Closer and Inside Look (EB03)
The Silverstone EB03 headphone amplifier also has a blue LED power indicator like the EB01-E. In the front is also a 6.3mm jack plug.
The EB03 also has a very solid aluminum casing with aluminum feet.
At the rear are the input and output ports along with the power input socket and power switch at the right-most portion on the image above.
Like the EB01-E DAC, the EB03 headphone amplifier also has the same brushed aluminum finish on the top aluminum panel. The volume knob is plastic but has the same aluminum-like finish.
The knob itself is solid metal and is not a cheaper plastic component, certainly to keep up with the quality of this hardware.
The EB03 headphone amplifier also has aluminum feet with rubber pads.
