      It's time for genuine CD-quality wireless music enjoyment from portable devices. iFi Audio xDSD Bluetooth DAC powered by AptX and AAC is the key to high-quality wireless listening from smartphones and digital audio players. Wired, the USB connection offers the ultimate Hi-Res audio performance for smartphones, laptops and USB enabled DAPs with DSD and PCM.

      Ready to deliver stunning quality music wirelessly from Apple and Android smartphones with streaming platforms on iTunes, Apple Music, Spotify, Tidal and similar services. It is able to convey the very highest quality PCM and MQA formats for downloaded and Tidal streamed music in full studio-quality. With cable connection, the xDSD uses iFi Audio's original S-Balanced amplification stage that delivers pure musical enjoyment to in-ear-monitors or headphones.

      To enable limitless compatibility with smartphones and no extra power draw from the smartphone’s battery, the xDSD uses a Micro-USB power input which avoids draining the source devices battery. Depending on the headphones and the connection used, the playback times of the xDSD can reach up to 10 hours for S/PDIF, 8 hours for Bluetooth and 6 hours for USB.

      Higher realms of portable music.


      iFi Audio xDSD


      Concerted Technologies
      To deliver a truly musical performance every technical aspect must be present and correct. From the Burr-Brown multibit DSD1793 DAC Chipset to deliver a realistic, musical sound to the femto precision GMT Clock and intelligent memory buffer system.

      Perfected for MQA
      Tidal with MQA is defining the future of High-Resolution streaming audio. Ready for MQA out of the box, the xDSD also supports beyond full Hi-Res Audio with 11.289MHz DSD and 384kHz/32Bit PCM. Simply connect to Tidal and check the options to stream MQA ‘like the artist intended’ as the MQA team say.

      The iFi exclusive S-Balanced technology delivers the maximum performance from single-ended and balanced headphones alike. Compared to standard balanced circuitry, noise and distortion are lowered by up to 3-fold (9dB). Even with non-balanced headphones crosstalk and related distortion are reduced by 50%.

      3D+ Matrix
      Most recordings are made for speakers (not headphones). This produces what is technically known as ‘in-head localisation’ as if the music plays inside your head. Which is unnatural and frankly obnoxious. The analogue-signal based 3D+ circuit restores the correct sense of placement that the artist is in the room and outside your head.

      Many otherwise excellent and expensive open back headphones lack low bass. XBass+ restores deep, clean and tight bass and puts the ‘meat’ back into the music, without muddying up the midrange. Now EDM or Drum & Bass really plumb the depths of the bass notes.

      Pure Line Out
      Whether at home or in the car, the Line Out mode means the volume control, 3D+ Matrix and X-Bass+ are bypassed and the output stage is configured specifically for the best line operation, avoiding ‘double-amping’.

      Cyberdrive Amplifier
      The Cyberdrive headphone amplifier stage places all parameters of the fully analogue system under digital control for a ‘best of both worlds’ scenario. The Cyberdrive design incorporates the iFi exclusive OV4627 ultra-low noise FET input Op-Amp and W990VST digitally controlled stepped attenuator to deliver a new level of sound quality.

      Advanced Battery System
      xDSD uses a new 3.8V/2,200mAh Lithium Polymer battery that offers 12% greater actual capacity in the same size package. Depending on the headphones and the connection used, playback times of up to 10 hours for S/PDIF, 8 hours for Bluetooth and 6 hours for USB are achieved.
