While reading through another thread, and doing some research as a result, I discovered the SonicTransporter I5 music server, sold by Small Green Computer.
A nice feature of the SonicTransporter I5 ($999 including 1TB SSD) over a Roon Nucleus is that if you decide to cancel Roon, the SonicTransporter I5 doesn’t become a brick like the Nucleus, since the SonicTransporter I5 is pre-loaded with HQPlayer (embedded), Squeezebox Server, Plex Media Server and MinimServer (DLNA server) in addition to Roon Core Server.
https://www.smallgreencomputer.com/collections/audio-server/products/sonictransporter-i5?variant=208...Since the Roon Nucleus and SonicTransporter I5 are both Intel i5 computers, I see no reason why they wouldn’t sound identical on a network.
