I have not tried them, but if you are new to isolation tweaks I suggest you experiment with the low cost Vibrapods. Try several different versions of them under different components and note the changes. Once you are comfortable that there are indeed changes in the sound, move up to more expensive cones and/or bearing devices one component at a time. There are generally many such items for sale used right here and the forum archives have many DIY projects as well. Isolation tweaks can be a very cost effective method to improve even a modest system.
