If there is no danger of the speakers being bumped into then consider floating the speakers on Aurios MIB. Even the original model, now termed 1.0, can create an enhanced speaker performance. If you place one or two granite or marble tiles from Home Depot on your rug to create a level surface beneath each speaker then place one set of three Aurios MIB for $100 used per speaker between the tile and the speaker. This only works if speaker cable is supported so that there is no pulling on the speakers. You can "tune" this tweak by placing a non-rolling isolation block under each Aurios. These blocks are $10 per set of four from Audiogon member Rcreations ( I think this is correct spelling) and consist of ribbed rubber surrounding cork center. There are many discussion threads about coupling versus de-coupling. The Aurios MIB's help many speakers sound better, even if it is so different from the popular spike method.
