I've heard many a more mid-fi perhaps setup over the years produce audible, power draining, and clipping causing feedback with cover up and not with cover down, especially in lively rooms with warped records and no low pass filter.
Down is safer in this regard. THat's all I'm saying
I have not had this happen ever since acquiring the Linn Axis 20 years ago.
Higher end rigs are most likely inherently mre resistant to this so I would agree it is probably an issue with some tables and nt others.
I like the Linn better currently with the cover off, but still leave it on and down 90% of the time,
I have in wall wiring runing to speakers in other rooms, so it is pre much a non issue when listening there.
