NuForce Headphone Amp and USB DAC Icon HD








NuForce Icon HD

   "World-class performance from your digital source"
High Performance Headphone Amp and USB DAC

The Nuforce Icon HD incorporates a full-speed USB DAC (24bit/96kHz) and a headphone-amplifier circuit. The Icon HD is designed for users who want the Icon HDP's world-class USB DAC and headphone-amp performance without having a need for the Icon HDP's flexibilities. As the heart of the music enthusiast's desktop system, the NuForce HD operates in harmony with the NuForce Icon Amp as a small yet impactful audio system.

Note: The Icon HD employs the same DAC as our high-end CDP-8 (MSRP $1450.00). The following design features contributed to the stellar performance of the Icon HD:

  • Components along the signal path are minimized.
  • The 24/96 USB interface outputs a I2S signal to a high-quality DAC.
  • The digital circuit occupies a separate daughter board.
  • The DAC chip consists of four internal 24/192kHz DACs that provide a fully differential and balanced output. The differential signal's DC offset operates without a need for decoupling caps.
  • Digital and analog voltages each have separately isolated internal power regulations.
  • USB 2.0 Full Speed compliant and 1.1 supported, 8-96kHz/16-24-bit
  • Audiophile-grade DA converter
