Streamers
What is a Streamer?
A streamer is a device designed to play digital music files and stream content from services like Spotify, Tidal, Qobuz, Deezer, or local servers (NAS). They often include advanced features such as built-in DACs, compatibility with high-resolution formats, and expanded connectivity.
Features of Streamers
Network connectivity: Access to the internet via Wi-Fi or Ethernet to play music from cloud services or local networks.
Built-in DAC: Some streamers feature a high-quality digital-to-analog converter (DAC) for signal conversion.
Compatibility with streaming services: Access to popular platforms and high-resolution files like FLAC, DSD, or MQA.
Control interfaces: Can be controlled via mobile apps, remote controls, or even voice assistants.
Audio outputs: Options to send analog signals (with DAC) or digital signals (to use an external DAC).
Advantages of Having a Streamer in Your Audio System
Many support high-resolution playback, offering quality that can surpass CDs.
Access millions of songs from streaming services or local files without handling physical discs.
You can pair the streamer with a DAC or amplifier of your choice.
Manufacturers often add new features and compatibility through updates.

Factors to Consider When Buying a HiFi Streamer
Ensure it supports the services you use (e.g., Tidal, Spotify).
DAC quality (if integrated): If you do not plan to use an external DAC, this component is critical.
Make sure the outputs (analog/digital) match your system.
An intuitive app or integration with voice assistants can enhance your experience.
