New New LV-Regulator: an audio-grade low-voltage regulator that uses a simple RC filter (1 ohm & 10kµF) as a pre-filter before the LDO regulator and holds bypass capacitors for all the electrolytic capacitors and a 4.7µF/400V polypropylene shunting capacitor at the output. Perfect replacing the cheap switcher wallwart that came with your external DAC or Squeezebox Duet or Touch.
