Hello Mark, I did not suggest leaving the dustcover up while listening, if anything, I would think that would make matters worse, internal vibrations and such. What I did suggest was removing the dustcover completely while listening. I'm no expert but I thought it was common knowledge that the closed dustcover causes unwanted vibration. I know that my turntable manufacture (Pro-Ject) recommends removing the cover while listening. I even removed the hinges. I would think that is why so many high end models, Basis, VPI, just to name a few, offer the dustcover as as option. Think about it, your enclosing all that super sensitive stuff under a plastic lid resting on a solid platform. That can't be good. Again, let me state that you guys know a lot more about this hobby then I do but I tried it both ways and it just sounds better with the dustcover removed while listening. Thanks for your recommendations on the static in potentiometers.
