The cover has holes in it, so dust will get in anyway. At least with it off you can see and remove the dust, and if you’re bothered put it back, or another type of cover, when not listening
the metal covers are worse as they resonate in a more problematic range then Perspex, although Perspex has its own sonic signature
btw @tattooedtrackman hope you’re also getting some Herbies dampers. And you might also play with footers for under the preamp as well
