I might take a bullet for this, but your question contains the answer. You’re already aware that your upgrade is clearer and more precise. That’s good for mixing and critical work.
So make an EQ preset for mixing, and make a separate EQ preset for enjoying your music. The latter doesn’t need to be ultra precise, just pleasant to your ears. Match it to your previous setup or go further. Entirely up to you.
Hot take here, but I keep turning back to Sade or Norah’s debut album every time I need to judge the ‘musicality’ of any new equipment. I know there are more revealing tracks out there for this purpose, but these are my cohesive, immersive go-tos for judging the ‘stuff’.
