I can fully confirm everything that has been written about the power supply in other positive reviews.
The benefits of the power supply for a music computer with Roon Rock (in my case Prime Mini i7, DA converter from La Rosita) are unmistakable. I could not imagine such a good performance. The music plays in front of a darker background, more space, improved sound colours, clearly higher dynamics, more space between the instruments, more details over the entire frequency range, bass more contoured, voices stand more freely in the room. All in all, a top unit. Price and performance are right.
Many thanks to the Audiphonics team, service and purchase were first class. Contrary to the product description, a mains cable was also included. A nice extra service.
