Selling our store demos of the Lindemann Musicbook DSD 25 (upgraded) Network Audio Music Player and MusicBook 55 power amplifier. We are selling these together as a set. Asking $5,900 for the both.. MSRP is $9,800 for both.
MusicBook: 25 DSD 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.

MusicBook 55: The musicbook: 55 is our offer for music lovers who value excellent sound, but also enjoy whooping it up at times. Punchy, well-contoured lows, most delicately sculptured highs and an extremely natural and homogeneous vocal reproduction are the strong points of this new power amplifier.
The musicbook: 55 is a class D stereo power amplifier based on a multi-patented circuit design, the UCD amplifier. Owing to a circuit layout that’s been reduced to the essentials, a discrete circuit design and careful fine-tuning the musicbook: 55 achieves a sound quality that makes a lot of big bolides look pretty much outdated. A sound, so rich in detail, natural and particularly dynamic! Just lend your ear and you’ll be surprised at how good class D can sound these days.
