About the Rossini Apex
The dCS Rossini APEX is a reference-class upsampling network DAC built around dCS's proprietary Ring DAC, upgraded in 2022 with the latest-generation Ring DAC APEX hardware — a revised reference supply, enhanced filter, summing and output stages, and an all-new output stage for lower distortion and improved linearity. It combines a high-end DAC with a full network streamer: PCM playback to 24-bit/384kHz and DSD128, streaming from TIDAL, Qobuz, Deezer and internet radio via the dCS Mosaic control app, plus Roon Ready, AirPlay, Spotify Connect and UPnP support. The Rossini APEX is hand-assembled at dCS's headquarters in Cambridgeshire, UK, and housed in a precision-machined aluminium chassis available in silver or black.
