I would really like to see some measurements for Roland, Mackie (Big Knob) and Rode (AI-1). Not just for the ADC but also for the headphone and line outs.
By the way, there are some great videos by Julian Krause on Youtube who reviewed interfaces like the Behringer UMC22 and 202HD, Steinberg UR22 MKII and UR22C, Focusrite Scarlett Solo and 2i2 2nd and 3rd gen, native or Instruments Komplete 1 and 2. He features frequency response, distortion, dynamic range, equivalent input noise and the gain range for the XLR inputs. Sadfully no further measurements on the outputs, yet.
I'm not sure about his specific setup. But he appears to know what he is doing.
So far I would say that the least interface we need to measure is a Scarlett. We do actually need other interfaces to compare!
