I use a silk scarf to keep the dust off of my TT.

Visitors are carefully manacled and their children are leashed. No problems so far.
I have a Gingko dust cover on my VPI Superscout/rim drive and with it on, it looks like a museum piece. Company always gravitates to the turntable with smiles. The unit is very well made - fits perfectly, and is beautiful to look at.
A Linn dealer (warning warning) once told me that the dust cover blocked vibrations for ambient sound waves and thus helped isolate the cartridge.

Sounds counterintuitive to me, always did.
i had a vpi hrx which i bought a dust cover for. the only time i used the cover was when i did not use the tt for a long period of time. although i did not always no when that would be. other then that it sat on the floor and was something else to keep clean. i actually came close to damaging my tt while removing the dust cover a few times. to me a non-must!
I'm in the blocks airborne vibrations camp. Maybe it all depends where you keep the table in relation to that crep you're playing too loud, haha.
