The Pro-Ject CD Box S3 is a compact player and the first model in Pro-Ject’s new S3 line. It combines a small footprint with high-quality sound performance. With its aluminum chassis, slot-in mechanism, and high-resolution DAC, it delivers a listening experience that meets audiophile standards while taking up minimal space in your setup. Designed and manufactured in Europe, this CD player demonstrates that the CD format remains relevant in the modern audio ecosystem.
A Compact and Sophisticated Design
The CD Box S3 immediately stands out for its reduced dimensions. At just 206 mm wide, 55 mm high, and 153 mm deep, this CD player is significantly smaller than a traditional hi-fi component. Its compactness makes it an ideal solution for limited spaces or for those looking to minimize the footprint of their audio system. Despite its small size, the CD Box S3 boasts an elegant presence with its all-aluminum chassis, available in black or silver finishes.
The minimalist front panel houses a 1.54-inch display that shows essential information such as track number and playback time. A notable feature is the screen’s color inversion function, which can be activated by simply holding down the stop button. This allows you to adjust the display to your visual preferences or the lighting conditions in your room.
The slot-in mechanism is another distinctive design element. Unlike traditional trays, this system gently draws the CD into the device, offering smoother handling and reducing the risk of long-term mechanical failure. This technical choice also contributes to the player’s clean, streamlined look.
Audio Performance Optimized for CDs
The CD Box S3 was designed with a clear goal: to deliver the best possible playback of compact discs. Unlike versatile DVD or Blu-ray players, this unit is specifically optimized for playing audio CDs according to the Red Book (CDDA) standard. This specialization ensures a bit-perfect 1:1 reproduction of disc content.
At the heart of the system is a PCM5102 digital-to-analog converter (DAC) capable of handling signals up to 32 bits/384 kHz. This high-quality chip ensures precise conversion from digital to analog, preserving the nuances and details of your recordings. The technical performance is impressive, with a frequency response of 20 Hz to 20 kHz (±0.15 dB), total harmonic distortion of just 0.005% at 1 kHz on the analog output, and a remarkably low noise floor exceeding -120 dB.
Listeners regularly report that the CD Box S3 reveals sonic details they had never heard before in their CD collections. The sound presentation is described as detailed, communicative, and dynamic, with a very well-defined stereo image. Percussive information is particularly well rendered, and the overall listening quality evokes that of a high-resolution system.
Versatile Connectivity and Integration
The CD Box S3 offers remarkable integration flexibility thanks to its dual connectivity. On the back of the device, you’ll find a pair of analog RCA outputs as well as a coaxial S/PDIF digital output. This setup allows you to use the player in two distinct ways.
You can take advantage of the high-quality internal DAC by connecting the analog outputs directly to your amplifier or preamplifier. This simplified approach delivers excellent sound results while minimizing the number of devices in your chain. Alternatively, you can use the CD Box S3 as a CD transport by connecting its digital output to an external converter. This option lets you benefit from the player’s mechanical precision while further customizing the sound signature via your preferred DAC.
This versatility makes the CD Box S3 an adaptable device that can evolve with your audio system. Whether you’re a beginner audiophile with a simple setup or an experienced enthusiast with a high-end external DAC, this CD player will integrate seamlessly into your configuration.
Intuitive Operation with a Few Particularities
The CD Box S3’s user interface prioritizes simplicity. Essential controls are accessible via the front panel buttons: power, play/pause, previous/next track, and stop/eject. The included remote control adds extra features such as direct track access.
A few usage particularities have been noted by users. The front panel buttons require a full, firm press to operate correctly. It’s not so much about applying a lot of force as it is about pressing evenly all the way down. This may take some getting used to, but quickly becomes second nature with regular use.
The remote control, while functional, has a compact and lightweight design that may surprise users accustomed to more substantial remotes. It uses two AAA batteries and is highly responsive, working effectively even when not pointed directly at the device.
Disc loading times are impressively short, with playback ready in just 3 to 5 seconds after insertion. This responsiveness contributes to a smooth and enjoyable daily user experience.
