Imagine having a single device that seamlessly connects all your audio sources—vinyl, TV, streaming, and headphones—into one sleek, compact hub. Sounds too good to be true? Well, Pro-Ject’s new Pre Box S3 stereo preamplifier is here to make that a reality. But here’s where it gets controversial: can one tiny box truly handle the demands of modern hi-fi enthusiasts without compromising quality? Let’s dive in.
Austrian audio powerhouse Pro-Ject has unveiled the Pre Box S3, a versatile stereo preamp designed to simplify the lives of audiophiles juggling multiple audio sources. This all-in-one solution combines a stereo preamp, DAC (Digital-to-Analog Converter), and headphone amplifier into a single, stylish aluminium chassis. The goal? To centralize your audio setup, allowing you to connect all your sources to one device and pair it with either active speakers or a power amp and passive speakers. It’s a minimalist’s dream—but does it deliver?
And this is the part most people miss: Despite its small size, the Pre Box S3 is a connectivity powerhouse. Pro-Ject boasts an impressive 13 inputs and outputs, ensuring compatibility with virtually any audio source. Here’s the breakdown: two RCA line inputs, a moving-magnet phono stage for turntables, optical and coaxial digital inputs, USB-C for computers and mobile devices, and an HDMI eARC input for direct TV audio. Plus, there’s Bluetooth 5.0 with aptX HD for wireless streaming that doesn’t skimp on quality. On the output side, you’ll find variable and fixed RCA outputs, a dedicated subwoofer output, and a 6.3mm headphone jack. Even custom installers will appreciate the 12V trigger and RS232 connections for multi-room setups.
Under the hood, the Pre Box S3 features a dual-mono design and a Cirrus Logic DAC that supports high-resolution audio up to 24-bit/192kHz. This means it can handle hi-res downloads and lossless streaming from services like Tidal and Qobuz with ease. Here’s the bold move: Pro-Ject opted for a motorised analogue volume control instead of a digital one, a nod to purists who swear by a traditional signal path. But is this a step forward or a nostalgic misstep? Let’s discuss.
The compact aluminium chassis isn’t just for looks—it’s designed to minimize interference and seamlessly match Pro-Ject’s S-series components, like the Amp Box S3. Available in black or silver, the Pre Box S3 is priced at £499 / US$699 / €599 internationally, though Australian pricing is still pending. The big question: Is this the ultimate audio hub, or does its ambition outpace its execution? Share your thoughts below—we’re eager to hear your take!
