Icon HDP

Listening to the Deep Sea


  • Hi-Res audio compatible
  • Fully differential digital-to-analog conversion circuit built on 24/192k DAC chips
  • Precision machined aluminium chassis
  • Pure Class A headphone amplifier, capable of driving true audiophile headphones
  • Connects with all digital and analog sources— TV, CD-player, PC/Mac and more




The Nuforce Icon HDP incorporates a full-speed USB DAC (24bit/96kHz) and full-function S/PDIF D/A converter (24bit/192kHz), plus a headphone-amplifier circuit and preamp output. Supporting Digital USB, S/PDIF in coaxial and 3.5mm optical (3.5mm) modes, along with an analog line input, the HDP accommodates all manner of audio devices. The Icon HDP, which has been designed to serve as the heart of a high-performance audio system, competes head-on with DACs and preamps costing several times its price. Nuforce USB Audio devices are designed to work with x86 architecture. Tablet devices running Windows 8 (RT) are not supported.
