HiFi Rose RS520 All-In-One Streaming Amplifier

Four surfaces of the RS520’s elegant housing are made from one piece of high-durability aluminium, reducing the number of separate parts required to produce the casework. This “one piece” production method dramatically reduces the risk of vibrations transferring through the body and significantly reduces standing-waves, which can affect the end sound quality.

Like all Rose streamers, the RS520 is most identifiable by its large multi-touch screen. Measuring 12.6” wide, the 1920 x 515 resolution LCD panel provides a crystal-clear display that is smooth and enjoyable to interact with for complete control of your listening experience. Core transport controls can also be found on top of the RS520, for ease of use.
