Product Features

  • Convenient, compact design – Measures in at less than 6” square and 1.5” tall. The seamless cabinet is made of die-cast aluminum, with a versatile, low-profile design that allows for display either horizontally or vertically.
  • High-resolution audio ready – An onboard digital-to-analog converter (DAC) supports high-resolution sampling rates up to a stunning 192kHz/24-bit. And with 4 inputs (USB, optical, coaxial, and 3.5-mm stereo), it’s easy to connect to most any source.
  • Plug-and-play compatibility for Mac & PC – Hook up to your computer and start enjoying the music on your hard drive. No drivers or software to install. A fully asynchronous USB input delivers exceptional quality at all sample rates and from all file types.
  • Jitter-free, high-performance upsampling engine – Burr-Brown’s high-end sample rate converter (SRC-4392) upsamples all digital sources to 24bit/192Hz. The smart re-clocking system uses a temperature compensated crystal oscillator (TXCO) to eliminate jitter.
  • Best-in-class Burr-Brown DAC – Digital-to-analog conversion is handled by an audiophile-grade PCM1792 chip from Burr-Brown, ensuring clean, distortion-free playback of your digital music.
  • Powered by a top-of-the-line digital amplifier – The highly-efficient TPA3118 Class D amp from Texas Instruments achieves the perfect balance of delicacy and strength. Features up to 1.2 MHz switching frequency.
  • High-quality headphone amplifier for immersive listening – Burr-Brown’s OPA2132 dual op amp chip supports a built-in headphone amplifier. Plug in to the front headphone jack for an optimized, private listening experience.
  • Revolutionary Super Charged Drive System (SCDS) – Similar to the drive system in a hybrid car, the SCDS stores USB power during periods of low signal output in order to deliver greater peak power output. The result is a high speaker-driving capability with low power consumption.
  • Precise hybrid volume control – Use the included wireless remote control to control volume, or opt for more precise control via the component’s mechanical volume knob.
