What is your favorite budget streamer?

Can’t say it is my favourite - yet - as I haven’t heard it yet, but on the strength of a long French hifi forum thread singing its praises SQ wise I have a Ustars C19 winging its way here. RPI 4 based with Ropiee pre-installed but you can flash other OS’es if so inclined.

A brand new Bluesound Node 130 can be bought right now for $349.00.

+WiiM Pro, bit perfect digital output to your DAC, software easy to operate, Amazon HD, Qobuz, Tidal, Spotify, Pandora, and more all native in the app. App has both Parametric and graphic EQ if you want to play around a little.

Enjoy the music! 

+++ for Bluesound NODE. It's just been the reliable one amongst my experiments with other streamers. The app is great and well-sorted. The outgoing N130 is being discounted to $349 new. Easy choice. If your DAC does USB Audio, you can output that from the N130 Node as well as coax and optical. 

Node Nano, assuming you do not need to bring the big guns out as per your post, se we are going for convenience, price, and functionality.  Bluesound has the best software in the business, which is why it is so damn popular, you can stream everything to it.  I stream Amazon Music, SiriusXM, and Spotify to mine and a lot of background music from SiriusXM for me.  See link here:  Bluesound music services
