[...]The problem with omnidirectional speakers is that low level details are completely lost due to masking effects.

What is usually meant by masking is that a loud tone at F will inhibit perception of a less loud tone at F +/- D. The smaller the D, the smaller the difference in loudness needs to be for the least loud tone to be surpressed. This cannot play a role here.

The other masking effect I know usually goes under the name of precedence effect. The first wavefront will inhibit perception of the same wavefront delayed by reflections or path length differences. This obviously does play an important role here, but it points in a different direction than you suggest. Because reflections are surpressed, what is perceived is only the initial sound source, whether it be from omni or controlled directivity loudspeakers.

As a matter of fact, I think it works the other way around, and the way Geddes for example feels a need to heavily dampen the space behind the speakers provides anacdotal evidency for this. Controlled directivity speakers in general have very sloppy and eratic frequency response outside the listening window. In other words, the sound that emanates from the sides and rear of a controlled directivity loudspeaker can be substantially different from what comes out of the front. Sufficiently different for the reflections not to be suppressed by the Haas effect, which as a result makes them audible. [...]

[...] I've placed the speaker pair in a number of locations in my living room. Imaging detail and stability is fantastic.

Even when placed directly in front of brick wall. Of course EQ changes, but this doesn't impact imaging and spaciousness. The walls presence is completely imperceptible. From as far back as I can get to just short of placing head in between the speakers the image remains stable. Approaching the speakers is very much like approaching a live stage.

if you take a look at what's really going on in recordings, playback rooms are generally small and the early reflections happen very quickly-whereas in a recording space (or simulation of a recording space that we do with artificial reverb), those reflections are much, much later in time.

What happens is that the early reflections of the playback room carry information about the recording room quite well.

I've been enjoying 3 flooders played through the matrix, and even the crappiest recordings got immediatelly improved and became almost pleasurable.
