dustcover up, down or off


To get the best sound from a TT, should the dustcover be up, down or removed all together? I have always removed my dustcover, but I recently read an opinion that having it in place prevents unwanted vibrations from the speakers from reaching the TT. What are your thoughts? Thanks.

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.
My Indian Medicine Man (retired) who is regularly hired from me for a dance around my turntable, says: "It depends..."
"Off, but with an acoustical screen around the TT."

Yes, I think I saw this on "Star Trek: The Next Generation" once when Geordi was playing his vinyl. He did not care for digital!

Seriously, I've seen tt covers that surround and enclose the entire table without being attached. I really like that idea!

Actually Mapman, that is a good solution, but they tend to be heavy if properly constructed, making them a PITA to use; and really not any better than a hinged cover if the TT is, or can be, fitted with one (not always the case these days ;-) In addition, they need to be fitted with some kind of resilient material around their bottom edges so they don't potentially rattle against the shelf ;-) The bottom edges of even hinged dustcovers should land on something resilient and not right on the plinth.
