Just to reiterate what I’ve posted elsewhere several times …
I use a NAS running Minimserver on its processor connected to my home network but remote from the hifi. I have a wireless bridge from the NAS area to the hifi area with an optical link in the ethernet run connecting to Bridge II. Playback is controlled by BubbleUPnP running on a tablet. All the hifi runs off a separate mains supply from that for the NAS area. Sound quality is as good or better than from CD played via I2S on a PS PWD. I find this software combination provides all the facilities I need (I’m not interested in looking at album details while I’m listening) but I await with interest to see whether Octave can add something that I value highly enough to adopt.
My conclusion is that NAS + ethernet can produce exceptional sound (at a reasonable cost) if sufficient care is taken with isolation.
