KEF’s 50th Anniversary LS50

Not only was Stereophile celebrating its first half-century at RMAF, so was British speaker manufacturer KEF with the US premier of its LS50 ($1499/pair) in one of retailer Hear No Evils’s rooms. Driven by Parasound electronics—ZDAC, P7 preamp, A21 power amp—the sound was both delicate yet full-bodied. This came as no surprise as reviewing this little beauty, whose single Uni-Q drive-unit was developed from that used in KEF’s flagship Blade model, for our forthcoming December issue was a highlight of my 2012 auditioning.
