The Stream Box S2 Ultra is designed to bring high-end network connectivity to any USB-enabled DAC. Rather than having to consider expensive or inconvenient upgrades, the small size and attractive price of the Stream Box S2 Ultra means you don’t need to change your system to enjoy wireless (or wired) streaming from any DAC with a USB input. The USB output of the Stream Box S2 Ultra is meticulously engineered to offer the very best possible output signal. With its own dedicated internal power supply and premium components, the USB output “detoxes” the USB signal, removing noise and unwanted artefacts. The end-result is a sound presentation that is open, clean and detailed, but retaining the raw emotion of the music. Foremost as a Roon Ready network streamer, the Stream Box S2 Ultra is effortlessly simple to integrate. It’s instantly recognised by your Roon server once connected to a USB DAC, so you can transmit via Roon’s bespoke RAAT protocol and experience the full Roon experience from any existing, non-Roon-certified equipment. Second, as a universal network bridge it offers a sophisticated solution for building a small music server based on the popular Volumio platform. Volumio allows for playback from Spotify, Tidal, Qobuz, Shoutcast (Internet Radio) and Shairport (Airplay), as well as UPnP network services or attached USB hard drives. Controlled over IP via the responsive in-browser app, or by using Pro-Ject’s own Pro-Ject Play Android app, the Stream Box S2 Ultra is easy to navigate and enjoy – delivering its class-leading digital audio output signal no matter how you choose to use it. The Stream Box S2 Ultra supports almost any file-type that your DAC does, opening up the option to handle even very high-resolution file types like 352.8kHz PCM and DSD256. If your DAC is MQA-enabled the Stream Box S2 Ultra can pass-through MQA signals without alteration, for exact unfolding by your DAC. The Net/PC button also allows for a PC or Server to be directly connected via USB – benefiting from the same USB detox process without the need to send signals over a wireless or wired network. The Stream Box S2 Ultra is a cutting edge piece of kit. Capable of opening up new possibilities on even ultra-high-end DACs, or for simply building a small, bespoke audio streaming platform, its class-leading, high-end technology and compact footprint make it a must-consider add-on for any serious digital audiophile.
