The best I've heard are also the ones I now own and have reviewed right here on A'gon: Intuitive Design Summit PSL 624 loudspeakers. (PSL = Pitcher Sound Labs). Astonishing imaging, in a wonderful way, and that's with a behemoth "entertainment" center positioned right between the two speakers. It's as if the entertainment center didn't even exist. They have it all, and in spades: Height, Width, Depth, AND a wiiiiiiide sweet spot. Phenomenal off axis dispersion with no discernible loss in precision of the imaging. I'm awestruck, but as you can see, not dumbstruck. :)))
Sooner or later, people will start to figure out how great these are, assuming they get a chance to listen to them.
Nope, I don't sell them. It's just wonderful to finally be satisfied with my speakers, and not have had to mortgage the house (again) to get to that point.
