One for Snakeoil/Ubuntu desktop and the other as server with LMS/daphile. Both headless, diskless, and boot from USB. I use upnp/mpd currently as player. Run everything from iPad.
I used to use a server/player configuration both with Daphile. With Snakeoil as player it is more more detailed, 3D. I don’t think mpd is overdetailed/ clinical at all though.. My DAC is tubed (Lampizator B7 MKII) which may help to smooth things a bit and this seems to be the right combination at the moment for me.
Edit: tried to add link but can’t for some reason.
