So, this is the simple device, which is conceived to do the simple job - adjust the volume of active speakers. The box is sturdy, everything looks good and reliable. I also noticed no sound coloration or any other issues.
Pros
TRS outputs - I like them, because my both audio interfaced has the same, and thus, when changind setup I can reuse my cables+connectors.
Sturdyness and simplicity
Hybrid inputs (TRS/XLR) - great universal solution.
I like the design as well. Also, would appreciate a white/silver version.
Cons
Well, actually nothing, except the volume knob is a bit too firm while adjusting.
