For audiophiles, the quest for the perfect sound system often involves a tangle of wires and a collection of specialized components. Pro-Ject, the Austrian audio company, consistently offers a solution: a compact, all-in-one box designed to address specific audio needs. Their latest offering, the Pre Box S3, aims to be the central hub for modern audio setups, seamlessly bridging the gap between analog and digital sources.
The Rise of the Integrated Audio Hub
The Pre Box S3 isn’t launching in a vacuum. It’s a response to a growing trend: the desire for simplified, yet high-performance audio systems. Consumers are increasingly looking for solutions that minimize clutter and complexity without sacrificing sound quality. According to a recent report by the Consumer Technology Association (CTA), the market for integrated audio systems grew by 15% in 2023, driven by demand for convenience and multi-room audio capabilities. This shift is fueled by the proliferation of streaming services and the integration of audio into smart home ecosystems.
Connectivity is King: A Deep Dive into the S3’s Ports
The Pre Box S3 boasts an impressive array of connections. On the analog side, you’ll find two line-level inputs and a dedicated Moving Magnet (MM) phono input – a nod to Pro-Ject’s roots in vinyl playback. However, it’s the digital connectivity that truly sets this unit apart. Optical and coaxial inputs cater to traditional digital sources, while USB-C provides a direct link to computers for high-resolution audio. Bluetooth offers wireless convenience, and crucially, the inclusion of an HDMI eARC port allows for seamless integration with modern televisions, enabling control via the TV’s remote.
Guide: The Amplifier – The Heart of Your Stereo System
The amplifier is the central component of a classic stereo system, collecting audio from various sources and boosting the signal to drive your speakers.
Beyond the Basics: Features for the Discerning Listener
The Pre Box S3 isn’t just about connections; it’s about versatility. Variable and fixed line outputs provide flexibility for connecting to power amplifiers or active speakers. A dedicated subwoofer output allows for enhanced bass response. A front-panel 6.3mm headphone jack transforms the unit into a capable headphone amplifier. Furthermore, the inclusion of a 12V trigger and RS232 control opens up possibilities for custom installations, allowing the unit to be hidden away and controlled remotely.

The Future of Audio Integration: What’s Next?
The Pre Box S3 exemplifies a trend towards greater integration and simplification in audio. Looking ahead, we can expect to see even more features packed into these compact hubs. Here are a few potential developments:
- Advanced Room Correction: Built-in room correction technology, like Dirac Live, will become more common, automatically optimizing sound for the specific acoustics of your listening space.
- Voice Control Integration: Seamless integration with voice assistants like Amazon Alexa and Google Assistant will allow for hands-free control of your entire audio system.
- Modular Designs: The ability to add modules to expand functionality – perhaps a dedicated DAC or a streaming module – could offer greater customization.
- Increased Focus on Sustainability: Manufacturers will likely prioritize energy efficiency and the use of sustainable materials in the production of these devices.

Pricing and Availability
The Pro-Ject Pre Box S3 is available now, finished in either black or silver. It carries a European price tag of 599 Euro, which translates to approximately 7,000 Swedish Krona. This positions it firmly in the mid-range of the integrated audio hub market.
Did you know? The inclusion of HDMI eARC is a game-changer, allowing you to leverage your TV’s audio processing capabilities and control the volume with your existing remote.
Pro Tip: When connecting multiple sources, experiment with the different input settings to find the optimal sound quality for each device.
