TIDAL PREOS

 

State-of-the-Art MC-phono, a most exquisite non-oversampling ladder DAC and classic line level inputs: three times reference level in one device - the 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 by adding a DAC into it. 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 extraordinary phono amplification circuit does include a phonoboard heating and thermo control, which is an integral part of the overall concept. It is 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.
