High Performance Headphone Amp, DAC, and Preamp
The NuForce Icon HDP is a very high performance headphone amplifier, DAC, and preamp for integration with your home audio system. It features built-in DACs for its USB and SPDIF digital inputs.
The Nuforce Icon HDP incorporates a full-speed USB DAC and full-function S/PDIF D/A converter, 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's flexibility has been designed to accommodate all manner of audio devices.
Competes with Components Costing Far More
Icon HDP is expected to compete with other DAC and preamp costing up to several times its price. It will serve as the heart of a high performance audio system. Icon HDP uses the same DAC as the high-end NuForce CDP-8 (MSRP $1,450.00) and similar preamp to what's found in the NuForce P-8S (MSRP $1,650.00). And it costs so much less!
Purest Possible Sound Quality
For the purest possible sound quality, the digital input has no capacitors in its signal path, and the analog input utilizes a single DC-decoupling capacitor. Components along the entire signal path are minimized.
The digital circuit occupies a separate daughter board. The 24/96 USB interface outputs a I2S signal to the Icon HDP's high-quality DAC.
The DAC chip consists of four internal 24-bit, 192 kHz 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. |
