The term distortion is entirely foreign to the NuForce icon HDP (450 euros), only microscopic traces of it can be found.

The name HDP stands for “DAC, headphone amp, preamplifier” and describes it quite well what can do the small NuForce. What you didn’t see the box, but only step by step need to be explored in laboratory and listening room sessions is the quality with which it handles its manifold tasks. Rarely, the tester in the face of a 450-euro device has so amazed.
The HDP via coaxial, USB or fiber optic will contact with digital feeding devices. The latter entrance is a combined optical-electric mini jack and also serves as a second analog input. There are a total of five inputs, solid snap-switch offers but only three positions: “U” for USB, “D” for digital, “A”, for analog. A signal is present at both digital inputs, the optical has priority automatically.
Why this is so, remains the mystery of NuForce developer. It is only a secret of many. Also the chips installed in the HDP remain anonymous, all beetles have their own “NU”-type numbers. The suspicion in this way cheap material should be discreetly hidden, could be no more far-fetched – already in the laboratory, he is definitively refuted: 113 dB keeps a distance of the DAC to the noise, the analog input are also very good 102dB.
With three output voltage and 100 ohms output impedance output stage limits no facilities projects of the user, and also the headphone amplifier (a class running A chip that will sound warm) is low impedance and powerful enough for top models. Where the NuForce sounds then also very fine one. On the reference system (and especially directly on the amplifier) sounded the all-rounder revamped brighter and slightly slimmer than the three times as expensive ‘major’ DACs in this test, amazed but also with a very suggestive representation of space – a crazy little thing with cult potential.
