This post comes late to the party, but I have heard most of these speakers and thought I would weigh in. Cut to chase, I bought the Apex after long listening and decision making process. They sound similar to the MA silver series, but you can hang them on the wall.
I bought these speakers online sight unseen without hearing first, but based purchase on listening to Paradigms described above, B&W m1's, MA silver RX1, RX6, and Radius HD series, and various other brands like Vienna Acoustics and Definitive Technology.
I listened to the Paradigms with a NAD T777 receiver and they really didn't stand up well against the new B&W m1 satellites, at least in that room, compressing at higher volume. The B&W m1 sounded good, nice highs, but the bass was lacking without sub support, and I was concerned about the high crossover point for music.
I really liked the MA stand mount and floor standing speakers, and a trial of the bigger radius models was also impressive. Based on that I ordered the Apex and they are terrific, both the A40 and the A10 which I have both tried as fronts. Their dynamic envelope is much greater than my ears can handle, and the A40s perform like small floorstanders, with a 2.5 way crossover. Voices and horns are gorgeous, and drums and other loud sounds (like explosions) are convincing.
Tough to find these speakers in brick and mortar stores to demo, at least here in US.
