There are two main reasons I love B&O. In the first place, no other audio/video manufacturer has as much devotion to modern, artistic design as B&O. The world is filled with boring, ugly boxes, both for electronics and speakers, and I got tired of trying to hide them in order to have the design I wanted in my home. No other firm has as many items in MoMA as B&O. The quality of the materials and finishes are first rate. The quality of the electronics, well, sometimes hit and miss depending on the product. And recently, unfortunately, I think their styling has gone downhill, I can't think of any of the new speakers that I like the looks of better than the ones they replace except the Beolab 18 which is a wash compared with the BL8000. I don't like the look of the Avant as much as the BV11, the Moment is ugly in my opinion, etc.
The second reason is that there are very few manufacturers of loudspeakers who have as good an understanding of acoustics, and lately DSP, as B&O. Far back in the 70s they were doing things relating to phase response and power response that most manufacturers didn't begin to address for decades. There have also been few manufacturers who have embraced active speakers over the years, and no one to the extent of B&O, with all the advantages that active loudspeakers provide.
