My couple words. In old days inputs was CD, Tape, Tuner, so we know what is where connected. Caiman has three types of inputs - usb, optical and coaxial. I usually look for a name of input when selecting, I have different equipment conected to different type of input. If we have only two types and they are two of each, name of input type does not help much. I will need a number or I just remember where what is. We can keep a name of input type for aesthetic reasons if we need, but it will not help to identify particular input.
