If you wish to use your existing furniture shelves then take a look at the VibraBlock Damper from Machina Dynamica which can be placed on any shelf or horizontal support surface to provide excellent reduction of vibration even if you don't choose special footer support under each individual component or your turntable.
I use these with great results in more than one system, even to augment the benefits of already installed special footers.
As mentioned above by Chayro, there is the personal preference of each set of ears that must be satisfied.
Overall, you probably will be pleasantly surprised that an item from any one of the vendors mentioned in this thread is going to sound significantly better than what you are accustomed to hearing.
