  • Aurender Flow D/A Headphone Amplifier
    Aurender Flow D/A headphone amplifier 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. Internally, the Flow is powered by a 3.8V, 4450mAh Li-ion rechargeable battery claimed to provide more than seven hours of playing time. The USB interface chip is an XMOS XS1-U8A-64-FB96, while the DAC chip is the popular ESS9018K2M, which supports PCM playback at resolutions up to 32 bits and 384kHz, as well as DSD64 and DSD128. Five pushbuttons along the Flow's right edge allow power on/off, access to the setup menu (one press for the most frequently used functions, a long press for other functions), and three transport functions.
