Are Dust Covers a MUST

The higher resolution your system is capable of, the easier it is to tell the positive effect.

Vtvu, do you have a website or link to your products?
I know Ginko makes dust covers, costing $250+. There is one audiogon seller selling it at $175+.

I just use a plastic printer cover over the whole TT when not in use, to keep the dust off. I think it was $3.99 on e-bay, for 2 (so I have a spare if this one rips in a couple of years - ha!).

I like dust cover primarily for protection from Dust, prying hands or accidents.
As far as sound with the dust cover on,in my experience, it definitely changes the sound towards warmer side. If you had edge before, it would likely go away. If you had warm sound, it would change to warmer. It is almost like you changed your phono cable

Which one is right? The one you like!

I like it with cover on.
