Looking for a source of vibration dampening sheets

The reason for asking this question to begin with was because I can feel cabinet vibrations along with the music in my CDP and preamp when I place my hand (palm) on top of the components. I figured dampening sheets would help this. Then, I remembered I had three isolation cones in a spare drawer. Sunday, just for the heck of it I placed them beneath my CDP. Like I said above, before the isolation cones, I could put my hand on the top of my CDP and feel the vibration of the sheet metal with the beat of the music. After I put the cones on the CDP, it was greatly reduced, say, 90%. I'm wondering if the coupling I'm getting from the cones is all I need? Regarding the sound, I can say I never associated my component vibrations with sound, but I knew the vibration in my CDP couldn't be a good thing. After the cones were put beneath my CDP, the vibration is tremendously reduced, but not like a night/day difference. I want to say my system sounds more focussed, but I'm not sure if its because I want it to or because it actually is. Any thoughts?

Hi
A little late I arrive, but dont forget to check ear ted dampening sheet. It comes with an adhesive side and you can cut it and damp whatever you want. I used also to damp some of the capacitors of my amps. You can find this in percyaudio.com

Mijknarf, A very tiny cost further upgrade to your cones would be to add dampening using herbiesaudiolab.com Grungebuster Dot between the top of each cone and the flat component chassis undersurface. For a microscopic price, there will be more clearly audible upgrade.
Also, sometimes, placing Audiopoints APCD2 Coupling Disc to receive the sharp point of the cone increases the sonic benefit due to a proprietary design to sink the vibration energy even though the point is no longer directly contacting the underlying shelf.
If you call the telephone number of Herbie's Audio Lab you can get an entire course in how to dampen everything in sight since there is more to know than what I briefly touched upon.
