iFi introduces xDSD “next generation” mobile audio

iFi, the Southport, UK-based sister brand of Abbingdon Music Research, has introduced the iFi xDSD.

Its hi-res DAC system supports PCM and DXD audio data up to 32-bit/768kHz and DSD up to 22.57MHz (DSD512). A customised ‘True Native’ Burr-Brown DAC chip handles PCM and DSD natively. The music signal stays in its original format throughout to maintain purity.

The unit offers universal wireless connectivity via Bluetooth, support for the sonically superior aptX and AAC codecs enabling enhanced-quality streaming from both Android and Apple devices, and the xDSD remembers up to eight devices once paired.

iFi’s proprietary ‘3D+ Matrix’ and ‘XBass+’ circuits may be switched in or out as preferred, enabling a degree of personal ‘tuning’ to suit headphones and music genres.

A new ‘Cyberdrive’ headphone amp stage combines the sonic purity of analogue circuitry with the convenience and precision of digital control. Proprietary low-noise op-amps and dual-mono headphone drivers supply sufficient power to drive high-impedance headphones, whilst also delivering ultra-low-noise performance with high-sensitivity headphones (including premium in-ear monitor.)

Asynchronous USB input is provided by a Type A interface, with ease of connection to multiple devices (Android via USB OTG; iOS via Apple CCK). Coaxial and optical S/PDIF connections are enabled via a combined 3.5mm/mini-TOSLINK input (a full-size TOSLINK adapter is also supplied). The xDSD’s output can be switched between headphone and line-level mode, the latter delivering a fixed 2V output that bypasses the volume control, 3D+ Matrix and X-Bass+ circuits for integration into a home audio system (the last-used settings are retained at switch-on).

The xDSD is the first product in iFi’s new ‘x series’, featuring a ridged housing made from strong lightweight magnesium-aluminium alloy, ion-plated with a dark titanium finish. The radio-frequency-transparent endcap permits extended Bluetooth range.
