Unboxing and Initial Impressions
The SMSL RAW-HA1 arrived in a well-packaged box. Inside, I found the unit itself, along with a user manual (available in both English and Chinese), a full-function remote, cables (HDMI, USB-A to USB-C, and a power cord), and a Bluetooth antenna.

The initial setup was straightforward. The included cables made connecting the RAW-HA1 to my PC and speakers effortless. The remote is a welcome addition, providing easy control without needing to reach for the unit itself.

The rear panel is well-equipped with a variety of inputs and outputs, including optical, coaxial, HDMI ARC, USB-C, RCA line-in, and a subwoofer output. However, notably absent is an RCA output for external preamps.
