I highly recommend Innuos Zenith MK3 as the streamer. It is an excellent server, steamer, Cd ripper, and plenty of local storage. If you ever want to get into Roon, it can act not only as a Roon endpoint but also Roon core server.
Secondly, it’s Sense 2.0 software sounds very good — better than Roon according to many people here, including myself. Innuos has been around for a few years now and their products are rock solid with excellent customer support.
