Fosi Audio ZD3 Bluetooth USB Desktop DAC ARC Input, ES9039Q2M Fully Balanced Digital Decoder for Stereo Amplifier with Remote

With extended use, the device proves reliable. Users report that it does not overheat even during several hours of listening, switches between inputs without issues, and operates without noise. HDMI ARC works without additional setup on Samsung TVs and other brands, with volume controllable directly from the TV remote. Some users noticed that sound improves after the device warms up. The operational amplifiers are replaceable, and several users have experience swapping them for higher-quality variants.

The main complaint concerns Bluetooth connectivity — several users report that range is limited (around 2 meters without dropouts) and sound quality over Bluetooth is average compared to USB or optical input. Some also mention that HDMI ARC requires a high-quality cable (2.1 or higher), otherwise sound drops out. One user noted that the cheap power adapter included may not be ideal for maximum sound quality. Critical reviews account for less than 2 percent.
