After quick delivery to Germany, I unpacked it and connected it to my Jcat XE Evo USB card with the original cable. Initially, the sound was a bit muddy. After a week of break-in, I noticed better dynamics, more bass, and deeper bass. The soundstage details are good; I'll be reordering an Audiophonics DC cable in the next few days to get even more out of it.
I'm very satisfied with the LPSU 100. Thank you very much and best regards from Berlin.
