FWIW, I just came across this
recent review of PMC IB2i by Aron Garrecht on Ultra Audio. Some conclusions:
"What the IB2i made clear is that, as always, sound is paramount, and when it came to sound, PMCs IB2i is a beguilingly good-sounding speaker that I found difficult to stop listening to.... The integration of the drivers outputs was so good that they reminded me of the point-source coaxial drivers used in such speakers as KEFs Blade. The quality of bass on tap from PMCs ATL technology and robust carbon-fiber piston driver working as one is also equal to or better than that of most floorstanding bass-reflex designs Ive heard in this price range. But the real jewel of the IB2i is its exquisite dome midrange driver -- it provided the most neutral, natural, lifelike midrange Ive heard in a speaker south of $40,000."
He, too, questions their price but finds it justified by the sound quality. Having lived with these speakers for a couple of years, I find his analysis right on. YMMV.
