Designed and made by that incredibly clever guy Jan Didden (as seen on diyaudio.com) these could possibly be the quietest switching psu ever made for audio.
Switch mode psu's have a bad reputation for audio but could that be all coming to an end ? A very small unit can replace a large traditional psu made up of transformer, rectifier and smoothing caps. Output voltage can be +/- 15V, +/- 12, +5V and current at 15V is 150mA max and at 5V is 500mA (0.5A).
I find it very interesting as the real estate taken up by the traditional transformer route is moosive and the noise output of these are supposedly lower than linear psu (no 50Hz buzz and harmonics of). Any one who has built their own stuff will be aware of the problems that large transformers and the rectification process can bring.
These SMPSU could have uses in phono stage, DAC, active crossovers, active preamps. No good for power amps though
Might get one just to see what its all about.
