A very complete, modern and affordable solution in equal parts to access new digital audio without complications: this is what Pro-Ject offers us with its new Stream Box S2 Ultra, a “streamer” awarded by the prestigious association of publications specialized in consumer electronics, EISA, as a consequence of its exceptional flexibility and high musicality. With a compact all-metal enclosure and a low-noise external power supply, the Stream Box S2 Ultra offers modern connectivity embodied in its inputs for networking and a USB A output. Of the aforementioned USB output, it is important to note that its circuitry It has been perfected for audio signals, using a dedicated power supply and containing only audiophile-grade components. In addition, the user will not have to worry about possible problems related to compatibility with different digital files, since the Stream Box S2 Ultra sends them directly to the DAC. On the other hand, since most DACs on the market only include a USB input, Pro-Ject has designed its new “streamer” to also perform the functions of a USB “detox” device. This means that it will be enough to connect our PC to the USB B Micro input of the device and then connect our DAC to the audio output, thus cleaning the usually noisy signal coming from said PC. Let us finally point out the presence of an HDMI output for viewing content, as well as the possibility of controlling the Stream Box S2 Ultra with a dedicated “app” for iOS/Android, based on an open source project that guarantees extensive support and future improvements. .
