I always appreciate your enthusiasm for Technics tables and vinyl playback. I keep the transparent hinged dust cover on a KAB mod’d SL1210M5G down and have no problem seeing the record currently playing. Even with nothing on the platter, leaving the cover in place limits dust reaching the mechanicals of the turntable and should keep the mat cleaner too. FWIW - in addition to changing the stock feet to threaded spikes resting on a heavy wood platform with layered isolating materials under each corner, I also use small gel "bumpers" on the plinth where the dust cover will rest when lowered. Finally, a weight is placed on the top of the closed cover during playback.
As Mapman has already said in response to the OP’s question...up or down? Try it both ways and let your own ears decide.
