For any new to the topic, "Network Bridge" is also often referred to as "Network Player" or "Renderer", providing the ability to play any digital file on a network or local drive and send the digital output to a DAC.
"Streamer" is often mentioned interchangably, but streaming more specifically is taking the digital file from an internet-based service like Spotify, Qobuz or Tidal. All streamers don't have connectivity to networked drives of your own library. Some have internal drives built-in, optional or can be connected directly via cables.
@ianrmack for cost effective/high-quality, one vote here for Sonore products. If budget is very tight and you're DIY-inclined, Raspberry Pi is a sub-hobby into itself. For easy/peasy on modest budget, Blusound Node variants seem to be the "Toyota Corolla" of the category.; proven/functional/decent. Cheers,
