I used to sell hifi gear at a shop where we demoed and a/b compared 5-6 full lines of amps and receivers from 15 w/ch to 120w/ch.
Guess what? The more powerful models in the line the speakers could handle were always preferred with most any good recording at even modest volume.
Move forward many years now and now we have powerful very high quality amps (that are often physically much smaller per watt than in the past) and bigger better quality speakers capable of going loud and dynamic much better than ever as well. That's progress! How much one needs in their room in their case, well of course that all still depends.
