In true PrimaLuna fashion, the stunning ProLogue Classic CD Player revolutionized the audio industry by introducing the world's first tube-based data clocking device: the SuperTubeClock™.

By incorporating a low-noise mini-triode vacuum tube into the digital clock, this boldly conceived design provides vastly superior resolution, detail retrieval, improved clarity, increased definition and detail from top to bottom.

The ProLogue Classic CD Player is a true dual-mono design, right down to the dual vacuum tube rectification - another first in a CD player. The power supply is adapted from the award winning ProLogue Three preamp. High quality resistors, mosfets, and Solen capacitors yield superior transient response, detail, and channel separation.
