I don't know.........is there something I should know about here????
From the Pro-ject Audio Systems turntable FAQ:
"Removing the dust cover generally improves replay quality, as the large lid surface captures airborne resonance's and transmits them to the chassis or plinth. This applies equally if the cover is not removed completely but left open during replay."
So, I guess it's a matter of degree of degradation.
