USB Soundcard Recommendation

[Gdillon]

Hello, I'm setting up a new install of REW and would like to use an external sound card. Doesn't have to be the best but something nice. I will be using REW primarily for loudspeaker design, so both frequency and impedance measurements, Any recommendations?

The RME ADI-2 Pro is excellent for impedance measurements as it is DC coupled and its headphone outputs have high drive capability. It doesn't have mic preamps though. More general purpose interfaces with mic preamps include the Focusrite Scarlett 2i2 and the Steinberg UR22C.
