Yes Taters that would be what I would say, at least based on my experience with the Harbeth sound which I love and have quite a bit of experience with.
As for the desktop, I have no doubt they would be great as nearfield monitors, I think they were designed with that in mind, they just might look odd on a normal sized desk, they are pretty good size.
Kef supplies some nice two piece foam plugs for the rear port which really worked well in my set up, many ported designs don't hold up well when you start messing with the port. Point being you could put them on a desk and back them to a wall and still get good sound from them I would guess. Not ideal, but still likely quite good.
If I had to give their best attribute it would be that hard to find combination of a touch of tone density (warmth) with high resolution. They image like devils too.
