Are Dust Covers a MUST

Thank you

The dust cover creats a resonant cavity. Always try the TT with and without the cover to see which sounds better.

"I like it with cover on"

I should add, 'thus far'. As I am still experimenting. I just got cover (custom shape) made and delivered on Christmas Eve. BTW my cover rests on TT plinth/stand. May be the cover acts as acoustic receiver and adds/impacts to the TT's vibration control (system).
I'm sure Gingko products are top quality but charging $300 for a piece of acrylic is absurd. Got mine custom made for $75 including cutouts for the tonearm that protrudes beyond the plinth of my Scout slightly when resting. The shop owner told me there is absolutely no good reason why an acrylic dustcover should cost $300. No kidding.
I've heard both side of the argument but I can't get past the mental image of a vortex of dust particles raining down on my albums. Dust cover on and down when I'm playing LPs.
I am coming very late to the party here, but the guys that make these products have to pay employees, pay the light bills and pay the rent plus buy the raw materials, shop supplies and pay equipment depreciation & transporation cost plus make a profit...I think a professionally made at $300.00 dust cover from Gingko is a steal..

I just ordered a custom Cloud 11 and I think it is quite a bargain compared to many of the $$$$ overly inflated and often ineffective products out there..My 2 cents
