Don't ever, ever forget "sound quality!" It ain't about amplifiers, it is about our musical intention. A forte recorded still sounds forte even when played back at piano dynamic levels--even through a wall or door. If trumpet is our calling, we learn to control not just the dynamics, but the listener as well. If really good we can control conductors and make violists jump out of their chairs with our power. That is my definition of "finesse." Have fun!
