- If moving the amp is not an option, what type of material could I put between the shelf and the component to help with shielding?

On other components. 4 ft is just how far I have it, several friends swear that 6ft or more is better. Tube preamps, and phono amps can be especially microphonic, so if your using one make sure your amp is isolated from them. The whole idea is to lower the possiblity of any feedback between components.

Metal is the best shielding for electromagnetic interferance. Also make sure all your components are grounded correctly.
