Ok guys

You know what I have really had it with you pair of clowns and your arrogant posturing here there and everywhere trying to insinuate that only you know anything and everyone else is sad and pathetic.

Sure I clown around but no freaking way would I be caught spouting off trying to insist that my opinions were the only ones that were correct.

You pair have made these forums extremely depressing and as such I'm done.
Good job boys.....

There are definitely words to describe you Mijo but decency and forum rules prevent me from going there.
Have a blessed day.

Oh and his evil twin rushes to join in.
We are doubly blessed......

It's "only" 82 here today, no need for the AC yet.
But that's a valid point especially if the amount we are talking of is a very small amount, and that I do not know the range of?
When i conducted my test it was fairly mild in the room, low 70,s? Did not feel particularly humid but must be in relation to cooler states.

Alright then
Yes you can tell I am not at work this week as have time to try various experiments but I do think this one maybe useful to some.
Or at minimum another point to discuss?
Re static build up on the record surface while playing.

So we measure static on a fairly regular basis on the films we produce during manufacturing and to this end we use various makes of fieldmeters like the one in this link.

Well I dragged mine out and checked the charge on the record surface while just spinning with no stylus contact and then during and after the full side of an album had played.
Now maybe my meter is not accurate enough to monitor very low level change ( tbh I have no idea what levels we are talking about for the "build up" on a record surface?) but I could measure NO difference in my system in my house with my meter.

So in the spirit of being open minded I tried on my tt-71 this morning with dustcover which is hinged to the plinth both up and down on same tracks.
Now bear in mind this is only on my second system which is not as resolving as the main but still.

Best way I can describe it is that with cover open it sounds more dynamic and open,more air and definition.
With cover down it was not bad by any means but seemed like a veil was lifted when I again opened the cover up.

I cannot perform same test in main system as the cover is a big square that sits over the 401 platter and tonearm and cartridge.

But I would say to my ears in my system it's clearly sounding better open on my Tt-71 which is a cover hinged to the plinth.

Draw whatever conclusions you like.

Well of course its my opinion, glad we resolved that.
Just as it was YOUR opinion that a hinged dust cover should be down.
We all have opinions just like we all have... well , you know.

Obviously you did not realise that your opinion had a counter opinion.
You saw it as having a dust cover so it could be closed to play.
I saw it as having a dust cover to protect from dust when not playing.

Your statement was a definite one that just because it has a hinged dust cover it should be down, I was offering a counter viewpoint.

Where is your problem?

Mijo

Touche!

If the table has a hinged dustcover, it should be down. Look, it's your table...do what you want! I am sure that the reason that manufacturers included a hinged dustcover was so that it could be closed while in use.

Or so that it could be opened to actually place an album on the platter and then play it open or closed and see which they prefer.
Very few absolute black and white ( open and shut) cases where audio is concerned.

But the only true test is to try both ways in your own system as it could give an entirely different result in another persons system depending on a whole slew of factors outside the table and dustcover.

Mijo
It would be nice if for once you could just accept the fact that your opinions are going to differ from other members.
Nobody is arguing that what you state in your system is what you hear and great for you.
However maybe you could just accept that it is in fact just your opinion and not try to foist that off to everybody else here as being gospel.
It works for you and that's wonderful, apparently it does not work for a lot of other members myself included and that should also be wonderful, not an area of contention. 

It does appear that only the users of suspended tables like the SOTA are fully in the camp of dust cover on and down.

I guess I have to say yes and no... Lol.

The lift off cover on my Garrard 401 is only on while not being used to play records so definitely off on that one.

My Technics SL-10 being a linear tracker has to have the cover down and closed to even play so .....
