Heresy 1. I use a Topping PA3s amp from Schiit Saga preamp from Schiit Modi 3+ DAC streamed from a WiiM mini. Sound great to me will play loud enough to drive you from the room. I have run this from an iMac into Dac w/o the Wiim. Similar results but the iMac will only resolve to 24/96 while the WiiM will do 24/192. Don't really know if my ears or system for that matter resolve well enough for that but I tell myself I can hear a difference.
