Note: These are 2017-2018 models designed, engineered and manufactured in Germany. The musicbook:20 DSD is identically constructed to the musicbook:10 DSD, but has also an integrated streamer which can be comfortably operated via the musicbook iPad app and offers a lot of great features such as the onboard TIDAL and Qobuz streaming catalogs or native DSD playback.

As a side note, it is also a USB digital-to-analog converter with a superb sound quality, which enables the music reproduction from the computer in studio mastering quality. Resolutions of up to 384 kHz PCM and DSD 256 are easily handled.

The integrated analog preamp, which also doubles as an excellent headphone amp, allows the connection of a phono preamp and thus offers a consummate audiophile quality also with vinyl records.

In terms of technology the musicbook:20 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.
