Kalite, are you planning on mounting your S3as horizontally or vertically?
If vertically, then you might conceivably get away with the stands you link to, but horizontally? Forget it. dfegad
Sure, they'll sit on the stands (just), but in terms of stability, stereo imaging and (lets not forget) safety, you'd do as well mounting them on a stack of jello and remembering not to cough too loudly in their general direction.
These are HEAVY speakers, and require a stand that isn't going to take a nose dive when it's got 16kg of wood and metal on top of it. That means something that either has a larger footprint than the speaker and / or (preferably and..) is heavier than it. None of which the stands you mention come close too....Without that, your sphincter's going to be clenching every time someone brushes past them, leans on them, jesus, even just LOOKS at them.
If you're going to splash a not inconsiderable amount of cash on such damn fine monitors, at least do them (and yourself) a favour, and do them justice with some heavy duty stands. If you've got the time and inclination, it's cheaper to make some stands, or get your friendly DIY-mad buddy to do it for you. I knocked up a pair in an afternoon; 16mm MDF boxes each filled with 50kg of sand, sat on top of 25kg concrete slabs. Spray paint them black, set them in the correct position in your studio (preferably before you fill them with sand....) and you're in business. Total cost for me was about $100
