With 50 years in this hobby, I can say that if it doesn't wow me right out of the box, there is no amount of break in or fairy dust that will make it sound much better. No speaker should need 200 hours of break in to sound decent, especially a pair that cost 19K. If the speakers do indeed need that much break in time which is quite doubtful, why doesn't the factory do it before shipping?
If you can only listen to half your music collection, then something is drastically wrong. No way would I drop 19K on speakers, only to be able to listen to half my music collection. I had an audiophile friend years ago who proudly told me that his system was so good that nothing sounded good on it because it showed all the flaws. To that I say BS. I would look for a preamp or integrated with tone controls to tame the speakers if you are dead set on keeping them. If it were me, I would unload them very quickly and move on to something I could actually enjoy.
