A typical customer voice:

“..I have to admit that the Analog Power Box is a significant step up over the DLCP version. The sharpness and nervousness of the sound disappeared. There is much more culture in music.  Also, there are better low registers, better details across mids, spaciousness, and air without harshness. All in all, it is so much more pleasure to listen to.

Improvements make it worth spending!
Thanks, Marcin”
