PrimaLuna ProLogue Classic CD Player

The SuperTubeClock™ replaces the standard solid-state clock with a vacuum tube circuit. This reduces jitter and improves the precision of the digital-to-analog conversion, resulting in greater resolution, detail, and a more natural sound profile.

Yes, the ProLogue Classic features a high-resolution USB digital input. This allows you to connect a computer or other digital transport to utilize the player's internal Burr Brown PCM1792 DAC and tube-based output stage.

By using completely independent circuitry for the left and right channels, including dual vacuum tube rectification, the player achieves superior channel separation. This results in a wider, more stable soundstage and improved imaging.

Point-to-point wiring eliminates the need for printed circuit boards in the signal path, which can often degrade signal integrity. This traditional construction method ensures a cleaner, more direct path for the audio signal, contributing to the player's overall clarity.

The unit uses a specific tube complement of 12AX7, 12AU7, and 5AR4 tubes. PrimaLuna has incorporated features to extend tube life, but like any tube-based component, you should expect to replace them periodically as they naturally wear out over time.

Because this player uses vacuum tubes, it generates heat during operation. It should be placed on a stable surface with adequate airflow around the chassis to ensure the components remain within their optimal operating temperature range.
