I haven’t tried MinimServer, but have been using Roon on a QNAP NAS with a i5 motherboard and 16GB RAM. It sounds great and is fast enough to run Roon’s DSP engine that outputs DSD128. Together with a Sonore microRendu Ethernet-to-USB streamer at the DAC and a Windows tablet for control, this is a simple, relatively inexpensive, high-performance solution that scales easily to mass storage. Setting it up requires just rudimentary IT skills. The high performance and relatively modest price makes me wonder if days are numbered for purpose-built audiophile servers.
