as an analog engineer I've followed audio electronics design for 20+ yrs, so far nobody’s paying me to design the stuff thoughI've designed PWM DC motor controllers, and programmable current drivers for solenoid valves using mosfets, collecting info and models along the way with audio amps in mind, but most of my work has been with low level signals
now moving from signal conditioning/acquisition to motion control/DSP programming - there's a lot more to control theory, esp for nonlinear systems in the last 10-20 yrs than undergrad EEs ever see – which means I get to learn a lot more; multiple domain modeling, coordinated multi-axis force/motion control, nonlinear stiffness, geometric constraints, sensor noise all combine to make feedback amplifier design look simple in comparison
what I’ve seen so far makes it obvious that low distortion analog electronics design isn’t really where audio can be moved forward, the entire 50+ yr old component audio paradigm should be scrapped with loudspeaker/DSP/nonlinear control and room correction integrated from the ground up, baby steps have been made but DSP horsepower and nonlinear control theory have really moved forward in the last decade
(this doesn't mean I'm going to stop thinking about low distortion analog design anytime soon now, I just think it is a sideshow to real advances in audio reproduction)
