Merci, commandée à l'instant

J'essaierai dans un premier temps avec mon alim IFI ....

IFi will definitely improve .I would not expect big step but it will be very audible. Mainly because Node factory integrated SMPU is very weak. Switching power supplies have the fact that when the load increases beyond a certain range, the noise also increases significantly, so i think that the 1 uV/Hz achieved in 9V IFI on 0,7A will be far from working on 5V under 1A load.
Personally, I use LPSU25 from audiophonics.fr (which is a great value for the price) and all measurements and comparisons graphs that are available on ebay were made with its use.
