impedance matching--could you dumb it down 4 me?


with limited time to research the issue fully (as well as a very limited technical knowledge base to begin with), i'd appreciate it if some basic rules of thumb or forumlae could be explained regarding preamp-power amp matching. a few examples of my confusion: does the power amp input impedance always need to be higher than the output impedance of the preamp? or is there an inverse relationship (low ---> high, or high ---> low)? let the spoonfeeding begin. thanks in advance.

The relationship between impedance matching continues between the amplifier and the speakers as well and it's equally important to putting together a nice sounding system.

This really is a subject that anyone interested in high fidelity sound should make effort to understand before spending money on gear changes. Particularly purchases made without the aid of a dealer or experienced adviser. It's far more important when using vacuum tube products as this type of technology is more prone to having interaction problems with the associated components.
