I agree that many SET amps aren't versatile. Like any other topology, only a few examples excel across genres.
I was late to SET for this reason. In the 90s, all examples were slow and rounded, and crossover-based speakers didn't leverage them well. I tried single driver speakers but they were too colored with shout and glare at the time, most also lacking any reasonable power handling.
I found two breakthroughs in sequence. Audion's 845 mono amps combined real dynamic muscle with SET finesse, and Audion's circuits all sound uniquely "fast." Faster than push-pull amps. The second breakthrough was finding Zu's full range driver speakers, especially the Definition.
101db efficiency from a speaker that can also take a 1000 watts amp is a remarkable thing. Crossoverless coherence, near-electrostatic speed, and the dynamic response to pressure a room on 25w changed the equation.
The combination will play the 1812 Overture, and UB40, as well as Dusty Springfield or a solo piccolo recording. But then Definition is a speaker good to below 20hz if your room supports it, and gets to 101db on the first watt, 1 meter from the speaker. Most people in all of audio have never heard this, and it's not only Zu that can put you in the realm.
Point is, I don't let the gear determine the music I listen to on it and no one else should either. Today's market gives everyone options for more convincing fidelity from simpler gear, more akin to what instruments and voices sound like, but those options aren't generally coming from the best known brands and their design rut.
