I second (or third) the opinion that every stand-coupling method will yield a different sound in a resolving system. With my Harbeths on Skylans, Herbies Dots were by far the best. With my Operas on Targets, Blue Tak sounds the best to me. Keep in mind that some of these couplings that do not firmly fasten the speaker pose the danger of the speaker being knocked off the stand by a running child, so keep it in mind if you have kids around.
