Thanks for the input fellas, wasn't expecting any replies once I said I realised it can be done.
Current system is a laptop with Jriver MC19 and Spotify Premium, HRT Music Streamer II+, Lehmann Linear H/P amp and Sennheiser H/P's. I've just added an Aqvox PSU to the the HRT and it's sounding perfect for my taste!
It's the laptop that is in question. I just don't like having it on display in the lounge and the process of starting/shutting down and general faffing around. It's currently hidden away in a cupboard and I control Jriver with my Android phone and the Gizmo app.
This got me thinking about a headless Mac Mini or small form factor PC. I've never owned anything Apple, but I've only ever heard positive things.
I've been down the Raspberry Pi route before and have decided it's not what I'm looking for.
So it's Mac Mini or SFF PC with Jriver on the PC and whatever is required on The Mac?
What's your experiences?
