sakabatou Posted May 11, 2020 Share Posted May 11, 2020 Actually you can use 12-19V, as long as it can produce enough current - unsurprisingly, Nucleus follows Intel NUC specs https://community.roonlabs.com/t/best-linear-power-supply-for-nucleus-now/43495/33 2 Link to comment Share on other sites More sharing options...
RussB Posted May 11, 2020 Share Posted May 11, 2020 Both SOTM SPS-500 and SPS-1000 have produced significant improvement in sound quality over the standard supply in powering my NUC 19v. Suggest adding these to your list. 1 Link to comment Share on other sites More sharing options...

RussB Posted May 12, 2020 Share Posted May 12, 2020 They do produce a different sound in my system, which is not unexpected given their different construction- the 500 is a high quality switching mode supply and the 1000 is straight linear. Unfortunately I haven’t been able to isolate the difference in powering the NUC as whichever one is not on the NUC has to go on my streamer! (SOTM’s SMS-200 Ultra). Based on other comparisons though, the 500 seems a bit more dynamic but has a little more of a digital edge than the 1000. I bought the 500 on SNA and the 1000 from Crux Audio in Australia. 1 Link to comment Share on other sites More sharing options...
