I suggest you buy cones/spikes and Vibrapods (or a similar decoupling device...perhaps one of Herbie's products) that can be auditioned in your system with a 30 day home trial, and listen for yourself.
There are many devices that can be purchased with 30 day return policies (AudioPoints, Herbie's products, SR Research MiG footers among them).
