Robert E. Greene has posted a review of the Sony SS-NA5ES loudspeakers ($6000/pair) at The Absolute Sound. His conclusions:
“The Sonys do not sound exactly like ordinary speakers. But I can promise you that if you grant the design the premise of its balance, you will find them hugely rewarding. With a subwoofer system added—either Sony’s dedicated one or some other that suits the speakers—you would have a full-range system that in a room of ordinary domestic size, is truly extraordinary at any price. To my mind, the word “masterpiece” applies.”
