The resurrected thread!
Since this has been brought back to life, I'll add something for those ending up here after an internet search: the partially inflated inner tube idea can be bettered by placing compression springs under the component instead of an inner tube. I find the inner tube muddied the sound, while springs brought all the benefits of isolation without the muddying effects of rubber.
You can buy springs cheaply online at Grainger, for instance. Calculate the load you'll need by dividing the weight of what you're trying to isolate by the number of springs you want to use. Less is better, so use 3 or 4. Then look up springs wth that load. Purchase compression springs with a diameter of at least 1/2" so they are stable. Also, it's better to have a slightly longer spring with a lower spring rate than a shorter sprong with a higher rate
