Radial Engineering USB-Pro

Very sturdy and robust, most parts you can hit with a hammer without scratching.
Easy installation, no drivers required for MacOS.
Reliable, connect audio device first and every time, without any problems.
No hum and noise perfecly clear sound.

Maybe a little heavy, but that comes with the robustness.
Maybe a little expensive but that comes with the quality.

The sound guy will love you for brining isolated and balanced XLR pair out of your computer.

I use it with AU/VST plugins on my MacBook as a synth rack.

I connect 3.5 mm out to a personal monitor or phones to check my sound before the sound guy unmute my monitor.
