Dust cover up or down?

It is true the cover may transmit air-borne vibrations to the stylus/disc interface.

But it may also be true that it shields that interface from those vibrations by acting as a a barrier whose micro flexures absorb them.

Anyhow my TT has no cover so I can't hear it.   Plus it doesn't seem to become inordinately dirty.

I think many audiophiles over-analyse.  That is ANAL ise.

And hands up please anybody who has observed any tracking weight variation at all with lid up or down using an electronic scale that measures to 0.01 gramme??

So let's kill that one right off.

Art Dudley was one of the nice guys and a great writer, but an arch-tweaker and inclined to believe the voodoo.

I've just re-read the thread and as I thought, no-one said they had measured a difference in VTF.  Two said there might be a difference.

So far then the score is nil posters have measured any difference.  We've all got those digital scales, so why not get down to it - a minute or two's effort.  I would certainly try, but I don't have a dust cover.

The subject is interesting because this is one pretty stupid tweak where a scientific measurement can easily be made, and proven by weighing with cover off and then doing it again to test the scale is true.  I'm putting my money on 'no difference'.
