I will second the Wolf. I have a Luna R server with 4TB onboard and it can handle as much external storage as you might want. Dead quiet, wonderful sound quality, exceptional support for Joe P - you cannot do better!
Best server to house Roon and 4 TB of music feeding DCS Vivaldi Upsampler and Dac
Currently using Aurender W20 and a separate Roon Nucleus to provide access access to existing 4TB music files, Quobuz and Tidal and fed directly to a DCS Vivaldi Stack. Is there a better solution that runs extremely quiet with an enjoyable and efficient user interface?
