I’ve never heard any of the 3 you mentioned but have read good reviews of Fritz. What did you like about the Fritz vs the Special 40s?
Below are links to a couple of reviews I did.
In sum, what I liked was the ease with which the Fritz conveyed music in a disappearing way. They just pushed the music forward, if you will.
They worked with tube amps and also with solid state.
Other details in the reviews.
Special 40’s need a lot of power. I found their presentation both engaging and a bit perplexing. As if I was listening to an interesting speaker but the music was somehow behind those effects. Hard to explain. There is a teardown of them (literally, figuratively) at GR channel.

One more thing about Fritz vs. some of these other companies -- Fritz has no overhead, no marketing, no advertising, no factory, no staff. When you spend on his speakers a very high percent of your $$ goes to the parts and expertise in the speaker. The speakers are very heavy and have really great drivers. Most important, they sound amazing.
In retrospect, I actually prefer the Carbon 7’s now, because I’ve decided the Be tweeter is too bright for me.
I agree with the comment about the Philharmonic BMR. Those would be worth a listen.
