I am not a big fan of the B&W 705 S2. They have poor dynamics and so so highs. The Sopra should be a big upgrade in all areas. The the down side of focal in the US is price, there are a lot of things just as good but cheaper. If you like/want the focal and don’t mind paying an up charge for the name/looks they are one of my favorite stand mounts.
The Revel 226be is worth looking at. It would actually take up less floor space as they are very narrow. They can be had for about 1/2 the price of the Sopra 1 if you shop around. Here is a video demo of the two, of course take YouTube videos with a gain of salt.
