I personally know one dealer who's recently shuttered their doors, but is still listed in the active dealers list I believe, so the numbers may be even worse than 22. B&O has never had the market penetration in the US they do in Europe or the UK. The whole concept of solely B&O stores vs. selling at other stores as well is one where there's not a good answer I think, a lot depends on the store. For example, when I lived in Florida there was a highish end place that sold B&O as well as McIntosh, Pioneer Kuro, and a number of other high end brands, and their specialty was custom installs and theater rooms. Located in the wealthier part of town. They did a very good job selling B&O and demoing it well.
Eventually they dropped it when B&O went with selling thru a Florida electronics chain called Sound Advice, now defunct. I may have had a hand in accelerating their move to single brand stores...when I was buying my BS9000/BL8000 combo, I contacted B&O often about how poorly Sound Advice was doing with their products. First, they kept them out on the floor in a wall display, next to the boom boxes and TVs. It was so noisy out there you couldn't tell what anything sounded like, and every snot nosed kid or idiot adult who wandered by kept pawing the gear, so it was all covered in fingerprints and smears, and a lot of it didn't work, glass doors hanging askew or jammed, etc. A horrible way to try and sell such a product. I kept complaining about how badly the experience was and how poorly they worked to get me what I wanted, and the rep wound up giving me a fair number of B&O swag items to try and pacify me, which is how I got my bottle opener, tape measure, and complete set of the BS9000 custom CDs.
And from what I've seen with the dealers I have known B&O doesn't exactly treat their dealers that well. We've discussed the mandatory expenses for Play displays and such and then discounting the product thru mail order or other retail outlets, etc. I personally would not want to be a dealer now, as much as I love the brand.
