I would suggest some background reading.
I would seek out the chapter on amplification in Robert Harley's "The Complete Guide to High End Audio" for a general and relatively easy-to-understand discussion on amplification and some of the differences between solid state and tube amplification. I'd also read the section on speakers (because amplification is simply driving a load).
Then, I would go to the Atma-sphere website and go to the "Papers" section to read the paper titled Debunking Common Power Amplifier Myths and the other titled Competing Paradigms in Amplifier and Loudspeaker Design, Test and Measurement.
Knowing how tube amps create their "power" and how transistor amps create theirs, and understanding how speakers present a load to each particular kind of "power" will make things easier to get through the Atma-sphere papers though they may be able to be tackled on their own.
