qualité pas au niveau de ce qu'on attend d'Audiophonics
reperage et qualité des fils de sorties laissant à désirer. Pour cabler en parallele les 2 sorties, il faut faire plusieurs tests et plusieurs mesures. Hum present apres mise en parallele des sorties, donc qualité et symetrie du bobinage pas tres bonne.

Make a change!
If you working on electronics about 35 years (like me for example) you have a lot of chances to see new things!
One of these things was that, to replace my toroid transformer in my 20 years preamplifier (Diy Hi-End) with R-CORE.
The reasons was two!
First, when i put my ears very close to toroidal trafo, i was hear hum noise!
In the past i never checked to hear that, and second reason after a lot of reviews all around the audio forums, i was thinking that, it is not a bad idea with this little cost to make a change!
Everything for experiments! That's the life!
About results?
The most important there is no hum noise, second i am not sure but i believe something has change to the better way!

good choice
bought this transformer together with the linear power supply 12220 from this shop for an audio streamer made with a raspberry pi 3 and hifiberry dac pro .
it is working perfect for me,no humming or other disturbing noise and enough power to work with raspi,dac and the 7 inch official display.
even that i do not have "golden ears" i was able to hear a difference between this power supply and the Meanwell power supply i used before.
i will buy this transformer again for further projects.
