Frequently Asked Questions

What is the difference between the RS250A and the previous model?

The RS250A is an evolution of the RS250, featuring notably a more powerful ESS ES9028Pro DAC (versus an ES9038Q2M on the RS250), extended support for high-resolution audio formats, and an improved user interface. The overall design and basic features remain similar.

How does network playback work with the RS250A?

The RS250A can access music files stored on a NAS or computer via the local network (Ethernet or Wi-Fi). It supports SMB, FTP, and WebDAV protocols for file sharing. Additionally, it can play music from streaming services like Qobuz, Tidal, or Spotify via the Internet.

What types of audio and video files are supported?

The RS250A supports a wide range of audio formats, including WAV, FLAC, ALAC, AIFF, MP3, AAC, DSD (up to DSD512), and MQA. For video, it can play common formats like MP4, MKV, AVI, as well as H.264 and H.265 codecs up to 4K 60 fps.

Can the RS250A be used as a preamplifier?

Yes, the RS250A has a variable-level analog output that can be connected directly to a power amplifier or active speakers. The volume can be controlled via the device’s interface or the remote control.

How does it compare to other high-end network players?

The RS250A stands out for its large touchscreen and versatility (audio and video). Its audio performance is on par with the best network players in its price category. It also distinguishes itself through its significant internal storage capacity and compatibility with numerous streaming services.

What are the remote control options?

The RS250A can be controlled via its touchscreen, the included Bluetooth remote control, or the Rose Connect mobile app available for iOS and Android. Additionally, being Roon Ready, it can be integrated into a Roon system and controlled via the Roon interface.

Is the RS250A compatible with home automation systems?

The RS250A does not have integrated home automation features. However, its compatibility with protocols like DLNA and AirPlay allows it to be integrated into certain home automation ecosystems. For more advanced integration, third-party solutions using IP control could be considered.

A nice Swiss army knife that delivers great sound and component/material quality... But the apps are not easy for the average person to use, with too many features.

Un joli couteau suisse performant en son et qualité des composants et des matériaux… Mais les applis ne sont pas faciles à utiliser pour le commun des mortels, trop de fonctionnalités.
