Digital micro preamplifier & Audio optimized network bridge
Pre Box S2 Digital and Stream Box S2 Ultra mark a new era for our S-series components. The Special Chrome Editions of the Pre Box S2 Digital and Stream Box S2 Ultra are beautiful eyecatchers which will fit into any listening environment. The improved aluminium case and board layout result in better shielding of electromagnetical interference. The S2 Chrome Set comes in a high quality wooden box.
For the very first time we are using a dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures highest class audio in a small and affordable package. This DAC is capable of high resolution audio up to 32bit/768kHz PCM and DSD512! Pre Box S2 Digital Chrome is also the very first of our devices to support hardware MQA unfolding. With organic polymer capacitors and thin film miniMELF resistors we were able to create a tiny device that will blow away even much bigger components for a much higher price. With a total of eight digital filters the sound can be shaped precisely to the listeners liking. Pre Box S2 Digital Chrome is fully remoteable, it can also control the playback software of a computer. You can use Play, Pause, Forward and Rewind straight with your Pre Box S2 Digital Chrome!
Stream Box S2 Ultra Chrome closes the gap, it offers modern connectivity with its network inputs and USB A output. This USB output is perfectionized for audio signals, it uses a dedicated internal power supply and only top audiophile grade components. You won‘t run into file-support issues, as Stream Box S2 Ultra Chrome acts as a network bridge, bypassing the files directly to your digital to analogue converter. Since most DACs only have one USB input, we have designed Stream Box S2 Ultra also to be a USB detox device. Simply connect your PC to the micro USB input of the unit and connect our DAC to the audio output. This way you can clean the noisy signal of your PC, while enjoying your music with it. Our new remote control iOS and Android App is based on an opensource project and has a large community behind it. This guarantees full support and future improvements.
This pack includes:
Pro-Ject Stream Box S2 Ultra
Audio optimized network bridge and USB detox device
With the Stream Box S2 Ultra we have designed a completely new product in the streaming world. It features never seen control scenarios and unprecedented audio performance. Its main goal is to be a universal device that can get any USB DAC into the network, upgrading your favourite high-end DAC with modern and future proof streaming capabilities.
With the gaining ground of internet streaming services, such as TIDAL or Spotify, the consumer‘s interest has shifted towards network enabled devices. Many great sounding products though do not offer any network ability, either because they are too old or their main focus was not on this subject. The solution has often been to replace them with a new and modern device, stream audio via Bluetooth or to comprimise and use a smartphone or tablet via their analogue ouput to feed active speakers or amplifiers.
