iFi Unveils Battery-Powered Amp/DAC for Hi-Res On the Go

UK-based desktop audio specialist iFi audio has introduced a battery-powered ultra-portable amp/DAC (digital-to-analog converter) that makes hi-res audio transportable.

The xDSD ($399) is built around a Burr-Brown Hi-Res True Native DSD DAC chipset and certified as a Hi-Res Audio device by the Japan Electronics and Information Technology Industries Association (JEITA) and Japan Audio Society (JAS). It supports MQA (Master Quality Authenticated) files, PCM up to 32/384 kHz, aptX-enabled Bluetooth streaming, and DSD up to 256 times the sample rate of a CD; PCM768kHz and DSD512 are also supported via a free firmware upgrade.

Encased in rugged magnesium-aluminum chassis, the xDSD is equipped with USB and S/PDIF inputs as well as a 3.5mm balanced TRRS headphone output and fixed 2-volt line-out for connection to an audio system or active speakers. Its amplifier is rated to deliver 500mW per channel — “enough to drive all but the most power-hungry headphones” — and listeners can choose how much power to apply via a feature called IEMatch (for in-ear monitor).

iFi says up to 8 hours of play time is possible when the xDSD’s internal 2200mAh lithium-polymer battery is fully charged.

Other features include XBass and 3D+ Matrix listening modes, the latter of which is said to “restore the correct sense of placement that the artist is in the room and outside your head.”
