Preos - D

State-of-the-Art MC-phono, an exquisite non-oversampling ladder DAC and classic linelevel inputs - three reference level options in one device: the all new TIDAL Preos-D. It is the successor of the 10 years built classic TIDAL Preos. With its improved legendary state-of-the-art MC-phono part, the unique level control and its ultra resolution line stage we open a new chapter. It offers an unique NOS ladder DAC with 3 digital Inputs without typical Delta/Sigma converting - perfectly integrated into this concept without any compromises. Matching up to the musical analog reproduction was the most important part when we designed the DAC into this machine. True TIDAL performance in convertig digital-to-analog. The other heart of the Preos-D, its extraordinary phono amplification circuit, incl. a phonoboard heating and thermo control, which is an integral part of the overall concept, built to do justice to reference status MC cartridges. The MC phono input is finely adjustable and is meant to be used with the best analog front-ends on the planet, nothing less. Because of its infinitesimally fine resolving power, the Preos-D occupies a quite exceptional position among pre-amplifiers. Prepare for acoustic revelation, since the Preos is built to withdraw maximum information from any system's source. It doesn't do anything but change the volume and select a source. A sonic fingerprint of its own is absent and any loss of fine detail as well.
