EK43S Louder than EK43?

Grinders are one of the keys to exceptional espresso. Discuss them here.

So I have been lucky enough to be able to own x2 EK43 grinder. One is the S model and one is the classic.

Both my grinders are manufactured in the same month and year.

However I notice that my EK43S is significantly louder when turned on than my EK43. I thought this could be due to the taller stand of the classic one, lowering the vibrational noise. However, I tried to lift them up while running and I still notice that the EK43S is louder. It also felt a bit more vibrating than the EK43.

The EK43s is aligned with the sanding technique.

What could be the cause/reason for this?

I'd like my EK43s to be as quiet as my EK43...
