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?
