Description

Reference-Class CD Playback with Tube Balance

The CD Box RS2 Tube represents the newest addition to the flagship RS2 series, combining refined engineering with an unmistakably audiophile focus. Sharing the same ultra-elegant full aluminium enclosure, it introduces a fully balanced tube output stage paired with a high-end top-loading Red Book CD mechanism. It is the first RS-series CD player to feature an integrated digital-to-analogue converter. Design consistency across the RS2 range is fully preserved. Visual integration within premium systems is effortless.

Integrated DAC with Differential Architecture

Unlike previous models, the CD Box RS2 Tube incorporates an internal DAC based on the Texas Instruments PCM1796 chipset. This high-performance converter operates in a fully differential configuration to directly feed the balanced tube output stage. Signal symmetry is maintained throughout the conversion process. Digital precision and analogue musicality are carefully aligned. Component selection reflects strict audio-grade standards.

Precision SUOS DM-3381 CD Transport

At its core, the player utilises the SUOS DM-3381 Red Book CD-DA drive, engineered for exceptional mechanical stability. The low-vibration disc mechanism significantly reduces jitter and suppresses unwanted noise during playback. A rigid, vibration-damped chassis further enhances operational consistency. Long-term reliability is prioritised. Playback accuracy remains stable over extended use.

Intuitive Operation and Clear Display

User interaction is handled via front-panel controls or the supplied full aluminium remote handset. A large RS2 LCD display presents all relevant playback information, including artist and track data when CD-Text is available. Readability is optimised for distance viewing. Interface logic remains straightforward. Daily operation is comfortable and predictable.

Fully Balanced Tube Output Stage

Vacuum tubes have been a defining element of the RS line since its inception. The CD Box RS2 Tube features a fully balanced output stage equipped with two premium E88CC tubes. This advanced tube buffer enhances tonal richness, fluid dynamics, and harmonic realism. The sonic presentation feels natural and engaging. Digital harshness is effectively avoided.

Musicality Through Analogue Refinement

The tube output stage imparts warmth and organic flow without sacrificing resolution. Harmonic textures are reproduced with authenticity, lending music a more lifelike character. This approach offers a clear contrast to the often clinical nature of conventional digital players. Listening fatigue is reduced. Emotional involvement is increased.

Robust Mechanical Design Philosophy

The top-loading drive uses an aluminium cover plate and magnetic clamp to ensure disc stability. A gravity-based layout with a central mass point improves vibration control. Structural rigidity supports consistent performance. Mechanical resonance is minimised. Design choices directly support sonic purity.

Connectivity and System Integration

In addition to its analogue outputs, the CD Box RS2 Tube provides both optical and coaxial digital outputs. This allows flexible integration into external DAC-based systems if required. Output options remain versatile. System matching is straightforward. Future upgrades are supported.

European Manufacturing and Finish Options

The unit is manufactured in Europe and reflects high production standards throughout. It is available in either silver or black to match existing RS2 components. Material quality is immediately apparent. Build tolerances are precise. Longevity is a core design objective.
