I own a set of LSA 20 Statements, for about a year now. They replaced a much smaller set of Monitor Audio RS 6's, which were great speakers, but in my medium-large room they were a little lacking on low end. The LSAs have more low end, sure, but not that much. In fact that's my biggest complaint, they don't exactly lack bass but they don't have as much as I feel a speaker of that size should.
Imaging-wise they do well, and to my ears they sound relaxed and neutral. I was worried they might sound a bit harsh with my (all solid-state) gear but they don't.
Mine arrived in perfect condition, and I don't have any experience or knowledge of poor cabinet quality, but I suspect they're relatively cheaply made as others have said. Which is concerning because my LEAST favorite thing about them is the too-narrow 3-point cone base. It feels to me like if anything bumps into one it will fall over easily, and then I'll get some first-hand knowledge of the cabinet construction. These speakers need a better base.
So I guess my opinion is pretty neutral. I think these are a decent value for the price (the real price - nobody should pay the "list" price of $6k for these things), but you get what you pay for, like everything. When I bought them, they fit my budget, and that was the deciding factor. If I had to do it over again, I may look elsewhere, but I'd likely end up spending twice as much for a marginal improvement in sound.
