whatever speaker stand you end up with, just a friendly reminder, the speaker stand hole on the S1 is towards the rear which makes it “front heavy” and is prone to fall over unless you position it well on a tripod stand (same direction as one of the legs for example). anyway, i am happy with my stand.
My advice, stick to a normal, aluminum stand. The S1 is top-heavy due to mount located at the rear. I tried smalled stands, didn't care for them. Too much risk for the minor benefit.
