RS520
ROSE RS520 it's more than just a source device with a built-in amplifier. It's a true all-in-one system, where every element has been expertly engineered to deliver performance that rivals multi-unit systems. Even when paired with larger or more "difficult" speakers, it offers a more refined and elegant sound quality that is controlled and uniform throughout the frequency range.
Solid foundations
The four surfaces of the RS520's elegant housing are machined from a single piece of high-strength aluminum, reducing the number of separate parts needed to produce the bodyshell. This "one-piece" manufacturing method dramatically reduces the risk of vibration transfer through the body and minimizes standing waves, which can affect final sound quality.
Like all Rose streamers, the RS520 is recognizable above all by its large multi-touch screen . At 12.6 inches wide, the 1920 x 515 resolution LCD panel offers a razor-sharp display that's easy and a pleasure to interact with for complete control of your listening experience. The main transport controls are also located on the top of the RS520 for ease of use.
