From my experience, you have to decide what type music you listen to, i.e. hard rock, metal, punk, grunge, jazz, blues, opera etc.
Hard pumping rock requires a certain speaker and equipment to push out those thumping sound waves, all speakers will play any type music, but that heavy low bass and higher bass sound waves, that bounces off your chest with authority is special.
Certain audio systems and speaker combos will reproduce solo voice (Adele, Aurora} or solo instrument (pink floyd, pearl jam, or even Yuja-Ravel piano concerto) great.
However don't do as good of a job with separation of sounds on the stage in front of you, offered by a plethora of dense sounds coming from hardcore punk, or even large symphonic orchestral music, at least in a 3D since, left to right, and front to back.
I personally dont listen to crossover trash rock or hardcore punk type music and only a few metal bands, I stick mostly with, classic or progressive rock, alternative rock, some electronic music, some pop, and classical genres.
I needed a speaker that would do all genres very well to great, and avoided the chest vibrating, neighbor hating sound waves (as much as I love it when at friends houses)
I ended up in the price range you want $30K-$40K, I gave up on my Thiel CS5 speakers and went with German Physiks Carbon mkIV, fairly small form factor, smaller than the thiel cs5's, i haven't found a need to upgrade since. German Physiks offers a larger speaker, that doubles the amount of speaker sound, I never found the carbon mkIV to be lacking in sound projection, and gives me a 3D sound landscape coupled in synergy with the rest of my equipment
Good luck with your search
