Pro-Ject – CD Box S2 – Ultra Compact CD Player Review: Big Sound from a Tiny Transport

In this Pro-Ject – CD Box S2 – Ultra Compact CD Player Review, we unpack how Pro-Ject’s smallest CD transport still manages to deliver full-scale audiophile performance. If you’ve been looking for a space-saving solution without compromising on sound quality, this ultra-compact CD player could be your sonic secret weapon.

The Pro-Ject – CD Box S2 is as stylish as it is precise. Enclosed in a CNC-machined aluminium case with matching metal buttons, its minimalist footprint—just 206 × 36 × 142 mm—means it can slot seamlessly into any hi-fi rack or desktop setup. Whether you choose the stealthy matte black or the elegant silver finish, the CD Box S2 looks every bit the part of a high-end component.

Key Features and Technical Highlights

• Mini-PC controlled drive with slot-in mechanism for fast, reliable disc loading
• 32 bit/384 kHz DAC for accurate Red Book playback with selectable FIR and IIR digital filters
• RCA analogue outputs plus optical Toslink S/PDIF digital out—ideal for pairing with your favourite DAC
• Remote control with volume level adjustment when used with Pro-Ject amplifiers

Sonic Performance: Precision Meets Musicality

From your very first track, the CD Box S2 shows off a refined, low-noise presentation. The mini-PC servo drive keeps jitter under tight control, and the internal 32 bit/384 kHz DAC ensures every nuance of your CDs is rendered with clarity. Audiophiles will appreciate the two digital filters—FIR for a more neutral, extended top-end, or IIR for a slightly warmer, analogue-like roll-off.

If you have a flagship DAC in your system, the optical output lets you bypass the onboard converter altogether. This flexibility is perfect for those who want to A/B the internal circuitry against a higher-end external DAC without swapping discs or devices.
