Could any of you guitar virtuosos out there please explain to me in extreme laymen's terms the purposes/advantages of utilizing a power amplifier (rack-mounted or otherwise)? I would greatly appreciate it!

The power amp basically boosts your preamp signal to audible levels. For example you could use something like a Line 6 Pod XT Live into a speaker cab but you'd have to stick a power amp between the cab and the Pod.
