The Sierra’s are great, but won’t image as well as the BMR.
The S400 is good, but not as good as the Sierra’s nor BMR, srill bests most other speakers around its price.
For the Silverline, Stereophile measured a much cheaper speaker than that one a while ago and it was decent, it the Grande crosses a 1” tweeter at 3kHz with a 5.25” driver, which slightly alarms me.
For the De Capo Be, I’d stay away. One reason they measure so poorly is because of the slope of the cabinet, which was done out of stupidity. That should never be done unless meant to be used on a desk. They do that to time/phase align the drivers, but that can also be done in the crossover and/or by physically having the tweeter sunken in (my speakers do this).
