Watch the Smooth Voice online guitar lesson by Brad Carlton from Chord Studies: i to V7 Vamps Vol. 1
Here's an example of some great voice leading where you don't have to move very much at all to accommodate the chord changes. We start with the Am9 in tenth position. If you just move up one fret raise the C♯ to a D you have your E7♯5. As you can see, this is very smooth voice leading.
