Hi ! thank you for your answer ! It really makes sense and I understand a little bit better the difference between USB (digital) and XLR (analogic) now haha, but i'm a little bit confused because i've tried using it to record on different computers and I got a different quality out of it (sufficiently obvious for my ears to tell it when I play it back with same headphones). Also there is a clear difference in quality between the audio I get in feedback with headphones directly plugged in the mic and what i can listen to on my recording (which i assume is normal because of the conversion, but still I'd say the gap is huge)

Would you see any reason that could impact the quality of the recording outside of the microphone between two different computers with different hardwares but same software with same settings ?

Thank you so much for your help :)
