The Phono Box S3 B is a compact, affordable moving magnet and moving coil phono stage with dual-mono layout, discrete circuitry and balanced inputs and outputs.
With its spacious, minimalist design layout, it is easily customisable to suit any connected cartridge, and offers unrivalled value for money and performance when connected to any matching analogue hi-fi system.
The Pro-Ject design team took the decision to employ fully symmetrical and discrete circuitry in the gain stage of the Phono Box S3 B. Discrete circuits involve no operational amplifiers (op-amps), and the result is a more neutral, natural, dynamic, and vivid sound. They are more complicated to put together and involve a greater variety of components, but the result when utilised in a well-organised electrical layout is a true high-end sound.
The Phono Box S3 B is extensively customisable so suit the moving magnet or moving coil cartridge it is connected to. With five Impedance (Ω), four Capacitance (pF) and four Gain options on offer, there are very few cartridges this box of tricks cannot accommodate.
As the Phono Box S3 B is equipped with both balanced inputs and outputs, it is also part of Pro-Ject’s True Balanced Connections concept. By connecting to a turntable with a moving coil or specially designed moving magnet cartridge, and using one of Pro-Ject’s balanced connection cables, your analogue system can benefit from increased dynamics, less noise and improved signal-to-noise ratios. Going true balanced is like hearing parts of your music that were not there before.
This requires engineering that has never been seen at this price point and opens up iconic mid-level turntables, such as the Debut Evo 2, to the benefits of True Balanced Connections.
Elsewhere in the Phono Box S3 B design, the semi-passive RIAA equalisation stage is optimised for absolute accuracy and signal integrity. Depending on the outputs you are using, this stage is then either directly fed to the output stage (when using RCA outputs) or is connected to a balancing stage for onward balanced connections.
The Phono Box S3 B is finished in a steel chassis, covered by silver or black aluminium panels, for extreme rigidity and good electrical isolation. The neat minimalist aesthetic allows for good spacing between controls on the front panel and connections on the back panel, despite its smaller size. It also features an external power adapter, to keep the sensitive internal signals free from any interferences.

Pro-Ject was founded in 1991, during the onslaught of the compact disc and CD players, with the mission to offer the best analogue experience for reasonable prices. In a time where the digital audio media had been on the rise, and vinyl was declared as outdated and dead, Heinz Lichtenegger kept his belief in the simple but best way to enjoy music – turntables.
Pro-Ject’s aim is to get as many people as possible into the wonderful hobby that is HiFi audio and to deliver a real stereo experience for the lowest cost possible. The best way to start there is with a proper turntable. They want to give music lovers the right to choose what they need by not overblowing their products with unnecessary features. They strive to create astonishing products that offer impeccable value by using the best components for the price and manufacturing their handmade goods in Europe.

Revelation Audio is more than just a HiFi store — it’s a destination for anyone who believes music deserves to be heard exactly as the artist intended.
Located in the heart of historic Lincoln at 50 Grantham Street, LN2 1LW, our showroom occupies a stunning 15th-century Grade II listed building. We’ve created a relaxed, home-from-home environment where you can experience premium audio systems the way they’re meant to be enjoyed — without pressure, in comfort, and with exceptional coffee always on hand.
Founded by David McCaffrey, Revelation Audio brings together over 20 years of deep experience in the audio-visual industry. David has worked with some of the world’s most respected brands — including Arcam, Tannoy, Panasonic, Sony, and JBL — giving him unparalleled insight into what truly delivers outstanding sound quality.
After two decades helping shape the industry, David opened Revelation Audio to focus on what matters most: carefully curated, high-performance audio solutions tailored to real people and real listening spaces. We specialise in both analogue and digital sources, state-of-the-art amplifiers, and loudspeakers that reveal every nuance of your music.
My passion for music runs deep and has been the driving force behind everything I do at Revelation Audio. For me, music isn’t just background noise — it’s emotion, storytelling, energy, and escape all at once. I love how a perfectly reproduced track can transport you, make your heart race, or bring tears to your eyes. Some of my favourite artists right now include Karsh Kale for his groundbreaking fusion of Indian classical with electronic grooves, Etherwood for those soulful, atmospheric drum & bass journeys, and Tom Misch for his effortless blend of jazz, soul, and groove. But my tastes are truly eclectic — one minute I’m deep into jazz fusion or classic rock, the next I’m exploring ambient electronica, vintage soul, progressive metal, or world music from every corner of the globe. That wide-ranging love is exactly why I’m so committed to systems that can handle anything you throw at them with honesty, detail, and musicality.
