HiFi Rose RS520 Integrated Amplifier & Streamer

The HiFi Rose RS520 is more than just a source device with a built-in amplifier. It is a true all-in-one product with each stage expertly specified to deliver a performance that rivals multi-box systems. Even when matched with larger or more “difficult” speakers, it delivers a more delicate and elegant sound quality that is controlled and uniform across the frequency range.

At the centre of the RS520 is ROSE OS, HiFi Rose’s Android-based operating system, which opens up a world of music and video to your streamer.

Rose OS allows users to play music and video files from a local storage device (USB, MicroSD or SATA), or access files elsewhere on your home network with a DLNA connection to any NAS drives or other storage devices. The Music app gives a clean presentation of all your connected music sources and is easy to navigate and use. Rose OS also features built-in apps for Tidal, Qobuz and Apple Music – giving complete access to their extensive streaming libraries. The Tidal app even gives access to the service’s music video streaming content for playback on the RS520 screen or via the HDMI output. On top of this already impressive feature set, the RS520 is also an MQA decoder, for full playback of Tidal Masters tracks.

The HiFi Rose RS520 is a true full-feature product, but designed in a way to deliver a pure, warm sound that can typically only be experienced from an expensive separates system. With the added benefit of Rose OS, it is not just a series of convenient features forced together, it is a meticulously engineered device that offers every feature in the highest possible quality.
