I was in a similar boat and wanted a streamer that sounded better than the RPi and Node. Was going to try the Primare NP5 but went with the Lindemann Bridge II.
It’s a German brand. Looks like a little box but don’t be fooled, high end engineering. Noticeably better sound. Lindemann also have one of the best apps in the streaming game.
I then upgraded the power supply to a price appropriate match, the Farad Super 3, which raised things again.
I don’t know how well this combo competes with expensive streamers. But it killed, for example, the streaming section of the Naim Uniti Atom Headphone Edition, which was a shame because that product was so cool, but the Naim internal streamer could not even come close to the Lindemann/Farad combo.
