Have an Intel NUC i7 running Roon Core, in my office.
In-home network is Cat6 cabling to a pair of 5 port Gig switches. One is located in the living room where my main system resides, the other is in the family room. Everything homes back to a wireless router in my 2nd floor office. Nothing really different from the norm.
Main system pictured is:
Paradigm speakers Studio 100 Reference
Sim Audio Moon power amp
PS Audio Directstream DAC w/Bridge II
PS Audio Directstream Memory Player
Micro Seiki Turntable, Tonearm
Mac Mini, Apple keyboard and touchpad, Dell monitor
KEF speakers on floor stands, Polk Subwoofer
Onkyo RZ810 surround receiver
Use iPad 6th gen for remote control, mostly.
