Austrian audio brand Pro-Ject has unveiled two new devices aimed at modernising traditional hi-fi systems, bringing wireless streaming and multi-room audio into legacy setups without a full overhaul.

The Stream Box E and Wireless Box E both run on the WiiM OS platform, positioning them within a growing ecosystem of affordable, app-controlled audio products that rival offerings from Sonos and Bluesound.

The Stream Box E is the more versatile of the pair, functioning as both a network streamer and digital preamp. It enables access to popular services including Spotify Connect, Tidal Connect and Qobuz, while also supporting multi-room playback. Users can integrate it into existing systems, pair it with a power amplifier and passive speakers, or connect it directly to active speakers.

Notably, the device includes an analogue input, allowing sources like turntables to be streamed wirelessly across a home network.

The Wireless Box E (pictured above) takes a different approach, targeting cable-free speaker setups. Designed as a compact mono streaming amplifier, it connects directly to passive speakers via binding posts, eliminating the need for traditional speaker cables. Each speaker requires its own unit, powered separately, enabling flexible placement around the home.

While optimised for Pro-Ject’s own speaker range, the Wireless Box E can also work with third-party speakers, with optional extension cables available for compatibility.

However, Apple users may face limitations, with no confirmed support for AirPlay 2 or Apple Music integration – an area where competitors like Sonos still have an advantage.

The Stream Box E is available now for around A$300, while the Wireless Box E is expected in late May at approximately A$374 per unit.
