In this Pro-Ject CD Box RS2 Tube Review, we explore how Pro-Ject’s top-loading CD player marries the pinpoint accuracy of digital playback with the lush warmth of vacuum tubes. The CD Box RS2 Tube is a tour de force, boasting a Red Book SUOS DM-3381 drive, a Texas Instruments PCM1796 DAC in fully differential mode, and a fully balanced tube output stage—all within a sleek aluminium chassis.
Why the CD Box RS2 Tube Stands Out
The CD Box RS2 Tube is the first RS-line player to integrate a high-end DAC. Key highlights include:
-
Precision CD Transport: The new SUOS DM-3381 Red Book drive with BlueTiger CD-88 servo delivers low-jitter playback with a robust, vibration-damped chassis and top-loading aluminium cover plate.
-
Legendary DAC: Texas Instruments PCM1796 in fully differential configuration ensures exceptional linearity, ultra-low distortion and an open, transparent soundstage.
-
Balanced Tube Output: Dual E88CC tubes in a fully balanced output stage breathe life into recordings, adding warmth and natural harmonic richness without sacrificing detail.
-
Versatile Connectivity: Balanced XLR and unbalanced RCA analogue outputs, plus optical and coaxial digital outputs for use as a standalone CD transport.
-
Gravity Design Chassis: Central mass point and full aluminium casework reduce vibration, ensuring stable playback and clean audio.
Who Should Consider the RS2 Tube?
The Pro-Ject CD Box RS2 Tube Review highlights its appeal for:
-
Audiophiles seeking a CD player that balances technical excellence with emotional engagement.
-
Tube Enthusiasts who want a genuine valve stage, not just a cosmetic effect.
-
Digital Purists looking for a high-performance DAC inside a premium CD player.
-
System Upgraders after a reliable European-made component that can double as a transport for future DACs.
