If you want to keep with something like your Triangle monitors, I recommend you take a look at the Revival Audio Atalante 3 monitors. They also have a new line out (just recently) so maybe the Sprint 4 as well. They're a relatively new company founded in 2021 and like your Triangle speakers, they are designed and built in France. I have the Atalante 3 monitors and am hopelessly in love with them.
All the best,
