Musicbook 20 / 25

The musicbook DSD is a versatile signal source which, in addition to digital and analogue inputs, also offers a USB audio input and a Bluetooth receiver. Depending on the model, the musicbook DSD can also be fitted with a network player and a CD drive. Music playback in the DSD format is possible over the network player and via the USB interface. As a matter of principle, DSD data are processed on a native level in the Musicbook DSD, hence without converting them into PCM. Only that way this format can unfold its true potential. More over the musicbook DSD can convert ALL digital input signals into DSD using a re-sampling process and convert them into analog as DSD signal. Alternatively the options of Native reproduction (without processing) and re-sampling into PCMx2x4x8 (352.8 kHz or 384 kHz, also called DXD) are available. The musicbook DSD is an entirely new device, USB interface, Bluetooth interface, D/A converter, analogue preamp and headphone amplifier were completely redesigned in the course of the past year. That said, the musicbook DSD easily out¬ performs its predecessor models - in terms of features AND sound!
