Topping DX3 Pro+. It worked out of the box and sounded beautiful. The amber display was clear. It went to sleep and woke up automatically.

USB/ASIO Driver for bit-perfect playback in Windows
  • Official TOPPING downloads page — that’s the canonical source for the unified USB/ASIO driver. Look for the “V5.74 driver for most of TOPPING DACs” (or the newest driver listed):
Topping DX3 Pro+ Firmware
  • The DX3 Pro+ firmware/update page also links to the required drivers/tools for Windows — useful if you’re updating firmware too:
