WEBMay 5, 2010 · Pros: Versatile, Small Size, Acceptable Performance. Cons: Amplifier is not powerful enough, Poor design, DAC sound is treble accentuated. I owned the Nuforce HDP for two months, I tried it with several headphones ranging from the 600 Ohms DT880 to the 300 Ohms Senn HD600 and HD650 and 62 Ohms AKG K702.
