Find your own religion - don't buy into someone else's beliefs. All the various amplifier topologies have their merits as well as their weak points. There is NO one easy solution, no one right answer. Listen to all kinds of systems and figure out which one connects to your idea of what a live even should sound like (if that is your criteria for what a good system should do to make you happy and engaged with the music). I agree that the interface between amp and speakers is critical, especially when considering SET amplification where potentials are more limited, or electrostatic speakers that require gobs of current to sound their best. Enjoy the ride!
Merry Christmas!
