The only device that needs isolation is the turntable. The best come so equipped like SME, Sota, Dohmann, Avid and others. Everything else could care less. It is just audiophile mythology.
Why spend more than $25 per piece of equipment on vibration reduction?
Do products more expensive than Vibrapods ($24 per set of four) provide superior isolation? I've been pretty happy with the pods, but I wonder whether spending somewhat more, e.g., on Iso-pucks, would bring notably superior results. Or is more a matter of visual, as opposed to audible, aesthetics?
