What is vibration isolation for?

many users laughed at component isolation & vibration control until they tried it for themselves - I was one of those myself, until I tried it.

price? Who even looks at the price? No true audiophile considers anything but the sonic improvements as long as there's food on the table & a roof over one's head :-)

beautifully explained Audiophile9: but somehow I also get the feeling that some others will never hear you - not because they cannot, but rather because they choose not to...

While not caring at all about what the ignoramuses continually espouse above, I only tried to answer the originally posted question based upon my own experiences. Yes the stuff works, no we don't always understand why.
But what bothers me is that the poster is being so misinformed with absolute disinformation being posted by the absolutely clueless, who claim that they "know it all", "it can't possibly work because I don't understand why", " those who have experienced improvements are imagining it all because they spent the $ but I didn't".

Crp raises some very legitimate issues; I'll share my experiences in that regard.
My floors are concrete & outer walls are cinderblock - very "dead" stuff indeed. Previously when I used a soft / flexible base under the speakers, there was enhancement of perceived bass but at the expense of articulation (some call this 'sloppy' or 'loose' bass; an accurate description.
Changing to spikes atop the concrete actually enhanced deep bass extension, improved articulation across the full frequency band, & reduced some resonance issues.
