AMS-44 : Tiny (great) but limited

Four inputs in such a small/cheap package- amazing. Usb-c: great. Music and sound quality: great. If you just want to feed four channels into a DAW like logic and nothing else: great. But there are a bunch of big limitations: functionality wise it is a big step down from e.g. a focusrite.

Cheap plastic lightweight build quality: quite bad.

Not being able to mix input (clicktrack?) with monitor levels is a deal breaker for me.

Not having 48V phantom to power condensor mics is an even bigger dealbreaker.

You cannot mute channels, you cannot choose which channels appear on your monitor/headphone and there is no separate gain for your line out and headphone (there is one control for both which is a big problem in any live situation). Also in 'music' mode inputs 1/2 -> output A, 3/4 -> output B which means you cannot monitor all tracks from one channel which is absolutely unhelpful.
