Audio over USB via Focusrite Scarlett

So I’m not completely sure if it does something to the audio quality, but…

I just connected my PicoPix to my Focusrite Scarlett 2i2 usb audio interface/external usb sound card. And this works when with internal content, but doesn’t work which external content (as expected). And I’ve played some music through Spotify and I have to say, I think the sound quality is improved in comparison to the same speakers directed connected to the PPM via aux cable.
