the less class of operation matters. Class A is used to linearize the output section, handy when there's little or no feedback. These days with more advanced semiconducters available, there's far less need to do that.
Of course it matters how well the feedback is applied. If done incorrectly the feedback may well cause more problems than it solves (such as harshness).
This applies even if the amp is class D. IOW there are class D amps now that rival the best of class A amps.
So you just have to play them and see what works for you.
