Horn speakers are making a comeback in hifi circles, but the best "horn" speakers in the world are BeoLab 5.
Have been getting some astonished reactions from hifi-afficionados who have been listening to mine; but what's even nicer are the responses from pros. Was in a store today, to check out the Classé CDP-300 universal player, and mentioned I had BL5s. The salesman responded: "Damn, those are fantastic speakers, unfortunately." He had his Classé source and amp connected to B&W 802, so he had a nice reference.
