"KEF Wireless" is the laconic name of the British loudspeaker's icon entry into cable-free audio. Proprietary algorithms (I've heard this so often, it's almost like a pickup line in a bar) resist noise from nearby appliances and ensure audiophile-ish bandwidth. The "after market" version (lower right) has a 50-watt Class D amp backed up with, I'm told, a great power supply. But you can also buy KEF Wireless built as a "doughnut" into one of KEF's slender, world-beating Reference towers (top left). Also in the works: The new Austin series, with redesigned Uni-Q coaxial driver array (KEF likes putting tweeters amid other drivers) with strengthened tweeter and bigger magnets--"not overly analytical" and "easier to place."
