I was reading a review of their Lindemann’s Music Player and I saw this:
In terms of technology the musicbook:10 DSD is definitely way ahead of the competition. Using a sophisticated recalculation all digital audio signals are converted into DSD 128/256, a data format which is highly esteemed by audiophiles worldwide. Thus the actual digital-analog conversion is reduced to a mere filtering of the DSD signal. This completely new approach is the secret behind the musicbook’s exceptionally good sound.
I wonder where this idea was born?
