If you are so worried about it, you could try adding a MOV to limit inrush current and experiment.
To repeat these are mostly cosmetic issues and not a source of significant failures. If they were the SKUs with poor turn-on/off behavior would be rejected by the marketplace already.
For TMI back last century at Peavey I (we) used a popular op amp in many output circuits because of its benign on/off behavior, it was not the best bang for the buck op amp for noise and slew rate, but did not "bang" during turn on/off and scare customers away.
I would caution against looking for easy answers. In some cases the circuit behavior is strongly influenced by how the power rails come up initially. One engineer working for me even went so far as to design in a PS sequencing circuit that would not allow one rail to come up, until the other one was already up ( I don't recall which one had to be first, but it mattered). In power amplifier design a great deal of design effort goes into managing turn on/off pops, clicks, bangs, and wheezes. Another common cosmetic fault is a power amp that goes through a momentary period of instability as the rails decay between valid on and off states. I recall in some early class D designs that special attention had to be paid on making sure the output drive didn't get stupid, before the PS collapsed to harmless levels to avoid self destruction.
It can help to put all of the line level gear, feeding a power amp on its own power strip, so you can turn it on first, and off last, especially if using exotic gear designs that don't pay attention to such cosmetic issues. Back last century I even considered a dedicated power strip that would delay and sequence power, but the market was far too small, and price sensitive for a Peavey product. I expect there are expensive solutions that do just that.
