Description
Compact Yet High-Performance Design
The HiFi Rose RS250A brings the acclaimed HiFi Rose experience into a refined, compact chassis. Carved from solid aluminum, it minimizes vibration and interference while delivering reference-level digital playback. With a smaller footprint than its flagship siblings, the RS250A is ideal for both desktop setups and full HiFi systems.
Precision Digital Audio
At its core, the RS250A features the ESS Sabre ES9028 PRO DAC, supported by advanced clocking technology for ultra-low jitter and clean, accurate sound. Capable of handling 32-bit/768 kHz PCM and native DSD512, it reproduces your favorite recordings with lifelike depth and clarity. MQA certification and Roon Ready support make it a future-ready hub for high-resolution streaming.
Immersive Touchscreen Control
The front panel is dominated by a vivid 8.8″ full HD touchscreen that provides an elegant and intuitive interface. Album artwork, customizable VU meters, and Rose OS controls are displayed in stunning detail, giving you direct, smartphone-free access to your music and settings.
Expanded Streaming & Connectivity
Stream seamlessly from Tidal, Qobuz, Apple Music, Spotify, and internet radio, or play from your personal library via NAS, USB, microSD, or an optional internal SSD. The RS250A also supports Bluetooth and Wi-Fi for wireless playback, as well as HDMI output for 4K video and HDMI ARC input to upgrade your TV’s audio.
Flexible Storage & CD Playback
Expand your library with ease. The RS250A allows for internal SSD installation, microSD cards, or external drives. Add the optional RSA-780 CD drive to rip your collection into high-resolution files or enjoy real-time CD playback with audiophile precision.
Seamless Integration & Control
With balanced and unbalanced analog outputs, optical and coaxial digital I/O, plus Ethernet for wired streaming, the RS250A integrates smoothly into any HiFi system. Control is flexible through the responsive touchscreen, the RoseConnect app (iOS, Android, PC), or the included remote control
