I am running Roon Core on a Nucleus server without problems. The primary endpoint is my Marantz AV8801. It took a while, but now everything runs pretty well.
I would like to put an endpoint in my bedroom. It would be nice if things could be kept simple, e.g., one box that would be able to pick up the Roon signal, amplify it and output it via a built-in speaker.
I have thought about getting a Squeezebox device on Ebay but I worry about putting work into a piece that is getting old and is no longer supported. I understand an Apple HomePod would also work but I’m not sure I want Apple to have a microphone in my bedroom.
Addon T10 (NOT the C10), a Raspberry powered by the USB port, and your choice of compatible HAT (the cheaper the better, they’ll all be good enough).
Libratone Zipp 2 is one of my favourites as it’s portable (built in battery) and works well with AirPlay which Roon uses to send the data.
Sound quality is quite good for a WiFi speaker and sound level can be quite loud!
I just picked up the Bowers and Wilkins Formation Wedge. It’s definitely “different” looking but it sounds fantastic. Auditioned it against Bluesound 2i and Sonos Play:5 and it blew them away in sound quality. At $899 it’s an investment but it’s well worth it if you want a self-contained Roon endpoint with no mic. Good luck!
