OT - sound quality

Sure. Even paramount headroom can be exceeded and on the OT you really have to pay attention.
Leave headroom (track levels and volume settings), insert effects can degrade the sound if overdubbed again and again and again…(easy test to check and can also be expoited in creative ways) most notably the filter and lofi - even at neutral settings.
The effect might be subtle, but the it´s there.
If you don´t use them on a track get rid of them. Input meters mostly yellow-orange-y, red at peaks is ok.

Here are a few links that deal with gainstaging and levels:
