There are a couple approaches. Full blown high end audio racks with built in vibration control ($$$$$) and high quality sturdy racks to which you can add vibration control. When I have researched the topic before I always have come to the conclusion that the most cost effective route is great sturdy racks with enough space to add various vibration control devices under each component.
This allows approaching each component separately and spreads outlays over time. So, in my case I have an excellent Silent Running Audio custom Ohio Class vibration platform specifically designed for my turntable. While under the rest of my components I have combinations of Black Diamond Racing platforms, pucks, and springs. So, this approach really allows a lot of flexibility.
Top notch audio racks with sophisticated vibration control cost a lot.
