Pro-Ject Audio Systems has introduced its latest addition to the Box Design series, the Pro-Ject Stereo Box E, a compact and affordable integrated stereo amplifier designed to serve as an entry point for those exploring high-quality audio. Positioned below Pro-Ject’s MaiA S3 range, this model is aimed at listeners looking for versatile connectivity options within a minimalistic, space-saving design.

Measuring a compact 5.1 cm x 20.6 cm x 11.5 cm, the Stereo Box E is designed for flexibility, with a modest power output of 21 watts per channel at 8 ohms, or a total of 42 watts. Though it doesn’t rival the output of higher-end models, the Stereo Box E makes up for it with carefully engineered circuitry inspired by Pro-Ject’s more expensive offerings, aiming to deliver a pure, high-fidelity signal for accurate music reproduction.

Built into a sturdy steel chassis with a brushed aluminium front panel, the unit also features aluminium buttons, balancing durability with a sleek aesthetic suitable for desktop or HiFi rack setups.

The Stereo Box E boasts a robust selection of input and output options, supporting an array of both digital and analog sources. Users will find three analog inputs: an RCA input, a 3.5mm auxiliary input, and a phono input tailored for moving magnet (MM) cartridges, accommodating users with turntable setups.

On the digital side, the unit includes coaxial and dual optical S/PDIF inputs, allowing the connection of digital sources such as streamers or CD transports. Additionally, the unit has a built-in DAC, enhancing audio playback by ensuring high-resolution audio compatibility.

For those who prefer wireless streaming, the Stereo Box E is equipped with aptX HD-capable Bluetooth 5.0, which enables high-resolution streaming from compatible devices. The inclusion of a subwoofer output adds further versatility, allowing users to boost the bass output as needed. 

A 5V/1A USB-C output provides convenient power support for low-power devices like compact music streamers, minimizing the need for multiple power sources and keeping setup clean and simple.

A key highlight of the Stereo Box E is its built-in headphone amplifier, which supports private listening through its 3.5mm headphone jack, adding flexibility for users who want to enjoy high-quality sound without external speakers.

With this headphone capability and its other extensive connection options, the Stereo Box E offers a flexible listening experience suited to various environments, whether as part of a more substantial home system or a dedicated desktop setup. The amplifier is also designed to complement other Pro-Ject products, creating seamless system configurations.

Setting up the Stereo Box E is designed to be intuitive, thanks to its clearly laid-out inputs and outputs. A standard remote control allows easy volume and input adjustments from a distance, while the front-panel controls are simple and effective for quick interaction. The compact design allows it to be tucked away on a shelf or desk without dominating the space, appealing to users who require performance without compromising on space.
