Design & Build Quality:

The SMSL D1 High-Resolution DAC is a compact device, measuring 101 x 33 x 90mm (W×H×D) and weighing approximately 201.1g (0.443 lbs). Its construction utilizes an aluminum alloy casing paired with an acrylic panel on the front. The unit’s size and weight are suitable for integration into a desktop audio setup.

The front panel of the D1 features an acrylic surface. The SMSL logo is positioned centrally. A touch-sensitive input selection button is located on the left side, allowing users to cycle through Coaxial, Optical, and USB inputs. LED indicators illuminate to denote the currently active input. On the right, a touch-sensitive power on/off button controls the device’s power state.

The rear panel of the D1 provides various connectivity options. It includes a pair of RCA outputs, labeled “R” and “L,” for single-ended analog audio connections.

Digital input options consist of Coaxial and Optical ports. Additionally, there are two USB Type-C ports: one designated as “USB Input” for data transfer and another for “Power Supply.” This dual USB-C configuration enables the device to receive power independently via a 5V USB power supply, while also connecting to a source device for audio data. The connectors are gold-plated.

The top surface of the D1 is a plain, smooth aluminum panel. It does not contain any markings or logos.

The bottom of the D1 is equipped with four small rubber feet. These feet are designed to provide stability and minimize movement on various surfaces. They also contribute to minor isolation from vibrations. The underside has a matte finish and lacks additional markings.

The SMSL D1’s construction involves an aluminum casing and an acrylic front panel. The device exhibits a substantial feel, and visual inspection does not reveal significant manufacturing defects such as gaps or burrs.
