Rega TT Dust Cover Vibration


I have a P25 and recently while playing LPs loud (not ear busting, just loud enough) I discovered that the dust cover was vibrating quite a bit - enough to impact the playback. Anyone else have this issue? Short of taking the cover off, is there a way to defeat this gremlin??

After almost two years of resisting, tonight I removed the hinged dustcover from my turntable. I sensed less congestion in the lower mids, and a lower noise floor.

Would this be consistent with playback with the dustcover removed, or is this wishful listening?
I don't think it is wishful thinking - it is real. Especially when enjoying a long session at a good volume level.
