If we're going to be serious now, the best speakers that _I've_ experienced - meaning the speakers that gave me the more intense, emotional connection to (reproduced) music I've heard - were the Cogent field-coil horns. Driven by Welborne electronics in the Welborne room, RMAF 06. They gelled perfectly even in that small room, and the lack of low bass was entirely a non-issue.
Sounded good the next year, too, with much more expensive/extravagant electronics, but, for whatever reason, did not create the same magic (for me).
I think second for me are the very pricey near top-line Audio Note AN/Es.
Luckily for me the much lower-priced AN/Es are also pretty damn good. Amazing, actually.
