musicbook 25 DSD Network music player

全新數位流系列,內建吸入式 CD 播放器(TEAC)、802.11n WLAN,內建全平衡前級,THD & noise: <0.001%。 musicbook 25 DSD 為 UPnP/DLNA 網路串流播放器,支援藍牙 aptX,FLAC, APE, AIFF, Apple Lossless, WAV, WMA, AAC, MP3 等格式、網路收音機,可升頻所有格式至 DSD 256。內建 A 類耳擴,APP 控制。

The musicbook:25 DSD is equivalent to the musicbook:10 DSD, but has also an integrated streamer which can be comfortably operated via the musicbook: 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. Moreover, the musicbook:25 DSD contains an integrated CD player which convinces by its exceptional sound quality.

But the musicbook:25 DSD can do a lot more. 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:25 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.
