I just received a pair of the B6 10x50 today. My first impression was a little underwhelming because the CA was noticeable. But, I was specifically looking for CA, viewing difficult targets (overhead wires and black railings against a clear December sky at midday) in direct comparison with my Victory SF 10x32 (which show effectively no CA). When I came back to them later in the day and wasn't trying to find CA, it was only barely noticeable when looking at difficult targets.
In terms of sharpness and resolution, I'd say they're equal to the SF 10x32, at least for my eyes, which probably aren't the sharpest. FOV is noticeably smaller than the SF 10x32, of course. To me, objects looked bigger in the B6 10X50, but I'm sure that's just an optical illusion due to the narrower FOV. They do seem a little brighter than the SF 10x32 even in full light, and definitely have a slight edge in performance at low light over both my SF 10x32 and NL Pure 12x42. I couldn't compare them directly to my SF 10x42 as they're with Zeiss to have debris cleaned out of the barrels (they're one of the early grey models from the era when Zeiss didn't seem to be able to make an alpha binocular without leaving a bit of grit in it for posterity), but in previous head-to-head comparisons, I haven't seen much of a difference between those and the SF 10x32 or NL Pure 12x42, so I would still expect the B6 10x50 to outperform them in low light.
I also got the Maven doubler to go with the B6, and find it to give a useful view. Not a beautiful, wide, scintillating view, but one which is sharp and definitely provides for more resolution of fine detail. The function of the doubler is just to give you that extra bit of resolution when viewing a stationary or slow-moving target from a tripod, not as the primary optic for scanning or immersive viewing.
So will the B6 10x50 displace my favorite binoculars for general viewing? No - that's still my SF 10x32 for general outdoor use, and the NL Pure 12x42 for when I want the ultimate hand-held image, even at the cost of a bit more weight and bulk (with the forehead rest included). The B6 10x50 are light and compact enough to substitute a good 10x42 for general use. But despite offering a very pleasurable viewing experience, the OK-but-not-outstanding FOV, and the occasional glimpse of CA, will always remind me they are not the very best.
I do still think the B6 have a place in my collection - for times when I want the best low-light performance in a hand-held binocular, and for times when I want a lightweight set up that can do it all (general daytime observation, low-light and basic astronomy, and tripod-mounted long-range observation with the doubler) - i.e. when I don't want the size and weight of carrying a proper scope alongside binoculars, or don't want to carry multiple $1000s worth of equipment on me.
I can also imagine them being a good choice for someone looking for a similar, very versatile set-up as a one-stop solution for diverse observation needs, particularly if they don't have money to burn or a weird optics fetish.
