I don't have any links at the moment but I can tell you a lot of the "phat" voicings come from extensions(9ths, 11ths, 13ths) and alterations(#5ths, b13ths, etc.).
One good source I've used is Jamal Hartwell's videos. Here's his channel
https://www.youtube.com/user/GospelMusicians. I've bought one of his dvds as well which helped me quite a bit.
Also Mike Bereal and Jason White's dvds and videos helped. Along with the other videos from Hear and Play Music. I bought one from both Bereal and White they catapulted my playing to a much higher level. However the chords they show are rootless so if you don't have a bass player you'll have to modify them. This is their channel
