This new Digital/Analog-Converter TUBE-DAC II has been engineered by Accustic Arts' labs, the TUBE-DAC II is an hybrid concept featuring a tube pre-amplifier system. This concept combines the advantages of the solid state technology with the advantages of the tube principle, however without the specific disadvantages of tubes.

The DAC employs a special and unique 2x 32-Bit technology with simultaneous digital signal processing, separately for left and right channel and an high precision crystal oscillator. After conversion the analog signal processing is based on the tube-hybrid concept. In this concept the tube is used only where it makes sense physically and soundwise, which is the second stage of our analog filter stage, a so called "GIC filter". Then the impedance conversion stage operates with ten pieces of the world-wide renowned Burr Brown amplification chip OPA627.

The TUBE-DAC II provides 3x digital inputs, 2x digital outputs and balanced XLR-outputs as well as unbalanced RCA outputs.
