Headphone Reviews

The golden rays pouring in through the left oculus transport a tiny child carrying a cross: ". . . the devil was vanquished, as if he had just swallowed the bait in the mousetrap." In his essay "'Muscipula Diaboli,' The Symbolism of the Mérode Altarpiece," the late art historian Meyer Schapiro explains how every object, every surface—even the smoke, light, and volume of space—depicted in the famous triptych by Robert Campin (ca 1375–1444) is a coded symbol explicating the mystical underpinnings of Netherlandish Protestantism.

Aurender was a name new to me when I encountered the company at the 2015 Consumer Electronics Show, where they displayed a range of music servers designed in California and manufactured in South Korea. But what caught my attention in Aurender's suite was their Flow portable D/A headphone amplifier ($1295). This handsome, battery-powered device, housed in a machined aluminum case about twice the size of a pack of playing cards, offers optical S/PDIF and USB 2.0/3.0 input ports and a single ¼" stereo headphone jack. Two features distinguish the Flow from the pack: Its USB input can be used with iOS (iPhone/iPad) and Android smartphone sources, and it can accept an mSATA drive (not included in price) of up to 1TB capacity for internal storage of audio files. Visually, the Flow's distinguishing feature is its round LCD display, which stands proud of the faceplate; the bezel encircling the display acts as a velocity-sensitive volume control operating in 0.5dB steps.
