I think that people who buy Class AB amps have speakers that require a bit of power for good sound, so they compromise a bit on distortion for power.
Whereas people who buy low power Class A amps have speakers that are quite efficient with benign impedance. These people are after the best amplifier performance possible, taking advantage of the sonic superiority of Class A in spite of the power consumption and inefficiencies.
So the theoretical limits of Class A are not an issue if the amps are not pushed to their limits. I have low power Class A single ended and push-pull transistor amps and they are paired with efficient speakers that have benign impedance.
It's horses for courses. If you have efficient speakers with benign impedance, power them with a low power Class A amp for best sound. If you have inefficient speakers, power them with a Class AB (or B or D) amp, unless of course you can justify a high power Class A amp that runs very hot, burns a large amount of electricity, weighs hundreds of pounds, and costs a big bundle of money.
