Roller bearings employed in conjunction with springs provide, as Geoff again correctly postulates, isolation approaching that of the much more expensive Minus K, Newport, Herzan, Vibraplane, etc. platforms.
Stands, to couple, or not to couple, contradicting products and positive reviews
There are many practices/products intended to "couple" a stand-mount speaker cabinet to the floor of a room (spikes, adding mass to the stands via sand/shot, specific bolt-on stands for certain models, etc.). Conversely, there foam speaker pads by Auralex and others, which are intended to de-couple or isolate the speaker from the stand, with rave reviews of audible sound improvement.
So which is right, should I try to "connect" my speakers to the mass of my house, or do I want to "float" the speakers so they are free to resonate on their own?
