Update: the Focals have had their requisite 100 hrs. of break-in now and I do think they've opened up rather nicely. This difference isn't anywhere near as dramatic as what I experienced with the new pair of ProAc Response 1SCs I bought a good few years ago. Now, THAT was a learning experience!
The Focals' stereo imaging is truly excellent and their presentation is musical and involving. No, they don't dig very deeply into the bass but the sound is nicely balanced all the way up the spectrum and my typical listening levels don't extend to floor-shaking low frequencies anyway. Just for fun I tried these out in my main system (Modwright KWI 200 amp, Cambridge Audio CXU, AMR DPP 777 DAC, Rel S-2 sub) and though they were no match for my Ryan R610s, the things these Focals did well they did very well indeed. Don't drive them too hard though, they'll get kind of harsh. But for the way I'm using them, they give me exactly what I want to hear, so I'm sure they'll be sticking around for a good few years.
Once again, thanks to all for your opinions and recommendations.
