Linnenberg JOHANN SEBASTIAN BACH Owner's Manual page 13

For many music lovers, the playback of vinyl
records is the most important medium in their
music collection. This is supported by the
unmistakable character of the analogue sound,
as well as the fact that the playback quality has
improved considerably in recent times.
The BACH phono stage achieves the perfect
analog sound through the use of a fully
symmetrical circuit that suppresses noise and
leaves the sensitive signal of a phono cartridge
in the symmetrical mode.
