Thank you very much Chris and everyone else, that puts my mind at ease.

The speakers are active (KRK RP5), so no amp in between them and the
audio interface. But since the audio interface should be able to handle
it without issue it's not a problem. Additional gear, e.g. a small
mixer, would add convenience to my setup, but it's not necessary at
this point.

Thank you very much for your helpful answers.
Best regards,
Philipp
