The dCS Rossini DAC makes superlative sounding music from a wide range of digital sources, simply integrating your digital music and setting the performance standard for digital playback. This single-box digital music player features the legendary dCS Ring DACTM and signal processing platform plus a custom high performance UPnP music streamer.
Rossini plays music through an array of industry-standard USB, AES and S/PDIF digital inputs, and can stream over Ethernet from a NAS drive or online music services such as TIDALTM, QobuzTM, DeezerTM, SpotifyTM, Internet Radio and from Apple devices via AirplayTM .
Designed for flexibility and ease of use without compromise, Rossini uses the very latest dCS Digital Processing Platform and Ring DACTM technology, originally developed for the flagship Vivaldi series. Its single FPGA brings improved signal processing and superior flexibility, effectively making it future-proof.
Rossini DAC has a powerful new user interface, plus a custom control app that lets listeners manage their music playback from any source in an elegantly simple way – accessing music streaming services, digital and UPnP sources from one control point. The Rossini app also features an intuitive install and configuration wizard for ease of set-up.
Featuring DXD upsampling as standard, the multi-stage oversampling design offers optional DSD upsampling plus an extensive selection of DSP filters to suit individual taste and music choice. The network streaming functionality within Rossini DAC is unparalleled in its processing power and jitter performance, and currently runs at up to 24-bit, 384kS/s and DSD128, supporting all major lossless codecs, plus DSD in DoP format and native DSD.
Rossini supports the simple yet highly effective dCS ‘auto clocking’ architecture as used in Vivaldi, which minimises jitter and improves sound quality significantly.
Designed and made in Great Britain to the highest standards, Rossini’s elegant chassis uses aerospace-grade machined aluminium with internal acoustic damping panels to reduce sound-degrading mechanical vibration and magnetic effects. Multi-stage power regulation is employed, with twin mains transformers to isolate the analogue, digital and clock circuitry.
