Rediscover Your CDs with the Pro-Ject CD Box RS2 Tube: Precision Meets Musical Warmth

Pro-Ject Audio Systems have introduced a new benchmark in high-end audio: the CD Box RS2 Tube, the latest addition to their flagship RS2 series. This premium player combines a dedicated CD transport, a fully balanced valve (tube) output stage, and an integrated high-end DAC, delivering exceptional playback quality and the tactile pleasure of physical media.

Why Choose a Dedicated CD Transport?

Unlike multi-format players that juggle CD, DVD, and Blu-ray playback, the CD Box RS2 Tube is engineered for one purpose: extracting every bit of data from your CDs with uncompromising accuracy. This focus ensures cleaner, more reliable performance for true audiophiles.

Precision Engineering at Its Core

At the heart of the CD Box RS2 Tube is the SUOS DM-3381 Red Book CD drive, a high-precision mechanism crafted from robust aluminium to minimise vibration and mechanical interference. Developed by SUOS-HiFi, formerly StreamUnlimited Optical Storage and founded by ex-Philips engineers - the drive works in harmony with the BlueTiger CD-88 servo, maintaining flawless tracking and reducing read errors for pristine digital data delivery.

Valve Output for Natural Musicality

A standout feature is the fully balanced tube output stage, employing two premium E88CC vacuum tubes. While the digital signal remains untouched, the analogue output gains warmth and fluidity, creating a sound that feels organic and expressive - closer to the experience of vinyl.

The Enduring Appeal of CDs

In an era dominated by streaming, CDs remain a permanent, tangible format. The CD Box RS2 Tube celebrates this legacy, offering playback that combines digital precision with analogue-like warmth. For those with extensive CD collections, it’s the perfect way to rediscover your favourite recordings. The Pro-Ject CD Box RS2 Tube is now available for order in the UK.
