Cambridge Audio's entry-level DacMagic 100 delivers an astonishing performance for the price. It offers a 2.3V maximum output, a wide 109dB A-wtd S/N ratio (via both S/PDIF and USB), a low 46ohm output impedance and very low 0.0005% distortion at peak output through bass and midrange. Distortion does increase slightly to <0.002% at 20kHz but this is consistent up to 192kHz input sample rates (the DacMagic 100 fails to lock to 176.4kHz, however). The S/PDIF and USB responses are otherwise entirely consistent, flat to within ±0.02dB from 20Hz-20kHz with 48kHz sources but subject to Cambridge's proprietary filtering with 96kHz and 192kHz sources (there's a gentle roll-off of -3dB/31kHz and -24dB/40kHz).
