It’s like the law of infinite halves. You can never reach it.

I’ve heard few 2.5 way speakers that sound good. A Sonus Faber and a Dynaudio, that’s it.

2-way is often simpler to make work well. One crossover point, smaller cabinet, etc… typically the first question is the room size and needs of the amplification. If you’re in a medium to small space then almost always a 2-way of equivalent price with be superior. I think this remains true up into a few thousand dollars a pair if your room size is smaller. Typically higher priced two ways also have better mid-bass drivers that can play lower as well. My personal opinion is that your room needs to be quite large as does your budget for a 3-way system to serve a better outcome. Some will disagree though. I still rock high end two ways. Dynaudio Special 40s and I feel there’s few compromises.

Yes. Mainly because I have young kids and don’t get to listen to the High End system often, so I usually don’t pick mediocre recording that I just like. I save those for the car.
